Answers
Gamete refers to the haploid germ cell (male or female) which is able to fuse with another gamete of opposite sex of the same species in order to produce zygote.
According to the law of segregation only one copy of the gene (allele) is distributed to each gamete. In addition, it is a random process.
For example, gene Aa would result in the formation of two types of gametes. One will carry A and the other will carry a.
Now, according to the law of independent assortment, alleles of two or more genes are into the gametes independent of each other.
For example, in AABB alleles of gene AA and alleles of BB will be inherited independent of each other.
Now, gametes produced from gg will of only one type that is, g.
Gametes produced by Kk will be of two types which are K and k.
Lastly, all the alleles will be inherited independent of each other which forms two types of gametes. One bearing gK and one bearing gk.

In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. Allele D produces tall plants and is dominant to d for short plants, and allele R produces round fruit and is dominant to r for oval fruit. The expected percentages of progeny phenotypes are listed below:
tall oval = 41%
short round = 41%
tall round = 9%
short oval = 9%
(a) What proportion are expected to be tall and produce round fruit?
Answers
In a diploid plant species, the proportion of progeny expected to be tall and produce round fruit is 32%.
In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. The expected percentages of progeny phenotypes are tall oval = 41%, short round = 41%, tall round = 9%, and short oval = 9%.To determine the proportion of progeny expected to be tall and produce round fruit, we need to consider the alleles for each trait. Allele D produces tall plants (dominant) and allele d produces short plants (recessive). Allele R produces round fruit (dominant) and allele r produces oval fruit (recessive).From the given percentages, we can deduce that tall ovals and short ovals combined make up 9%. Since tall oval is 41% and short oval is 9%, the proportion of progeny expected to be tall and produce round fruit is 41% - 9% = 32%.Therefore, the proportion of progeny expected to be tall and produce round fruit is 32%.For more questions on diploid plant

In which structure do sperm cells develop to maturity?
Answers
Answer: Epididymis
Explanation: The sperms are stored in the spiral structure of the epididymis for maturation and then released.
Sperm cells mature in the structure called the seminiferous tubules within the testes. After developing in these tubules, the sperm move to the epididymis where they continue to mature and then during ejaculation, they exit the body via the vas deferens. This highlights the different stages of sperm development and maturity in the male reproductive system.
Explanation:Sperm cells develop to maturity in a structure called the seminiferous tubules, which are coiled inside the testes. The least developed sperm are located at the periphery of the tubule, while the fully developed sperm are in the lumen. Within the walls of these tubules, the sperm cells are mixed with Sertoli cells, also referred to as 'nursemaid cells', which protect the germ cells and support their development.
Once the sperm cells have developed, they exit the seminiferous tubules and move to the epididymis where they continue their maturation process. The epididymis is a coiled tube located on the top and posterior of the testes. Upon ejaculation, the mature sperm leave the epididymis, travel through the vas deferens, and form the ejaculatory duct.

The seed formed inside the ovary of the flower. As the seed develops in the flower, water is withdrawn from it so that it becomes almost dry. suggest why is it important?
Answers
Water withdrawal from the developing seed inside the flower is important to induce dormancy, enhance longevity, protect against pathogens, facilitate dispersal, and trigger germination under favorable conditions.
Water withdrawal from the seed during its development inside the ovary is crucial for seed dormancy, longevity, protection, dispersal, and germination. Dormancy enables seeds to survive unfavorable conditions. The dry state reduces metabolic activity, enhancing seed longevity. Withdrawing water creates an inhospitable environment for pathogens, safeguarding the seed. Dry seeds are lighter and more easily dispersed by wind, animals, or water, aiding in the colonization of new habitats. Rehydration of the seed after dispersal triggers germination, initiating growth.Overall, water withdrawal from the seed inside the ovary serves as a survival strategy, allowing seeds to endure harsh conditions, remain viable for extended periods, avoid microbial damage, disperse effectively, and germinate when conditions are favorable.

These albinos were so scary looking that I squashed them with a heavy piece of metal over and over again until they were a pile of left over exoskeleton and fluid and let the remaining cockroaches breed. The next generation of these horrid little baby cockroaches totaled 13,485. Assuming that the allele for albinism is recessive and we are still in equilibrium, how many recessive alleles are there in the population. (round to the nearest WHOLE number... 1.234 rounds to 2... there is no such thing as .234 of an organism)
Answers
Answer:
Number of albino cockroaches = 486 cockroaches
Explanation:
Assuming that the population is in Hardy-Weinberg equilibrium and that albinism is recessive, the Hardy-Weinberg equation is used to determine the frequencies ofnthe different alleles in the population
According to the Hardy-Weinberg equation : p² + 2pq + q² = 1
Also p + q = 1
Where p² is the frequency of cockroaches having similar alleles for the dominant trait;
2pq is the frequency of individuals with the heterozygous allele, while q² is the frequency of the individuals having similar allele the recessive trait, albinism.
q² = 24/666
q² = 0.036
Since, the frequency of albinism in the population 0.036, number of individuals with the recessive allele, that is albino cockroaches in the next generation is obtained by multiplying the frequency with the number of individuals in the next generation.
Number of albino cockroaches = 0.036 × 13485
Number of albino cockroaches = 486 cockroaches

Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes leading to a variety of cells
The statements 'each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells' BEST describes how different cell types develop (Option C).
Epigenetics refers to any change in gene expression that does not involve a change in the nucleotide sequence.In an organism, all somatic cells are genetically identical, thereby changes in gene expression are due to epigenetic modifications.These epigenetic modifications include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation, etc).Enzymes that add specific epigenetic marks such as histone acetyltransferases alter the accessibility of transcription factors to chromatin, thereby activating or repressing gene expression.In conclusion, the statements 'each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells' BEST describes how different cell types develop (Option C).

What is albinism?We can infer that the daughter must have the genotype Aa given that the dominant allele (A) is required for normal pigmentation and the couple has a daughter who is normal.
Let's think about the following in relation to the second query concerning the likelihood of an affected boy having het---erozygous dominant parent (Aa) and a recessive parent (aa) if the trait is autosomal recessive:
