Answer:

The brown version of gene 1 is dominant over the blue one. Dominant means that if at least 1 of your two copies is brown (Bb), then you will have brown eyes. Geneticists represent the different versions of the eye colour gene as B for brown and b for blue (the capital letter is the dominant, the lowercase, recessive).

Explanation:

Option 1 is Correct. The following three sexual reproduction-related factors are the principal causes of genetic variation: stepping over (in prophase I) A haphazard collection of chromosomes (in metaphase I) randomly combining gametes from many parents.

Mutation, which can produce completely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis, which reorders alleles within an organism's progeny, are all possible sources of genetic variation.

There is a huge possibility for genetic variety due to this autonomous assortment, which allows the chromosomes acquired from either the mother or the father to sort into any gamete. One gamete from each parent joins together to produce a zygote during fertilization. Each gamete has a unique DNA set because of recombination and independent assortment during meiosis. This results in a distinctive mix.

Explanation:This often happens with siblings as a sort of rivalry.

The siblings will start competing with each other to get better grades. The correct answer is B.

A conflict will arise when there is a difference between actions or thoughts among two or more people.

Tamir will develop a sense of superiority over his sister only on the basis of earning better grades. Thus, to maintain that position, he will try his best to consistently score more than his sister.

Whereas, his sister will develop a sense of inferiority or insecurity due to scoring lesser than him. Due to this, she will be determined to score more than him in every upcoming exam and defeat him.

This will lead to a sense of competition to achieve more than the other in every examination.

Answer:

Mendel's cross-pollination experiments with pea plants proved that different characteristics (such as seed color) are determined by inherited factors (now known as genes) that are passed from parent to offspring. He found that certain characteristics were dominant, meaning they would appear in the offspring even if only one parent had that characteristic. Other characteristics were recessive, meaning they would only appear in the offspring if both parents had that characteristic.Mendel's experiments also showed that each parent contributes one copy of each gene to the offspring, and that the combination of these genes determines the characteristics of the offspring. This is known as the principle of segregation, and it is the basis for our understanding of how traits are inherited.Mendel's work also led to the discovery that genes are found on chromosomes in all cells of an organism. In fact, Mendel's work laid the foundation for the modern understanding of genetics and he is considered the "father of modern genetics."

The characteristic that distinguishes all chordates from all other animals is the presence of a (c) dorsal, hollow nerve cord.

This nerve cord is located along the back (dorsal) side of the organism and runs longitudinally. It is formed from a folding of the ectoderm during development and gives rise to the central nervous system, including the brain and spinal cord, in vertebrates.

The dorsal, hollow nerve cord serves as a fundamental feature of chordates, playing a vital role in coordinating and transmitting nerve impulses throughout the body. It is unique to chordates and sets them apart from other animal groups.

While other characteristics listed in the options, such as bilateral symmetry, collar cells, a vertebral column, and amniotic egg, may be present in specific groups of chordates or other animals, the dorsal, hollow nerve cord is a defining characteristic that is shared by all chordates.

The freezing temperatures of the saguaro cactus determine the maximum tolerance limit and how far north this species can be found, because any further north the caucus would freeze, killing the plant's growing tips and halting development.

The minimum and maximum levels of a specific environmental factor that an organism can tolerate are known as tolerance limits. Because the saguaro cactus has very specific and limited tolerance limits, it cannot survive in many environments that do not fit its limits.

Saguaros can withstand cold temperatures, but not for an extended period of time. They'll be fine if the temperature drops to 20 degrees for six hours, say. However, if they are exposed to sustained subfreezing temperatures for more than six or eight hours, they begin to suffer damage.

The genetic composition of gametes derived from tetrads of inversion heterozygotes C. Crossing over in the inversion loop of a pericentric heterozygote produces all chromatids with centromeres.

During crossing over within a pericentric inversion, the two homologous chromosomes form a loop structure, which can lead to an exchange of genetic material between non-sister chromatids. In this case, the exchange occurs within the inverted segment of the chromosome.

Due to the inversion, the two chromosomes have different gene orders, which can lead to genetic imbalances in the gametes produced by crossing over. If crossing over occurs within the inversion loop, it results in two types of chromatids: one with an inverted segment and the other with a normal sequence.

Therefore, gametes derived from tetrads of inversion heterozygotes where crossing over occurs within a pericentric inversion will have two genetically unbalanced gametes with inverted sequence and two genetically unbalanced gametes with normal sequence. The genetic composition of the gametes will be different from the parental chromosomes, which can result in offspring with genetic disorders or reduced fertility.

Explanation:

The correct answer is c. random differences in survival and reproduction among the individuals in a population.

Genetic drift is a mechanism of evolution that refers to the random fluctuations in allele frequencies within a population over time. It occurs when certain alleles become more or less common in a population due to chance events rather than natural selection. These chance events can include random differences in survival and reproduction among individuals in a population, which can lead to the random loss or fixation of alleles. Genetic drift is particularly influential in small populations where chance events can have a more significant impact on allele frequencies.

False statements about the parathyroid gland are “it is posterior to thyroid” and “the hormone release is triggered by a rise in blood calcium.”

The parathyroid glands are not posterior to the thyroid gland; they are typically located on the posterior surface of the thyroid gland or in close proximity to it. The exact location of it is in the neck, behind the thyroid gland.

The release of parathyroid hormone (PTH) is triggered by a fall in blood calcium levels, not a rise in blood calcium. The parathyroid glands play an important role in regulating calcium levels in the blood. When blood calcium levels fall, the parathyroid glands secrete PTH, which promotes the release of calcium from bones, increases the absorption of calcium in the gut, and stimulates the kidneys to conserve calcium.

There are usually four parathyroid glands in the human body and it secretes parathyroid hormone (PTH), which is a peptide hormone.
