Population density is the number of individuals in a population, per unit area or volume.

The average number of people in a population per unit of area or volume is known as population density. For instance, the density of a population of 100 insects living in a space of 100 square meters is equal to one bug per square meter. The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Many different creatures' distribution, growth, and migration can all be described using population density.

Numerous variables influence the density of organisms. Processes like births, deaths, immigration, and emigration can all have an effect on population density at a certain period. Density is linked to some general patterns, though.

We are given two plants. One plant is tall and other is short. We cross these parental plants and find all f1 progeny are tall. We cross the f1 progeny with one another and find the resulting f2 generation is composed of 770 tall plants and 300 short plants. We would conclude polygenic inheritance.

When numerous separate genes have an additive or comparable effect on a single quantitative characteristic, this is known as polygenic inheritance.

Environmental factors have a significant impact on how polygenes express themselves. Quantitative traits have a genotype-determined range, but the phenotype within those ranges is determined by the environment. Different environmental factors affect how genes function. Certain genes are turned on or off by the environment, which also controls their activity.

The term "norm of reaction" refers to the variety of phenotypes that can be produced by the same genotype under various environmental situations. For certain genotypes, the reaction's norm is narrow, whereas for others, it is broad. For instance, the human height-related genotypes have a fairly broad reaction's norm.

The ability to taste the chemical PTC (phenylthiocarbamide) is determined by a single gene, TAS2R38, on chromosome 7. This gene codes for a taste receptor on the tongue that is sensitive to PTC.

The dominant allele (T) produces a functional receptor that can detect the bitter taste of PTC, while the recessive allele (t) produces a non-functional receptor that cannot detect the taste of PTC.

Therefore, individuals who can't taste the chemical PTC exhibit the recessive trait and have a homozygous recessive genotype (tt), as they have two copies of the non-functional allele. In contrast, individuals who can taste PTC can have either a homozygous dominant genotype (TT) or a heterozygous genotype (Tt).

This trait has been studied extensively in genetics research due to its simple inheritance pattern and high frequency of variation in human populations. It is estimated that approximately 25-30% of people worldwide are unable to taste PTC due to their homozygous recessive genotype.

Sex-linked traits are genes carried on the sex chromosomes, the X and the Y chromosome. Only males carry the Y chromosome, and therefore all genes on the Y chromosome are passed down to the son. Women carry two X chromosomes; therefore, sex-linked traits can be passed on from both the mother and the father.

Examples of sex-linked traits include red-green colour blindness and haemophilia.

In codominance, both alleles are expressed in the phenotype of heterozygous offspring. The human ABO blood group is an example of codominance.

There are three alleles for the ABO gene: IA, IB, and I (i is recessive to both IA and IB). If an individual is heterozygous for both the IA and IB alleles, they will express both A and B antigens on their red blood cells. If they are homozygous for either IA or IB, they will express only one antigen on their red blood cells.

Incomplete dominance occurs when neither allele is dominant nor recessive, but instead, the phenotype is a blend of both. An example of incomplete dominance is the snapdragon flower, which has a red flower and a white flower. When the red flower is crossed with the white flower, the resulting offspring have pink flowers, which is a blend of red and white. The genotype for pink flowers is Rr, where R represents the red allele, and r represents the white allele.

When two pink flowers are crossed, their offspring will have a ratio of 1:2:1 of red, pink, and white flowers.
