What is the relationship between the number of active genes and color of the skin

Biology
1 answer:
Leto [7]3 years ago
3 0

Skin color is polygenic trait meaning a lot of genes are significant in the expression of the trait. Such traits can have a multitude of variations showing continuous distribution because these non-epistatic genes have a cumulative effect on the skin color. The level of expression of these genes, majorly based on influence from the environment, will determine skin color. For example; the expression of the gene for melanin will be high in a person within the equator than in a person at the poles due to differences in sunlight exposure.

To have a 100% chance of having offspring with the recessive genotype, what must be the genotypes of each parent
Ronch [10]

Answer:

To have a 100% chance of having offspring with the recessive genotype, each parent's genotype must be homozygous recessive.

Explanation:

For a recessive trait to be phenotypically evident it is necessary that the two alleles that form it are recessive, that is, that they are recessive homozygous.

The presence of a single dominant allele in one parent will probably suppress the expression of the recessive gene in at least half of the offspring.

<u>For the offspring to be 100% recessive, both parents must have a homozygous recessive genotype</u>.
