Only the strongest survive
To exhibit a recessive trait, an individual must have two recessive alleles responsible for the trait. One recessive allele is from a mother and another is from a father. However, if a person has one dominant and one recessive allele, it will not exhibit the recessive trait. This is because recessive allele will be masked by the dominant allele. So, parents must be heterozygous (one dominant and one recessive allele) and must give their recessive alleles to the offspring so that only offspring exhibit the recessive trait.
The zygote is the answer.
After fertilization, the process of sperm and the egg cell meeting and undergoing conjoint process a zygote is formed. A zygote now here is formed because of the combined gametes of the parent sperm and parent egg. The DNA that prevails in the zygote is the genetic material of the parent cell.
epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue , through the basement membrane.
