Answer:
A female Drosophila of unknown genotype was crossed with a white-eyed male fly, of genotype (w = white eye allele is recessive, w+= red-eye allele is dominant.) Half of the male and half of the female offspring were red-eyed, and half of the male and half of the female offspring were white-eyed.If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous.The female fly had to be heterozygous, Xw+ Xw.
Explanation:
The DNA in our cells nucleus is wrapped around proteins called histones, forming chromosomes which in turn codes for our genes.
-In Africa savanna more wildebeest are born than the environment can support. As a result over a period of years individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce. This is referred to as natural selection.

digestion, an amino acid not absorbed by the body and not used to build
proteins will first be subjected to removal from its amino group. If they are
not used for protein synthesis, amino acids becomes part of the metabolism
process. The body has the capability to create a subset of amino acids, also
known as non-essential amino acids because we don’t have requirement for them
in our diet. </span>
