Answer:
The percentage for the homozygous dominant trait would be 25%. in the F2 generation.
Explanation:
Suppose true-breeding parents with the different alleles for the same trait are TT (dominant) and tt (recessive) than the cross of these parents will produce gametes T, T and t, t respectively.
These gametes will form offspring ultimately. Produced offspring will be TT (homozygous dominant), Tt (heterozygous dominant), Tt (heterozygous dominant) and tt (homozygous recessive).
Thus, the percentage of dominant homozygous phenotype in F2 would be 25% in respect of the dominant allele which is TT.
The theory of natural selection is one of the most influential scientific theories about the evolution of living organisms wherein it was first formulated by the famous Charles Darwin. It is described as the adaptation of an organism to an environment in order for it to survive with variation in its traits.
D. cause bacterium are single celled organisms.
