Crossing of two dissimilar genotypes is
WebFeb 7, 2024 · What is the homozygous genotype? Homozygous genotype occurs when two alleles (versions) of a given gene are identical. We can distinguish: Homozygous-dominant genes where both of the alleles are dominant (typically visible in offsprings), e.g., AA; and Homozygous-recessive where both genes are recessive (often not visible in offsprings), … WebWhen Mendel examined the inheritance of two traits in a dihybrid cross in pea plants, he observed that both traits were always transmitted together to the offspring. False The chromosome theory of inheritance proposes that genes are composed of many different chromosomes. False
