Genetic recombination occurs during meiosis in sexually reproducing organisms, leading to the production of offspring with combinations of traits that differ from those found in either parent. The closer two genes are on a chromosome, the less likely they are to Show more…

Consider two independently assorting genes that both produce the same phenotype in the homozygous recessive state. You cross two such individuals: aaBB x AAbb. What phenotypes would you expect from this cross? 3:1; wild type: recessive phenotypes All progeny would exhibit the recessive phenotype All progeny would exhibit the wild type phenotype 1:1; wild type: recessive phenotypes

Allele pairs are most likely to assort independently of one another when they control unrelated traits. they control related traits. they are on the same chromosome. they are sex linked. they are on different chromosomes.
