Q1. Genes A/a and B/b are linked and known to be 20 map units apart. Individuals heterozygous for both of these genes (genotypes= AB/ab) were mated with each other. If there 2000 offspring from this cross, how several of the offspring will you expect to show Ab or aB phenotypes? […]

What is Mendel’s Concept of Dominance? Answer A. The two members of a gene pair segregate from each other into the gametes, so half the gametes carry one member of the pair, half the gametes carry the other member of the pair. B. In a heterozygote, only the trait from […]

Yet there is increasing evidence that mass extinctions are selective even though they follow different rules to “background” extinction. What […]
