a.
To construct: A Punnett square and list the possible fruit fly offspring genotypes that would be expected in the F2 generation if the two genes were completely linked.
Introduction: A Punnett square is made to know about the possible traits that may be inherited by the offspring after a genetic cross. It is used to predict the allele combinations which represent genotype and
b.
To construct: A Punnett square and list the possible fruit fly offspring genotypes that would be expected in the F2 generation if the two genes were on different chromosomes.
Introduction: A Punnett square is made to know about the possible traits that may be inherited by the offspring after a genetic cross. It is used to predict the allele combinations which represent genotype and phenotype of the offspring produced. An experiment is conducted in fruit fly with inheritance of two genes- one with allele A or a, the other with allele B or b.
