Question

Considering the Mendelian traits tall (D) versus dwarf (d) and violet (W) versus white (w), consider the crosses below and determine the genotypes of the parental plants by analyzing the phenotypes of the offspring.

Answer 1

Explanation:for a mendelian cross between a Talk(D) and a dwarf individual (d)

DD×dd= Dd Dd Dd Dd

The offspring will be heterozygote all loci i.e all the offspring will be tall this is because one of the parents carries a dominant gene for tallness and the other parent carries a recessive gene for tallness.

This may not follow for the progeny's offspring as segregation will occur at the 2nd filial generation.

The same principle applies for violet and white, progeny will be heterozygous at all loci i.e violet color
