Tallness (T ) in snapdragons is dominant to dwarfism (t ), while red (R ) flower color is incompletely dominant to white (R' ). The heterozygous condition results in pink (RR' ) flower color. The genes for these traits occur on separate chromosomes. A dwarf, red snapdragon is crossed with a plant homozygous for tallness and white fowers. a) Determine the genotypes of the parents. b) Determine all the types of gametes each parent can produce. c) Complete the Punnett...

In apples, red skin colour ‘R’ is dominant to yellowish-green skin colour ‘r’, and stems with no leaves ‘S’ are dominant over stems with leaves ‘s’. The mating of two apple varieties yielded the following progeny: 380 no leaf stem, red apples; 371 no leaf stem, yellow apples; 131 leaf stem, red apples; and 100 leaf stem, yellow apples. What were the genotypes of the parents in this cross?

In corn, the trait for yellow seedlings (g) is recessive to green seedlings (G), and waxy endosperm (w) is recessive to starchy endosperm (W). The two genes assort independently. A cross between a homozygous green, waxy plant and a homozygous yellow starchy plant produced F1 progeny that were all phenotypically green, starchy. a) If F1 individuals are interbred (self-pollinated), what phenotypes and in what proportions (ratios) would you expect in the F2 generation progeny b) List the expected F2 genotypes...
