Biology problem
1. A true-breeding line peas with purple flowers, yellow pods, and green seeds (line A), is crossed to a true-breeding line with white flowers, green pods, and yellow seeds. The F1 all have purple flowers, green pods, and yellow seeds.
2. How many loci involved in this cross?
3. A typical line A individual would exhibit how many different pollen genotypes?
4. How many types of gametes can the F1 plants make?
5. How many of the F2 are expected to exhibit all three recessive traits?
