Question

A pea plant from a pure-breeding strain that is tall, has green pods, and has purple flowers that are terminal is crossed to a plant from a pure-breeding strain that is dwarf, has yellow pods, and has white flowers that are axial. The Fi plats are all tall and have purple axial flowers as well as green pods. 9. a. What phenotypes do you expect to see in the F2 generation? What phenotypes are ratios would you predict in the progeny from crossing an F plant to the dwarf parent? b. 10. A pea plant heterozygous for plant height, pod shape, and flower color was selfed. The progeny consisted of 272 tall, inflated pods, purple flowers; 92 tall, inflated white flowers; 88 tall, flat pods, purple; 93 dwarf, inflated, purple; 35 tall, flat, white; 31 dwarf, inflated, white; 29 dwarf, flat, purple; 11 dwarf, flat, white. Which alleles are dominant in this cross?

Explanation / Answer

in trihybrid cross, maximum 272 plants showing tall, inflated pod purple flower. Maximum amount of phenotypes are shown by dominant alleles. So, dominant alleles would be TALL plant, inflated pod and purple flower.
