Question

Fruit color in the pepper Capsicum annuum is an example of a two-gene interaction. A pure-breeding plant with red fruit is crossed with a pure-breeding plant with cream fruit. If you crossed a resultant plant with an orange plant having the genotype yyCc, what proportion of the offspring would be peach?

Answer 1

The proportion of offspring that would be peach is
`(1)/(8)`

Step-by-step explanation:

Let's first put down the genotype for the F1 offspring after the pure breeding plants are crossed. From the Red fruit and Cream fruit plants, the offspring would all be RRCC. Crossing the RRCC with yyCc gives the following genotypes:

RyCC, RyCc
