Question

URGENT!!

The Punnett square in figure 11-2 shows the gene for pea seed shape and the gene for pea seed color. What is the phenotype of offspring from a round yellow seed plant and a wrinkled green seed plant?

A) round yellow seeds
B) wrinkled yellow seeds
C) round green seeds
D) wrinkled green seeds

Answer 1

The answer is round yellow seeds.

Step-by-step explanation:

I took the test and round yellow seeds is correct.

Answer 2

Although figure is not attached in the answer but as per past knowledge it can be answered.

What is the phenotype of offspring from a round yellow seed plant and a wrinkled green seed plant?

There are two parents, one is wrinkled green and the other is round yellow. For wrinkled green, the genotype will definitely be rryy because both are recessive traits. For round yellow seed parents, the genotype can be either RRYY, or RrYy. Let's cross them one by one.

Condition 1:

rryy x RrYy

Gametes: ry RY or Ry or rY or ry

Offspring: RrYy : Rryy: rrYy: rryy

1/4 : 1/4 : 1/4: 1/4

So, in this situation the phenotype of 1/4 will be round yellow (RrYy), 1/4 will be wrinkled yellow (rrYy),1/4 will be round green (Rryy), 1/4 will be wrinkled green (rryy).You can see the punnet square in figure for better understanding.

Condition 2:

rryy x RRYY

Gametes: ry RY

Offspring : RrYy

In this scenario, all of the offspirng will have the genotype of RrYy and the phenotype will be round and yellow.You can see the punnet square in figure for better understanding.

Hope it helps! :)
