Question

In pea plants, yellow (Y) seed color is a dominant trait, and green seed color (y) is a recessive trait. Which resulting plant with yellow seeds could produce a plant with green seeds in the next generation?

YY


Yy

yy

Yg

Answer 1

Answer: Yy

Step-by-step explanation:
| Y y
——|———|———-
Y I YY I Yy

——|———|———-
y I Yy I yy


This is a punnet square, if you have to Yy (heterogeneous) it produces a 50% chance to have to heterogeneous (Yy) which would leave two out of four to have the same off springs as their parent, they would be yellow but still carry that trait. It would also leave 1/4 to be yellow and be a dominant homogeneous (YY) and 1/4 would be green and carry the recessive homogeneous trait.

Yy - This is the only one that would be able to produce offsprings of both kinds but still be yellow. So it’s resulting (it is) in yellow while also being able to produce at least one green offspring.

Answer 2

Yy

Step-by-step explanation:

Yy has yellow seeds. If breeded with a yy allele, there is a possibility of producing green seeds in the next generation.
