Answer:
3/16
Explanation:
The P generation is said to gave homozygous yellow and round seeds; homozygous green and wrinkled seeds. Homozygous means that they have the same alleles for the trait.
For the P generation the cross would be:
YYRR x yyrr
This means that all offsprings in the first generation (F1) would have a genotype of:
YyRr
16/16
(Look at the Punnett attached to see this cross.)
The cross in the F1 generation would then be:
YyRr x YyRr
Now for yellow and wrinkled seeds to come out, the genotype should have at least one Y allele and a pair of r alleles. So the following genotypes is what you need to look out for:
Yyrr
YYrr
So if you will count it you will find:
Yyrr = 2/16
YYrr = 1/16
Just add them up to get the probability:
3/16
