PLEASE HELP, WILL GIVE BRAINLIEST

Answer 1

Answer:

D

Explanation:

The punnett square showing the cross Yyrr x YyRr is attached

The gametes that the Yyrr individual can produce are either Yr or yr. The yyRr individual can produce YR, Yr, yR, or yr. The possible genotypes are shown in the punnett square.

For a pea to be yellow and wrinkled, it would have the genotype YYrr, or Yyrr (as yellow is dominant (Y) and wrinkled is recessive (r)). Therefore, we count the number of those genotypes of the total genotypes we get.

There are 4/8 that are either Yyrr or YYrr, so the answer is d.

Answer 2

Answer:

It shold be three out of 8 or C. 3/8

Explanation:

So first try to fill out the punnet square (I know you wont because your lazy) anyway after you have filled out the square count the number of Yr-s in your box because we are looking for Y (yellow) and r (red)

I found six out of sixteen or 6/16 which (if you know basic division) simplifies to 3/8 and that is your answer
