PLEASE HELP!!! In a certain plant, yellow leaves are dominant (Y) and red leaves are recessive (y). A plant with genotype Yy and a plant with Yy are crossed. If they have four offspring, how many would you predict would have red leaves? (Hint: Draw a Punnett square to help you determine the answer.)

A.1
B.0
C.3
D.4

Answer:

One offspring will have red leaves; A is the answer.

Step-by-step explanation:

Punnet Square:

Y y

Y YY | Yy

y Yy | yy

Dominant trait = a common trait

Recessive trait = a rare trait

Genotype = the makeup of the organism's genes

  • One offspring has the genotype YY; they don't carry the recessive trait, nor do they have it. This offspring has the dominant genotype and carries it with them.
  • Two offsprings have the genotype Yy. These plants have the dominant trait, but they carry the recessive trait with them. So, a few of their offsprings could get the recessive genotype.
  • One plant has the genotype yy. This offspring has the recessive trait AND carries it with them.

I hope this helps! :)

Please do not vote this, nor give it 5 stars until you know that this answer is right. Also, please read the explanation, it'll help you answer questions like these in the future.
