Question 9 (1 point) In peas, long stem (A) is dominant over short stem (a). A heterozygous, long stem plant (Aa) is crossed with a homo-zygous, short stemmed plant (aa).
Which of the above squares represent plants that are heterozygous?

Question 9 options:
Box 1
Box 1 and box 2
Box 1 and box 3
Box 2 and box 3

Box 1 and 3

Explanation:

Box 1 represents the allele Aa

Box 2 represents the allele aa

Box 3 represents the allele Aa

Box 4 represents the allele aa

So the answer is Box 1 and 3 because Aa is a heterozygous allele and aa is a homo-zygous allele.

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

answer: the answer is b
