Ascientist is studying a cross between plants that are heterozygous (xx) for a certain trait. she will use a table similar to this one to make a punnett square for the cross. which percentage of offspring will most likely have the genotype represented by the letter a in this table? 0% 25% 50% 75%

Option B, %

Explanation:

The heterozygous genotype of the parent is Xx

The punnet square for the cross between the two parents having Xx genotype is  

Xx

XXXXx

xXxxx

Thus,  

A represents the genotype – XX

B represents the genotype – Xx

C represents the genotype – Xx

D represents the genotype – xx

Out of four possible genotypes, XX (A) appears only once.

Thus the probability of occurrence of genotype A (XX) will be  

%

B, 25 percent

Explanation:

hope i got it right

what are the options
