Question

In pea plants, purple flowers are dominant over white flowers. Two plants, both heterozygous for the gene that controls flower color, are crossed. What percentage of their offspring will have purple flowers?

a. All or 100%
b. 3/4 or 75%
c. 1/2 or 50%
d. 1/4 or 25%
e. none or 0%

Answer 1

b .75%

Step-by-step explanation:

If you do a genetic croas or punnet square , you will find that the genotype of the filial generation is : Pp, PP , Pp ,Pp and pp.

if purple is (P) dominant

if white is (p) recessive

the ratio of purple : white

=. 3:1

thefore 3/4 chances

Answer 2

100%

In the given question, the allele for dominant trait is dominant to white flower. Then all the progeny will be white therefore 100% is the correct answer.
