Question

2. A heterozygous plant is crossed with another heterozygous plant. Tell the following
a. What are the two genotypes? _
b. % of offspring that will be homozygous dominant ___________
c. % of offspring that will be heterozygous ___________
d. % of offspring that will be homozygous recessive ___________
e. % of offspring that will be tall ___________
f. % of offspring that will be short__________

Answer 1

Answer:

A: Tt, Tt

B: 25%

C: 50%

D: 25%

E: 75%

F: 25%

Explanation:

Heterozygous has Tt. Homozygous had TT or tt.  Punnett square:

   T       t

T TT    Tt

t  Tt      tt

1/4 of the offspring are homozygous recessive(tt). That means they are short.  1/4 are homozygous dominate (TT) they are tall.  1/2 is heterozygous(Tt), they are tall.
