Question

2 multiple choice 20 points which punnett square shows a cross between a heterozygous tall (tt) plant and a homozygous short (tt) pea plant? a. c. tt tt tt tt tt tt tt tt b. d. tt tt tt tt tt tt tt tt a b c d

Explanation:

A Punnett square is used to predict the genotypes of a particular cross. A heterozygous tall plant (Tt) can produce two types of gametes: T and t. A homozygous short plant (tt) can only produce t - gametes. When we set up the Punnett - square, we put the gametes of one parent on the top and the gametes of the other parent on the side. The possible combinations from the cross of Tt and tt are Tt and tt.

Answer:

C. Tt, tt; Tt, tt
