<u>Answer:</u>
<em>There will be 600 tall plants in that generation.</em>
<u>Explanation:</u>
In <em>Mendel’s cross the selected parents</em> are a tall pea plant and a short pea plant. Both the parents are homozygous. The recessive trait is short. Letter T represents tall and t represents short. Hence the <em>phenotype TT is homozygous dominant and tt is homozygous recessive.</em>
The genotype Tt represents tall since T is dominant over t. Mendel’s cross can be represented as
<em></em>
<em></em>
<em>F1 generation Tt Tt Tt Tt</em>
<em>F2 generation TT Tt Tt tt</em>
In the F1 generation all the plants are tall and in the F2 generation 3/4 plants are tall and1/4 plants are short.
In the question it is given that 200 plants are short in the F2 generation. Let total number of offspring in the F2 generation is x.
<em>x=800</em>
<em>number of tall plants = </em>
<em></em>
<em>Hence there will be 600 tall plants in the F2 generation. </em>
