Tall pea plants are dominant over short pea plants. If there are 200 short plants in the F2 generation from a cross that followe
loris [4]

<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>Tall \times Short</em>

<em>TT \times tt</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.

1/4 \times x=200

<em>x=800</em>

<em>number of tall plants = 3/4 \times x</em>

<em>= 3/4 \times 800 =600</em>

<em>Hence there will be 600 tall plants in the F2 generation. </em>
