Answer 2

Answer:

In the F2 generation, 1000 plants out of 2000 plants are homozygous for only one character.

Explanation:

In the mendelian dihybrid cross experiment, 8 out of a total of 16 plants (e.g., RRYy-2, RrYY-2, Rryy-2, and rrYy-2 ), are homozygous for a single character in the F2 generation.

Thus, if 8 plants out of 16 plants are homozygous for a single character, then the number of plants homozygous for a single character out of 2000 plants are:

8/16×2000

=1000

Thus, 1000 plants out of 2000 plants are homozygous for a single character in the F2 generation.
