In tomatoes, the round shape of the fruit dominates over the pear-shaped. Red color of the fruit dominates

In tomatoes, the round shape of the fruit dominates over the pear-shaped. Red color of the fruit dominates over yellow. Plants with round red fruits interbreed with plants with pear-shaped yellow fruits. All individuals are homozygous. What are the genotypes of the parents. Of the first generation hybrids? F1 F2

Let’s designate the gene that leads to the development of round fruits in tomatoes as C, then the pear-shaped gene of tomatoes will be designated as c. Let the gene for the red color of tomato fruits be P, then the gene for their yellow color will be p.

Homozygous tomatoes with a red round fruit – CCPP, they produce germ cells of CP.

Homozygous tomatoes with a yellow pear-shaped fruit – ssrr. They produce sex cells cp.

All F1 offspring are represented by CcPp diheterozygotes with red and round fruits. These hybrids produce sex cells cp, cp, cp, cp.

F2 offspring, obtained from crossing hybrids with each other, will be represented by the following options:

tomatoes with red round fruit (CCPP, 2CcRP, 2CCPp, 4CcPp);

tomatoes with a yellow round fruit (2Ссpp, ССрр);

tomatoes with red pear-shaped fruit (ccPP, 2ccPp);

tomatoes with a yellow pear-shaped fruit (ccpp).
