Phenotypes and Genotypes of Tomato Fruits

To determine the phenotypes and genotypes of tomato fruits with pear-shaped form and red color, as well as yellow color and round form, we need to understand the genetic basis of these traits.

The shape of tomato fruits is determined by a single gene, with the dominant allele (S) responsible for the round shape and the recessive allele (s) for the pear-shaped form. The color of tomato fruits is also determined by a single gene, with the dominant allele (R) responsible for the red color and the recessive allele (r) for the yellow color.

Based on this information, we can determine the phenotypes and genotypes of tomato fruits with specific characteristics:

1. Tomato fruits with pear-shaped form and red color: - Phenotype: Pear-shaped form, Red color - Genotype: ssRR or ssRr

2. Tomato fruits with yellow color and round form: - Phenotype: Round form, Yellow color - Genotype: Ssrr or ssrr

Please note that the genotypes provided are just a few possibilities, as there can be other combinations of alleles that result in the same phenotypes. Additionally, the genotypes provided assume that the parents of these tomato fruits are homozygous for the respective traits.

I hope this helps! Let me know if you have any further questions.
