n this scenario, the homozygous recessive parent would have the genotype "rr" and would only produce gametes carrying the recessive allele "r". The homozygous dominant parent would have the genotype "RR" and would only produce gametes carrying the dominant allele "R".
When these two parents mate, all of their offspring will inherit one "R" allele from the homozygous dominant parent and one "r" allele from the homozygous recessive parent. Therefore, all of the offspring will have the genotype "Rr" (heterozygous).
The trait for seed color is governed by a single gene with two alleles: "Y" for yellow and "y" for green. The "Rr" genotype does not directly determine seed color, but instead, it determines the likelihood of inheriting a certain trait.
Assuming that the yellow seed allele is dominant over the green seed allele, the probabilities of yellow and green seeds in the offspring can be calculated using a Punnett square:
R | r
----|----
R | RR | Rr
r | Rr | rr
As shown in the Punnett square, all of the offspring will have the genotype "Rr". However, because the "Y" allele is dominant over the "y" allele, all of the "Rr" offspring will have yellow seeds. Therefore, the probability of yellow seeds is 100%, and the probability of green seeds is 0%.
