Suppose you have monohybrid snapdragons in your garden and you find that they produce red seeds to white seeds in the ratio 3: 1. if the alleles are designed r (red seeds), what are the probable phenotypes of the parents?

The phenotype of the parents will be all red.

The monohybrid snapdragons are generating red and white seeds in the ratio 3: 1 with the white (r) phenotype being recessive and the red (R) phenotype being dominant. Thus, they would possibly have the parents exhibiting genotypes, Rr and Rr, that is, both red.

The gametes generated by these parents are R and r. The cross of these parents will lead to the formation of the following generation shown in the cross below, that is, in the ratio 3: 1 (red: white).

✿   this landform has a high elevation and a high relief

✿   this landform is a mountain

yes? sounds right, but you didn’t ask a question.
