In a plant species, a segregating line (RR- Red, Rr- Pink and rr- white) that contains both homozygotes and heterozygotes at a locus can be made homozygous by repeated selfing for several generations. What is the proportional red flower in third generations of selfing, if the level of heterozygosity in generation '0' is denoted as 1?

#Section 3: Genetics, Cellular and Molecular Biology
In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for these two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. If an F1 plant is backcrossed with the bitter, yellow spotted parent, what phenotypes and proportions are expected in the offspring?
