#Section 2: General Biology

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?
