🤓 Based on our data, we think this question is relevant for Professor Upadhyaya's class at USF.
In the organism under consideration, r* acts like r allele, except when homozygous (r*r*). From the information given below, work out the phenotypic and genotypic ratios for each of the crosses.
Given: RR (red) x rr (white) → Rr (pink); and
rr* x rr* → 3/4 white, 1/4 dead zygotes
1. Rr x Rr
2. Rr x rr
3. Rr* x Rr*
4. Rr* x rr*
