|
|
They will all carry the r allele.

Explanation:
Detailed explanation-1: -If a person has a genotype of RR, what do you know about their gametes (sex cells)? They will all carry the R allele.
Detailed explanation-2: -Answer and Explanation: To solve this, first determine the genotypes of the possible gametes for each heterozygous parent (Rr): Both parents can make gametes of genotypes R and r in equal proportions.
Detailed explanation-3: -RR’ 50% of the offspring have genotype RR’ and 50% have genotype R’R’. This means that 50% of the offspring are white and 50% of the offspring are pink. A cross between a red and white flowered plant would give the most poink-flowered plants-100%.
