NEET BIOLOGY

Detailed explanation-1: -RR x rr. You’ll note that 100% of all offspring are Rr, which is the genotype. Since the genotype for all offspring are the same, and the Rr genotype encodes a pink color, then 100% of the phenotypes will be pink (NOT red-remember that this is incomplete dominance).

Detailed explanation-2: -The cross between Rr, a plant with heterozygous condition for red flowers and rr, a plant with homozygous recessive condition with white flowers will produce two types of genotypes in progeny-Rr and rr in equal proportions.

Detailed explanation-3: -For example, a test cross between two organisms with the same genotype, Rr, for a heterozygous dominant trait will result in offspring with genotypes: RR, Rr, and rr. In this example, the predicted genotypic ratio is 1:2:1.

Detailed explanation-4: -Complete answer: Three different genotypes are possible to form a cross between the parents RR and rr.

Detailed explanation-5: -A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group. It does so by dividing the risk (incidence proportion, attack rate) in group 1 by the risk (incidence proportion, attack rate) in group 2.
