Practice question
Question
In a diploid angiosperm species, flower colour is regulated by the R gene. RR and Rr genotypes produce red flowers, whereas the rr genotype produces white flowers. If two individual plants are randomly selected from a large segregating population of a genetic cross between RR and rr parents, the probability of both the plants producing red flowers is _______. (Rounded off to two decimal places) (NAT)
Explanation
Mechanistically, Mendelian segregation involves allele distribution and recombination generate phenotypic variation. This validates Option NAT because it follows segregation and linkage principles, a pattern repeatedly demonstrated in genetics research. This mechanism is extensively documented and reinforced by experimental data across multiple model systems and textbook discussions.
