Final answer:
Fitness is a measure of reproductive success in the context of evolution by natural selection. The fitness value for the individual with genotype (bb) can be calculated by comparing its offspring count to the offspring counts of other genotypes. In this scenario, the fitness value for the individual with genotype (bb) would be 0.5.
Step-by-step explanation:
Fitness is a measure of reproductive success in the context of evolution by natural selection. It is the relative ability of an organism to survive and produce fertile offspring compared to the rest of the population. In this scenario, an individual with genotype (bb) produced 6 offspring, while a heterozygous individual with genotype (Bb) produced 10 offspring, and another individual with genotype (bb) produced 5 offspring.
To calculate the fitness value for the individual with genotype (bb), we need to compare its reproductive success to that of the other genotypes. The fitness value for each genotype can be calculated by dividing its offspring count by the highest offspring count among all genotypes. In this case, the highest offspring count is 10 (produced by the heterozygous individual).
The fitness value for the individual with genotype (bb) would be 5/10 = 0.5. This means that the individual with genotype (bb) has half the reproductive success compared to the heterozygous individual (Bb).
