In a monohybrid cross between two organisms heterozygous for a particular trait (Ff), what would be the predicted ratio of the offsprings genotype?

What would be the result if crossing over did not happen during meiosis in humans? a. there would be less genetic variation in humans. b. parents would be more likely to look like their children. c. the human population could not reproduce. d. children would have more chromosomes.

Which would be the most useful source of evidence to support mcneill's contention?

In sheep, the allele for belly fur (a) is dominant to the allele for no belly fur (a). a mother with the genotype aa and a father with the genotype aa produce an offspring.
