Vedclass · Answer

(A) In a monohybrid cross between two heterozygous individuals $(Bb 	imes Bb)$,the phenotypic ratio of the offspring is $3:1$ (dominant to recessive).For any single offspring,the probability of showing the dominant trait is $3/4$ and the probability of showing the recessive trait is $1/4$.Since the birth of each offspring is an independent event,the outcome of the first offspring does not influence the outcome of the second offspring.Therefore,the probability that the second offspring will show the recessive trait remains $1/4$.

If two individuals with genotype $Bb$ are crossed and they produce two offspring,what is the probability that the second offspring will show the recessive trait,given that the first offspring shows the dominant trait?
