Vedclass · Answer

(D) This is a test cross where a hybrid individual $(Bb)$ is crossed with a homozygous recessive individual $(bb)$.According to Mendelian genetics,the cross $Bb 	imes bb$ results in a $1:1$ phenotypic ratio of black $(Bb)$ and brown $(bb)$ offspring.Since there are $24$ offspring in total,we expect approximately $12$ black and $12$ brown mice.Furthermore,the inheritance of coat color is independent of sex,meaning the distribution of males and females should be approximately equal within each phenotypic group.Option $(d)$ shows $12$ black mice $(5$ males $+ 7$ females$)$ and $12$ brown mice $(6$ males $+ 6$ females$)$,which perfectly matches the expected $1:1$ ratio for both phenotype and sex.

$A$ black hybrid mouse is crossed with a pure brown mouse to produce a total of $24$ young ones. Which of the following result is most likely to be correct?
