Consider crosses between individuals of different heritable phenotypes.Under which condition will the phenotype of the offspring most likely be influenced by which parent has which phenotype?
A) In cases involving sex chromosomes
B) In cases involving epistasis
C) In cases involving pleiotropy
D) In cases involving codominance
E) In cases involving closely linked genes

Question

Quizplus · Accepted Answer

In cases involving sex chromosomes, the phenotype of the offspring can be significantly influenced by which parent has which phenotype due to the different composition of sex chromosomes (X and Y) in males and females. This can lead to sex-linked traits where the expression of a gene located on a sex chromosome is dependent on the sex of the individual, making the parent's sex crucial in determining the phenotype of the offspring.
