Genetics: A Conceptual Approach 6th Edition MHE/Freeman ap- On average, what fraction of the genome in the following pairs of humans would be exactly the same if no crossing over took place? For the purposes of this question only, we will ignore the special case of the X and Y sex chromosomes and assume that all genes are located on non-sex chromosomes. Also, assume that the uncle and niece are related by a sibling and not by marriage alone Father and child Mother and child Full siblings Half siblings Uncle and niece Grandparent and grandchild Check Answer Exit

Explanation / Answer

1. mother and child have same genome content approx 50%.

father and child have same genome content approx 50%.

In offsprings half genetic content means 50% comes from mother and 50% comes from father.

so father and child have 50% genetic content similarity.

Mother and child have genetic content similarity approx 50%.

Siblings characters are download from the transmission of from mother and father. in a sense we can say that siblings have same genetic content.

Father child: 1/2

mother child: 1/2

fullsiblings : 1

half siblings: 1

Uncle and neice : 0
