Normally you cant inherit both copies of a homologous chromosome from the same parent. Why? Assuming that no crossing over has occurred, how likely is it that one of your non-sex chromosomes is an exact copy of the same chromosome your maternal grandmother had? Explain your answer.
Human females have two X chromosomes (XX); males have one X and one Y chromosome (XY). a. With respect to X-linked alleles, how many different types of gametes can a male produce? b. If a female is homozygous for an X-linked allele, how many types of gametes can she produce with respect to that allele? c. If a female is heterozygous for an X-linked allele, how many types of gametes can she produce with respect to that allele?
Human females have two X chromosomes XX; males have one X and one Y chromosome XY. a. With respect to X-linked alleles, how many different types of gametes can a male produce? b. A female homozygous for an X-linked allele can produce how many types of gametes with respect to that allele? c. A female heterozygous for an X-linked allele can produce how many types of gametes with respect to that allele?
A man is homozygous dominant for ten different genes that assort independently. How many genotypically different types of sperm could he produce? A woman is homozygous recessive for eight of these genes and is heterozygous for the other two. How many genotypically different types of eggs could she produce? What can you conclude about the relationship between the number of different gametes possible and the number of heterozygous and homozygous gene pairs that are present?

On average, what fraction of the genome in the pairs of humans would be exactly the same if no crossing over took place? For the purposes of this question only, ignore the special case of the X and Y sex chromosomes and assume that all genes are located on nonsex chromosomes. Also, assume that the uncle and niece are related by a sibling and not by marriage alone.

Suppose you discover two interesting rare cytological abnormalities in the karyotype of a human male. (Akaryotype is the total visible chromosome complement.) There is an extra piece (satellite) on one of the chromosomes of pair 4, and there is an abnormal pattern of staining on one of the chromosomes of pair 7. With the assumption that all the gametes of this male are equally viable, what proportion of his children will have the same karyotype that he has?
