linkage and epistasis

Question 1

why are males more likely than females to show recessive phenotypes for genes that are sex linked

Answer 1

males only have one X chromosome often only have 1 allele for sex linked disease

Question 2

Autosomal genes

any chromosome thats not a sex chromosome

Answer 2

genes on same autosome said to be linked
stay together during independent segregation
alleles passed on to offspring together
unless crossing over splits them up

Question 3

epistasis

Answer 3

allele of one gene masks expression of the alleles of other genes
