Document Summary
Staining is result of treating those with mild protease to remove just a little protein. Stripey pattern is the same on each of the #1 chromosomes. The human x and y chromosomes came from homologous autosomal chromosomes. Pseudo autosomal region: par; in these two pars on the x and. The differences btwn reciprocal crosses is a hallmark of x-linkage. Don"t do x^w+ w you need to remember a female has 2 x chromosomes and each x only carries one of allele of that gene. Males cannot inherit an x-linked trait from their fathers. If female is carrier the trait is often not exhibited. Hemizygous: only one copy of that gene in that individual, like only on the x or only on the y. Typically x-linked dominant is shown higher in females, the tissues that are affected by whatever the trait is. Afected fathers: all daughters affected (depends on x inactivation), no sons affected.
