Document Summary
I "t female male females slightly less likely to survive from conception to birth ; males slightly less likely to from birth to reproductive maturity sex chromosomes even. Xty share a small region of homology at the tips of their arms allows them to pair during meiosis. Chromosomes x - linked genes genes on x - chromosome show crisscross inheritance. Pattern males came only one copy of linked gene so recessive mutation. This allele can only be transmitted to a female in the next gem . Fz it can be transmitted back to a male basically it alternates blw sexes in successive generations most affected individuals are male heterozygous daughters of affected males can have affected sons offspring of. 8d can obviously the orientation of ohnmatrds can"t change in mitosis too they"ll already have been separated. Y - linked genes are transmitted from father to son to grandson genes in region of.
