Mendel Hypothesized
Law of independent Assortment
alleles of one gene may be distributed to gametes independently of alleles for other genes
Genes on the same chromosome
Recombination
Sex determined sex chromosomes
Sex-linked genes found
Y chromosome carries
X chromosome carries
X genes have no counterpart on Y
X chromosome genes
Females of 2 X chromosomes
males only one X Chromosome
Y chromosomes contain
Mendelian Rules of Inheritance does not apply to all traits because
