assignment baldness In man, a gender-influenced character is determined by two alleles in an autosomal locus. Allel B for baldness is dominant in men, but recessive in women. The alternative allele b is recessive in men, but dominant in women. In a large population (A) it turned out that 1% of the women were bald. Answer the following questions assuming that the population is in Hardy-Weinberg's balance with regard to the genetic system considered. a) Calculate the expected frequency of...

"The orange locus in cats is located on the X chromosome. In females, XoXo results in orange cats and X+X+ results in black cats When a female is heterozygous XoX+, they express both colors in patches due to a phenomenon called X-inactivation in which one X in every cell is inactivated. These females are called calico or tortoiseshell, depending on the presence of white spots. Male cats are either orange (XoY) or black (X+Y). A cross between a black female...
