Are males or females are more often affected by sex-linked traits? Explain why.

Describe the XX-XO system of sex determination. In this system, which is the heterogametic sex and which is the homogametic sex?

Explain the difference between X-linked recessive traits and X-linked dominant traits. What are the possibilities that a female child will be affected and express each of the traits?

Explain the term heterogametic sex?

Which of the following statements is INCORRECT? Sex-limited traits affect a structure or process that is found in one sex but not in the other. Sex-influenced traits appear in both sexes. Expression of sex-influenced traits may differ between sexes because of hormonal differences. Pattern baldness is autosomal recessive in men, but autosomal dominant in women.   Which of the following statements is NOT TRUE of complete androgen insensitivity syndrome (CAIS)? There is loss of function of the X-linked AR gene specifying the androgen receptor in males. Affected males cannot produce testosterone. Affected males have external genitalia that assume the default female state. Persons with CAIS are externally female but sterile because they lack the internal duct systems of either sex.     Which of the following statements is INCORRECT? In human females, XX cells inactivate one of their two X chromosomes due to dosage compensation. About two weeks after fertilization, each cell…

Describe some characteristics of incomplete dominance, multiple allele inheritance, sex-linked inheritance, and provide examples for each

Compare and contrast the relationship between phenotype and genotype in sex-linked traits to the relationship between phenotype and genotype in autosomal traits.

If the frequency of the "green" form of red-green color blindness (due to an X-linked locus) is 5 percent among males, what fraction of females would be affected? Assuming H-W equilibrium what fraction of females would be heterozygous?

Explain the concept of incomplete dominance and codominance. Give example of how each is expressed
