Consider the hypothetical sex-linked recessive baldness gene if a bald woman has a child with a normal male what are the odds their son will be bald?
Red-green color blindness is due to an X-linked recessive allele in humans. A widow's peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele. Consider the following family history: A man with a widow's peak and normal color vision marries a color-blind woman with a straight hairline .
*If a woman is bald she must have two copies of the recessive gene so she must pass one on to her children . Since her son would get his Y chromosome from his father and his X chromosome from his mother he would inherit her baldness gene .
The expression of one gene has no effect on the expression of another gene . The inheritance of one character has no effect on the inheritance of another character. Segregation of homologous chromosomes is random. There are two versions of each trait a dominant and a recessive; the one you get is random .
Red-green color blindness is a sex-linked recessive trait in humans. Two people with normal vision have a color-blind son . What are the genotypes of the parents?
- If a woman is bald she must have two copies of the recessive gene so she must pass one on to her children. Since her son would get his Y chromosome from his father and his X chromosome from his mother he would inherit her baldness gene . That means that all of her sons will be bald .
