- What is the high-frequency alleles of a polymorphic gene?. If the frequency of the homozygous recessive genotype is 0.81, what is the frequency of the recessive allele?n guinea pigs, an allele for rough fur (R) is dominant over an allele for smooth fur (r), and an allele for black coat (B) is dominant over an allele for white fur (b). What would be the genotype of a guinea pig with smooth black fur? *
- Which allele is an example of a loss-of-function allele?In guinea pigs, an allele for rough fur (R) is dominant over an allele for smooth fur (r), and an allele for black coat (B) is dominant over an allele for white fur (b). What would be the genotype of a guinea pig with smooth black fur?For sex-linked recessive traits, only females can be “carriers”, like how both Diana and Olivia are carriers for hemophilia. Why can’t males be carriers for these traits?
- In humans, red–green color blindness is an X-linked recessive trait. If a man with normal vision and a color-blind woman have a son, what is the chance that the son will be colorblind? What is the chance that a daughter will be color-blind?Why are lethal dominant genes much more rare than lethal recessive genes?In humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed. if blue is recessive, what must the woman’s genotype be?
- Why are phenotypes the product of both their genes and their environments?In the image a Brown coated horse is crossed to a White coated horse and the resulting offspring has a Palomino coat. What Genetic characteristic causes this offspring coat color?In flies, small wings are recessive to normal wings. If a cross between two flies produces 8 small-wing offspring and 28 normal-wing offspring, what are the most likely genotypes of the parents? (Use SS to represent the normal-wing allele and ss to represent the short-wing allele.)
