Polygenic Inheritance

Mama Isabella has a blood type of O. Her son, Norman, has also a blood type of O. What is the blood type of Norman's father?

In humans, the gene for curly hair (H) is incompletely dominant to the gene for straight hair (h). Individuals that are heterozygous (Hh) have wavy hair.

Two wavy-haired heterozygous parents have a child.

What is the likeliness that the child will have wavy hair?

Australian Shepherds are a breed of dogs whose coat color is directly impacted by two different genes. The gene that determines basic coat color exhibits a dominant allele (B) for black coat color and a recessive allele (b) for red coat color. Additionally, these dogs can have a solid coat color (mm) or a mixed pattern coat color called merle (Mm). The homozygous dominant coat color is called a lethal white (MM) which produces pups that are deaf and blind. What is the probability that two red Australian shepherds will produce a black pup?

Colorblindness is a sex-linked recessive disorder. If the daughter of a couple is colorblind, what are the two possible genotypes of her mother?

X^AX^A and X^AX^a

X^AX^A and X^aX^a

X^AX^a and X^aX^a

Cannot be determined

13.

If a trait shows up more commonly in men than women it is probably

not inherited

on the x chromosome and dominant

on the x chromosome and recessive

on a normal body chromosome

14.

Vitamin D resistant rickets (deformed bone formation) is a sex-linked DOMINANT trait. According to the Punnett square, what percentage of female offspring will have the disorder?

25%

50%

15.

The sex of a child is determined by

whether the father's sperm contains an x or y chromosome

whether the mother's egg contains an x or y chromosome

the age of the parents

16.

Why is the gene for a disease or disorder more likely to be found on the X chromosome than Y?

The X chromosome has many more genes

The Y chromosome has many more genes

17.

Males are more likely to suffer from a sex-linked disease or disorder because

males are the weaker sex

males have less DNA

males have 1 X chromosome, so the disorder is more likely to be expressed

18.
