Exam 18: Patterns of Inheritance

All of the following are true about this image EXCEPT:

Assuming a widow's peak is a dominant trait, the father would be __________.

This figure shows chromosomes lined up at the equator of the cell. Which stage of division does this represent?

Muscular dystrophy is a group of inherited disorders that lead to increasing muscle cell loss and thus muscle weakness over time. There are many different types of muscular dystrophy. Symptoms can vary, although all involve muscle weakness. Duchenne muscular dystrophy (DMD) is a recessive X-linked form that leads to muscle degeneration and death usually by age 25. Symptoms begin before age 5 and include low endurance and difficulties standing. As the condition progresses, muscle tissue is replaced with adipose and other types of connective tissue. Abnormal bone development and some neurobehavioral and learning disabilities may also occur. DMD occurs as a result of a mutation in a single gene on the X chromosome. This gene codes for a particular protein, dystrophin, which plays a major role in the structure of muscle cells. The protein formed by the mutated gene is nonfunctional, and the absence of a functional protein eventually leads to cell death. Bone and adipose are examples of __________.

Joshua is colorblind, but neither of his parents are colorblind. Which of the following is the most likely scenario?

Other types of muscular dystrophy arise due to mutations on chromosomes other than the sex chromosomes. The common name for these other chromosomes is __________.

The gene that codes for the number of fingers on the human hand has two alleles-five fingers and six fingers. The letters F and f are used to represent this trait. Having five fingers is the recessive trait. A woman has six fingers, but one of her parents has five fingers. She marries a man who has five fingers. Which of the following represents gametes that could be produced by the woman?

Assuming a cleft chin is dominant, the father's genotype would be __________.

Jack has type O blood and his mother has type A blood. His father could have any of the following blood types EXCEPT

Having five fingers is the recessive trait. A woman has six fingers, but one of her parents has five fingers. She marries a man who has five fingers. What is the probability that they will have a child who is homozygous dominant for this trait?

Domestication results from __________ selection, rather than __________ selection.

Green seed color is dominant over yellow seed color. What is the genotype of a plant that produces gametes with yellow seed color?

The single gene mutation associated with DMD leads to various symptoms that include bone growth, muscles, and behaviors. This is an example of __________.
