Exam 29: Heredity

A Punnett square is a diagram that may be used to figure out the possible combinations of genes for a trait.

Amy's hand was exposed to X rays. A gene in a skin cell of her hand mutated. This mutant gene will .

Hereditary characteristics are transmitted to offspring by genes.

Most genetic disorders are inherited through dominant genes.

Genetic segregation implies that the members of the allele pair determining each trait are distributed to different gametes during mitosis.

A woman has blond hair and brown eyes. This statement is best described as indicating .

Figure 29.2 Use Figure 29.2 to answer the following: -Are there any male carriers?

A female infant is born with several hundred oocytes, each one genetically unique. This is due to )

A chromosomal aberration in which part of a chromosome is lost is known as .

Among members of the Fuzzy Wuzzy tribe, we will consider two pairs of genes: F = fuzzy hair vs. f = straight hair, and T = long hair vs. t = short hair. A homozygous, straight- shorthaired male marries a homozygous, fuzzy- longhaired female (P1 generation). Their offspring (the F1 generation) intermarry and produce progeny (second generation) of four types: fuzzy- longhaired, fuzzy- shorthaired, straight- longhaired, and straight- shorthaired. The results follow a standard dihybrid pattern. -A cross of two second- generation, straight- shorthaired individuals would yield what phenotype?
