Exam 10: Patterns of Inheritance

If one pair of genes could cause some flowers to have red petals or yellow petals and could also determine the strength of the stem, this would be an example of

When a gene has the ability to influence several different aspects of the phenotype of an organism, this is referred to as

A condition in which a diploid organism has different allelic forms of a particular gene is the definition of

In humans, the genes for blood type A and B show lack of dominance to one another and both dominate O. Two type O people would be able to have

If the parents of a child have the following genotypes [Bb * Bb], what is the probability that they will have a child with the genotype [BB]?

Which of the following does NOT express one of Mendel's laws?

In the cross AaBb * AaBb, ____ of the offspring will express ___.

A gene that can be masked by another gene is called

In humans, normal vision dominates color-deficiency, and both are X-linked. (The genes are located on the X chromosome.) A color-deficient male marries a woman who is heterozygous for normal vision. If they have a boy, the chance that he will be color-deficient is

In fruit flies, long wing (L) is dominant, vestigial wing (l) is recessive, gray body (G) is dominant, ebony body (g) is recessive. Two fruit flies were mated that were long-winged with gray bodies. The genotype of these two parental flies is LlGg * LlGg. What proportion of the offspring flies would have long wings and gray bodies?

"She is a carrier of the cystic fibrosis trait." This statement acknowledges that this person

"Two out of three times, they will pass on the trait." This is a statement of

A male has a genotype RrTt. What is the probability of his producing Rt sperm cells?

In a cross between two blue Andalusian chickens, 25% of the offspring produced were white, 25% where black, and 50% were blue Andalusian like the parents. Color in these chickens is most likely inherited by

In snapdragons, FR = red flowers and FW = white flowers. Plants heterozygous for flower color have pink flowers. A cross between two pink-flowered plants will produce ____ red-flowered plants.

"We are only going to trace this one trait from one generation to another." This statement would indicate that

Nearly two dozen different alleles for the same gene can determine eye color in fruit flies. This is an example of

In pea plants, smooth seeds (S) are dominant over wrinkled seeds (S). A cross is made between a wrinkled-seed variety and a heterozygous smooth-seed variety. The chance of getting offspring homozygous for smooth seeds is

Geneticists use this term when explaining how genetic information is converted into physical features of a cell or organism.

"She is a carrier of the cystic fibrosis trait." This statement acknowledges that this person is
