Exam 6: Patterns of Inheritance

Which of the following statements is NOT true?

Mendel used ________ as his research organism to study patterns of genetic inheritance.

Feather color in a certain species of bird is controlled by a pair of alleles that exhibit incomplete dominance. If birds that are homozygous for one allele are black and birds that are homozygous for the other allele are white, then heterozygous birds would be

A Punnett square charts the separation of alleles into ________.

Match each mode of inheritance to a statement listed below. -A human's ability to roll their tongue is dependent on a single gene that is either dominant or recessive.

A Punnett square is used to

In a particular plant, two genes control leaf shape and color. Round leaves (R) are dominant to jagged leaves (r). Yellow fruits (Y) are dominant to white fruits (y). A true-breeding round-leaved, yellow-fruited plant is mated with a jagged-leaved, white-fruited plant. What are the genotypes of the plants involved in this cross?

The genetic makeup of an organism, such as Gg, is its ________.

Which of the following might explain how two separate genes control a single trait?

Most traits in humans involve complex inheritance where the trait is governed by the action of more than one ________.

Two genes control fur color in Labrador retrievers. The first gene determines whether the pigment to be deposited in the hairs will be black or brown. The second gene determines whether the pigments are put into the dog's hairs at all. A dog homozygous for the recessive allele of this second gene will be yellow because no pigment is deposited in its hairs. This is an example of

The figure shown indicates two Labrador retrievers that are both homozygous recessive for fur color. Why is one dog brown and the other is yellow?

Which of the following expresses Mendel's law of segregation?

A pea plant that is heterozygous for the flower color gene makes gametes. What is the probability that a specific gamete contains the recessive allele for flower color?

Match each mode of inheritance to a statement listed below. -The color of wheat kernels is controlled by the interaction of two separate genes with one gene affecting the expression of the other gene.

In the Punnett square shown below, the lettered circles on the top and left of the square (indicated by the arrows) represent the

We need a hammer to pound nails into a board. Even if we have the nails, we cannot pound them without first getting hold of a hammer. This is similar to the genetic relationship known as

If you were a scientist studying patterns of inheritance in dogs and you were given extensive information about the inheritance of multiple physical traits, such as hair color and height, would you be able to piece together the entire genome of dogs? Explain your answer.

A dihybrid cross of fruit flies is used to examine inheritance patterns for eye color (black or white) and head shape (round or elongated). This cross produces 10,000 offspring, and the ratio is 1 (black eyes, round head): 1 (black eyes, elongated head): 1 (white eyes, round head): 1 (white eyes, elongated head). Is this what you would expect from a dihybrid cross? Explain your answer.

Would it be necessary to have both the genotype and phenotype for an organism if you are attempting to predict the inheritance pattern for a trait, such as hair color, in offpsring?
