Exam 2: Mendelian Inheritance

Two heterozygous plants are bred. The enzyme that controls the phenotype that is being studied is measured in the progeny and represented in the graph below. What are the expected ratios of the different progeny based on their enzyme levels?

Mendel had experience in the fields of ________ and ________.

According to the Law of Segregation allele segregation into gametes is

The study of family trees in humans is called a ________ analysis.

Huntington's disease is a fatal syndrome caused by a mutation in the HD gene. The disease has an average age of onset of 35 and the majority of individuals that are affected are heterozygotes. What is the probability that a 25-year-old woman with no symptoms and who is the daughter of a man that has HD and a mother who does not will have a child that will have the mutant HD allele?

An individual who has two identical alleles for a trait is said to be ________.

Select which of the following results would most closely conform to a test cross of a dyhybrid plant

________ is the belief that seeds are produced by all parts of the body and transmitted to the next generation.

What was the conclusion from Mendel's two factor crosses?

Mendel's work with monohybrid crosses provided proof of which of the following?

What is a feature of a pedigree? Check all that apply.

An allele that produces an inactive enzyme would be classified as what kind of allele?

Polymerase chain reaction (PCR) can be used for many different purposes, including determining paternity. PCR amplifies specific DNA sequences from complex mixtures and can be used to amplify sequences that although they may not have any known function may have several unique sizes and these different forms are inherited according to the Law of Segregation. Below is a diagram of an agarose gel of PCR samples from a mother, and several children. Which letters represent children that could be biologically related to the mother?

If the progeny of a mating of pea plants have the following ratios 1342 smooth seed/green pod, 447 wrinkled seed/yellow pod, 429 smooth seed/ yellow pod, 1361 wrinkled seed/green pod what are the genotypes of the parents?

The Chi-square test is used to prove that a hypothesis is correct.

If a plant is test-crossed which of the following genes are linked?

Mendel's work was rediscovered in 1900 by which of the following individual(s)?

If an individual that phenotypically has dominant traits is mated to another individual that also has dominant traits and the progeny have both dominant and recessive traits it indicates that

A(an) ________ is a variation of a gene.

When Mendel crossed two plants that were heterozygous for a single trait, what was the phenotypic ratio of their offspring?
