Exam 2: Mendelian Inheritance

Using Mendel's flower color (purple is dominant, white is recessive), if two heterozygous plants are crossed, what is the probability that the first two offspring will have purple flowers?

Which of the following traits was not studied by Mendel?

A coin is flipped 100 times, with a result of 53 heads and 47 tails. The deviation between the observed numbers and the expected 50-50 results is called ________.

The ________ indicates the probability that differences between the observed values and the expected values are due to random chance alone.

The theory of pangenesis was first proposed by ________.

Two dihybrid pea plants (both tall and with purple flowers) are mated. The cross resulted in 9866 progeny, of which 5550 were tall with purple flowers. What are the expected ratios of the other phenotypic classes?

Cystic fibrosis is caused by mutations in the CF gene, and there are several different mutations that are known to result in CF disease. The CF mutations behave as recessive alleles to the WT CF allele. If two carriers that have different mutations in their CF genes have children what is the probability that one of their children will have CF disease?

A true breeding line of green pod pea plants is crossed with a true-breeding line of yellow pod plants. All of their offspring have green pods. From this information, it can be stated that the green color is ________ to the yellow color.

If a Punnett square is used to visualize a three-factor cross (trihybrid cross) how many boxes would be inside of the square?

Differences in plant flower color or plant height are called a variant of a trait.

The ________ refers to the genetic composition of an individual.

The results of a dihybrid cross of plants is given in the table below. What conclusions would you make?

Statistical analysis determines the ________ between observed data and what was expected from the original hypothesis.

If two individuals with different distinct characteristics are mated, their offspring is called a ________.

The ________ is the observable characteristics of an individual.

Which of the following would be used to determine the probability of three independent events in order?

The anther represents the ________ portion of the plant, while the ovules represent the ________ portion of the plant.

A cross in which a researcher investigates the patterns of inheritance of a single trait is called a ________.

Which of the following is correct regarding the blending hypothesis of inheritance?

Mendel's work on inheritance had an immediate influence on the scientific community and theories of inheritance.
