Exam 2: Transmission Genetics

The probability of experimental outcomes gets smaller toward the farthest left and right portions of the curve.The probability of a given observation compared to all possible outcomes is known as what?

What is the probability of rolling two six-sided dice and obtaining an odd number on at least one die?

Mendel performed many types of crosses,including those in which the same genotypes are crossed but the sexes of the parents are switched.These are known as

What genotypic ratio would you expect to see among the progeny of a monohybrid cross?

How many possible gametes can be produced by a short plant with yellow,round peas with a heterozygous genotype (YyRrSs)?

In peas,axial (A)flower position is dominant to terminal (a),and tall (L)is dominant to short (l).If a plant that is heterozygous for both traits is allowed to self-fertilize,how many of the offspring would also be heterozygous for both traits?

In 1997,a gene called Le was discovered by two research groups led by David Martin and Diane Lester.Allelic variation in the Le gene,which controls elongation of the plant stem between branches,is responsible for which trait in peas?

What is the probability of rolling one six-sided die and obtaining any number but 6?

How did the study of physics with Professors Doppler and Ettinghausen influence Mendel's understanding of genetics?

One key to Mendel's success was choosing to observe ________ traits,which exhibit one of two possible phenotypes.

The genes responsible for some of the traits that Mendel observed have been recently identified and have helped in determining how molecular variation produces morphologic variation in pea plants.Allelic variation in the Sbe1 gene,which produces starch-branching enzyme 1,is responsible for which trait in peas?

By convention,when the difference between the observed experimental outcomes and the expected outcome is less than 5 percent (< 0.05),the experimental results are considered to be

The statistical interpretation of a chi-square value is determined by identifying the P value for each experiment,and the P value is dependent on the number of degrees of freedom (df)in the experiment being examined.For the coin flip experiment,the df value is equal to 1.What would be the df value for the example about rolling a 1 in a single roll of a die?

What is the probability of rolling two six-sided dice and obtaining two 4s?

Geneticists must be able to compare the outcomes they obtain in their experiments to the outcomes that might be expected to occur.Which test would they use to confirm that the difference between observed and expected can be attributed to chance?

Describe the blending theory of heredity and how Mendel's results help to reject this theory.

What are Mendel's first and second laws,and what do they state?

A ratio of 9:3:3:1 is expected among the F₂ progeny of a dihybrid cross as a result of ________ of alleles at two loci.

In a dihybrid cross,you want to calculate the probability that an F₂ progeny of the cross will inherit both dominant phenotypes.Which of the rules of probability can be used to calculate the probability of obtaining that combination of alleles?

You have self-fertilized a plant with round seed that is heterozygous,and you want to determine what proportion of the offspring will be not only dominant,but true-breeding.Which of the rules of probability can be used to calculate the probability of obtaining a particular outcome when specific information about that outcome modifies the probability calculation?
