Exam 2: Transmission Genetics

A couple has four children.What is the probability that they would have four boys?

The statistical value obtained from the chi-square analysis refers to the probability that the deviations of between the observed numbers and the expected numbers are caused by what?

The hereditary particles that are passed from one generation are called alleles in modern terminology.This term had not been invented in Mendel's time;instead,he determined that two "________" (alleles)were present for each trait in a plant and together determined the phenotype of the trait.

In peas,the round allele is dominant over the wrinkled allele.If a plant with round peas is crossed to a plant with wrinkled peas,all of the resulting plants have round peas.What is the genotype of the parents in this cross?

The law of independent assortment would predict that the F₂ progeny of F₁ heterozygous plants will exhibit a

The law of segregation states that the F₂ progeny of F₁ heterozygous plants will exhibit

Mendel performed numerous controlled genetic crosses to obtain strains that consistently produced a single phenotype without variation.What are these strains that consistently produce the same phenotype called?

When calculating the probability of a given genotype in a trihybrid cross,you can generate a Punnett square.Which of the rules of probability can be used to calculate the joint probability of simultaneous inheritance of multiple alleles?

A cross between a short pea plant and a tall pea plant results in a 1:1 genotypic and phenotypic ratio in the offspring.What are the genotypes of the parent plants?

The statistical interpretation of a chi-square value is determined by identifying the
