question 20

Multiple Choice

Please use the following information to answer the question(s) below.
A plantlike organism on the planet Pandora can have three recessive genetic traits: bluish leaves, due to an allele (a) of gene A; a feathered stem, due to an allele (b) of gene B; and hollow roots due to an allele (c) of gene C. The three genes are linked and recombine.
A geneticist did a testcross with an organism that had been found to be heterozygous for the three recessive traits and was able to identify progeny of the phenotypic distribution (+ = wild type) shown in Figure 12.3. Figure 12.3
-If recombination frequency is equal to distance in map units, what is the approximate distance between genes A and B?

• A) 1.5 map units
• B) 3 map units
• C) 6 map units
• D) 15 map units
• E) 30 map units

Definitions:

F-statistic

A ratio used in statistical analysis to determine if the variances between two populations are significantly different.

F-test Statistic

A ratio of two variances that follows an F-distribution, used to compare sample variances and test hypotheses about the equality of population variances.

Regression Equation

An equation that predicts a dependent variable based on one or more independent variables, typically in the form Y = a + bX for simple linear regression.

Independent Variables

Variables in a statistical model that are manipulated or controlled to test their effect on dependent variables.
