The reason why there are seven classes and the number of ways that have an individual learned for classifying tetrads generally. Introduction: The use of tetrad analysis in modern genetics is based on the fact that any pair of allelic genes yields a division of 2:2 in tetrads. In some experiments, deviations from this division have been observed. When these deviations are infrequent, they may be detected and studied solely utilizing tetrad analysis.

Summary Introduction

To determine: The classifications that can be applied to both linear and unordered tetrads, also apply these classifications to the tetrads in this problem.

Introduction: Unordered tetrads require the presence of three genetic markers, and two of them must be different chromosomes to be able to calculate gene and centromere distances.

In a tetraploid B /B /b /b, how many quadrivalent possiblepairings are there? Draw them (see Figure 17-5).

Imagine that you have done a cross between two strains of yeast, one of which has the genotype A B C and the other a b c, where the letters refer to three closely linked genes in the order given. You examine many tetrads resulting from this cross, and the two tetrads below are found that have atypical scoring patterns. In tetrad I, the spores are A B C, ABC, a B c, and a b c. In tetrad II, the spores are A B C, A b c, a b C, and a b c. Which tetrad or tetrads indicate(s) that gene conversion has occurred AND show(s) that recombination has occurred between genes A and C? O neither tetrads I and II O tetrad II O tetrad I O both tetrads I and II
