Summary Introduction

To summarize: The proof that supports the fact that the “yup” locus acts as a pre-zygotic barrier to reproduction between two species of monkey flowers and whether the yup locus alone controls this barrier to reproduction.

Concept introduction:

Two species of monkey flower: Mimulus cardinalis and M. lewisii, which are closely related, will exhibit numerous pre and post-zygotic barrier to reproduction. But the pollinator of choice which is a prezygotic barrier accounts for the most of reproductive isolation.

How is the frequency of cotransduction related to the relative position of genes on a bacteial chromosome? Draw a map of three genes and describe the expected relationship of cotransduction frequencies to the map.
In the fish Species a, the expression of different combinations of four Hox genes results in structural differences in tissues and organs along the anterior-posterior axis. Figure 3 shows the expression pattern of four genes, i.e. Genes 1 – 4, and the tissue produced along the embryonic anterior - posterior plane of fish Species a wild type. The influence of Hox genes on the formation of specific types of tissue can be determined by introducing gain-of-function and loss-of-function mutations in specific Hox genes. Looking at Figure 3, predict what would happen to each one of the four types of tissues, if the expression of gene 3 was expanded anteriorly by a gain-of-function mutation so that the pattern of gene 3 expression would be the same as that of gene 2.
Can you answer both questions please (b) Based on the ABC model, what would be the predicted phenotype of a double AB mutant? (c) In developing flowers of dioecious Spinach and Thalictrum, stamens are not developed in female flowers, and carpels are not developed in male flowers. What is the simplest model of ABC class gene expression that might explain this?
