Summary Introduction

To review:

Evolutionary development in the human populations immune to Plasmodium vivax due to the presence of a mutated enhancer for the glycoprotein present on their red blood corpuscles (RBCs).

Introduction:

A protist named P. vivax is mainly responsible for causing malaria. It gets attached to the RBCs after entering the blood. It has been found that some human populations in Africa are immune to P. vivax due to the absence of this particular glycoprotein on their RBCs. The transcription of this glycoprotein is influenced by the enhancers in a variety of tissues. In individuals immune to this form of malaria, the enhancer that is normally expressed in RBC precursors is mutated.

H gene assorts independently from the I gene. Both on autosomes. One man and one woman, both of HhIAIB genotype. Determine the blood type of progeny and fractions out of 16
Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
