Summary Introduction
To discuss:
The mechanism by which the immune cells distinguish between the good and bad bacteria.
Introduction:
One of the features of the immune system is distinguishing between self and foreign molecules. Cells of the body have major histocompatibility complex molecules (MHC class I) on their surface that present the various identification markers to cells of the immune system. Any cell displaying an alternative tag is destroyed by the immune system. There are histocompatibility complex molecules (MHC class II) on the surface of special cells such as dendritic cells that present external molecules to immune cells.

How many types of reactions can an enzyme perform?
Your goal is to produce black seeds resistant to mold. So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants.
Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold?
Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer.
Info from Question 4
a. P Locus (Seed Color):
Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus.
Observed Data:
Total white seeds: 45 (resistant plants) + 6 (susceptible plants) = 51
Total black seeds: 7 (resistant…

- Using Punnett Squares Punnett squares are one good way to predict the outcome of genetic crosses. Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. The number of possible alleles from each parent determines the number of rows and columns in the Punnett square. Independent Assortment KEY QUESTION How do alleles segregate when more than one gene is involved? Mendel wondered if the segregation of one pair of alleles affects another pair. For example, does the gene that determines the shape of a seed affect the gene for seed color? This type of experiment is known as a two-factor, or dihybrid, cross because it involves two different genes. Single-gene crosses are monohybrid crosses.

- 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…arrow_forwardLinkage in common bean Alleles at the P locus control seed color.
