Chapter 7, Problem 6LTB
Scientists have recently developed a process by which a skin cell from a human can be triggered to develop into a human heart muscle cell. This is possible because ___________.
- most cells in the human body contain the genetic instructions for making all types of human cells;
- a skin cell is produced when all genes in the cell are expressed; turning off some genes in the cell results in a heart cell;
- scientists can add new genes to old cells to make them take different forms;
- a skin cell expresses only recessive alleles, so it can be triggered to produce dominant heart cell alleles;
- it is easy to mutate the genes in skin cells to produce the alleles required for other cell type

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…
