Summary Introduction
To review:
The effect of training for a marathon on the number of muscle cells in the gastrocnemius.
Introduction:
Gastrocnemius is the muscle that forms the half of the calf muscles present on the back of the lower leg. The muscle fiber is a thin and long muscle cell. The muscle cell contains myofibrils that consist of repeated units of sarcomeres (alternating dark-light units). Regular workout results in the increase in overall length of sarcomeres.

- 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…arrow_forward10.

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.

- Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism.

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.
