Submit your questions for the Midterm 2 Review Session. More than one question and more than one submission is allowed.

10/19/2021	57106047	Chapter 6 Questions 20 (part a, b) & 24 (part a, b) - How do we determine the compounds that are present in each selective media from the given tables, and how can we use that data to determine the gene order?
10/19/2021	57082215	It would be helpful if we could walk through the end of the Module 5 lecture notes, specifically the "mechanism of recombination" and the significance of the Holliday junction. Ch. 5 of the textbook didn't exactly cover this in the same way and I'm somewhat lost here.
10/19/2021	57057767	Tribybrid chromosomes and how to determine the gene order from the trihybrid
10/19/2021	57057673	Determine the gene order based on Hfr strains and the F plasmid insertion
10/18/2021	57051934	A question helping us learn how to read a stem loop structure Ex: "For questions 16 and 17, refer to the RNA molecule that forms a stem-loop structure as diagrammed below, with the horizontal line indicating the hydrogen bonds holding the stem together?"
10/18/2021	57051913	A question where you find the interference Ex: "The trihybrid is crossed with a tester (abt/abt), producing 1000 offspring. You observe five double recombinants. What is the interference?"
10/18/2021	57051888	Ok so there are 2 large questions I would like you to review, the one where you need to find the arrangement of all the alleles, gene order, and gene frequency. Ex: "For questions 33-36, refer to the following scenario. In rabbits, chocolate-colored fur (w+) is dominant to white fur (w), straight fur (c+) is dominant to curly fur (c), and long ear (s+) is dominant to short ear (s). The cross of a trihybrid rabbit with straight, chocolate-colored fur and long ears to a rabbit that has white, curly fur and short ears produces the following offspring (a genotype column is provided for your convenience). What is the arrangement of the alleles (not necessarily the order) for the three genes on the trihybrid chromosomes?" Another question I would like done is the one where you have to find the frequency between set genes Ex: "For questions 22-24, refer to a trihybrid whose genotype at three genes is Aa Bb Tt, as pictured below. What is the frequency of the genotype ABt among the gametes produced by the trihybrid?" Not necessary the example questions but ones like it.
10/18/2021	57047417	Red fruits (T-) is dominant to tangerine fruits (tt), and smooth leaf (H-) is dominant to hair leaf (hh). Suppose the recombination frequency between these genes is 16%. You take a pure-breeding plant with red fruits and smooth leaves and cross it with a pure-breeding plant with tangerine fruits and hairy leaves. You perform a test-cross with the F1 generation and produce 500 offspring. What is the approximate number of offspring for each possible phenotype?
10/16/2021	56913024	ch 6 problem 20a
10/14/2021	56789212	How do you get the F2 generation in a linkage detecting test cross as well?
