If a crossover event happened in one half of all tetrads, how many recombinant gametes would be produced?
The answer is 25% but please explain.
Homework Answers
As during meiosis4 daughter cells are produced no mater what the recombinant are divided in to equal 4 part hence all the cell got there 25%

1. a) If one were to decrease the enzyme concentration by half, how would this affect the Vmaxvalue? Explain why this is so. What assumption are we making in regards to the relative amounts of substrate to enzyme? b) Is the turnover rate (kcat value) of an enzyme expected to change if the enzyme concentration was decreased by half? Briefly explain. c) Is the turnover rate (kcat value) of an enzyme expected to change in the presence of a competitive...

Given the genotype AaBbCcDdEE a) How many kinds of gametes can this individual form? b) If selfing occurred, what fraction of the progeny would have the following genotype: AaBBccDdEE? A cross between two plants produces progeny which, through subsequent breeding experiments, are shown to fall into 27 genotypic classes. Assuming that complete dominance operates at all of the loci involved and that each locus has two alleles, a) At how many different loci are the parents heterozygous? b) How many...

If only one water molecule were oxidized by PSII, how many photons of light would have to be absorbed and transformed into chemical energy? How many NADPHs would be produced at the other end of the light reaction, and where would the electrons and protons for the last step in the light reaction come from? Explain. In the same situation (one water oxidized), how many protons would accumulate, and where and how would they accumulate in support of making a...

Problem:
Yeast chromosome 3 has these genes in this order: HIS4 LYS1 URA3
ADE2. You have created a diploid strain of this genotype:
You sporulate the diploid and analyze tetrads. Most tetrads show
2:2 segregation for all markers and recombination frequencies that
are consistent with the established genetic map. However, you
notice the one strange tetrad indicated below:
Your goal is to explain how the genotypes of this tetrad arose
during meiosis:
a. Do these spores indicate that...

I'm having trouble understanding this problem. The most frequent
F2 progeny seem to have had crossover to me because the parents are
Aa Bb x aa bb but the progeny are Aa bb and aa Bb. I thought
parental progeny would have the same genotype as the parents. Can
you please explain how the most frequent progeny don't have
crossover? Thank you
