Homework Answers
Recombination frequency is a measure of distance between genes here recombination frequency between C and D is 50% so let`s put C and D at the ends then B-D= 30% and D to F is 10% and C to F is 46% so F is far from C so it is 10 mu from D and B is 20 mu from F

Multiple choice: The measured distance between genes D and E in a two-point testcross is 50 map units. Where are genes D and E in relation to each other? D and E are on different homologous chromosomes. D and E are on the same chromosome, at least 50 map units apart. D and E are on the same chromosome, exactly 50 map units apart. D and E are on the same chromosome, less than 50 map units apart. A) 1...

5. You started working in a Drospohila lab. You are studying two different autosomal traits, body color and antennae length. Gray body (B) is completely dominant to black body (b) and long antennae length (A) is completely dominant to short antennae length (a). You cross true-breeding gray bodied, long antennae files to true-breeding black bodied, short antennae. The F1 progeny all have gray bodies and long antennae. a. You perform a testcross to the F1 progeny produced from the parent...

(9 points) You are interested in studying recombination frequencies in wasps. You identify a queen that is heterozygous at three different loci on chromosome 5: G, H, and R. As queen wasps can produce haploid male offspring without fertilizing their eggs, you decide to look only at the genotypes of her male offspring in your analysis. Below is a list of the genotypes of her male offspring, and the number of individuals that fall into each genotypic class. 92 168...

Which statement explains why the recombination frequency between two genes is always less than 50%? Recombination cannot be more than 50% because chromosomes are only 50 map units in length. The genotype of the F, gametes will always be 50% parental gametes and 50% recombinant gametes. Genes with a recombination frequency near 50% are unlinked and have an equal likelihood of being inherited together or separately. F1 gametes always have 50% of their alleles from each parental...
