Genes E, F, and D are linked in that order. The distance between D and E is 1 cM, and the distance between E and F is 0.6 cM. When the parental genotypes DdEeFf x ddeeff are crossed, which of these will be the resulting F1 recombinant genotypes?
A. DdeeFF
B. DdEeFf
C. ddEeFF
D. ddeeff
Homework Answers
Answer: Options A and C are correct
Explanation:
Gene order:
E---(0.6)---F--(0.4)--D
Parental cross: DdEeFf X ddeeff
Parental gametes: (DEF) (def) X (def)
Parental progeny: DdEeFf ddeeff
Other than these genotypes, all the remaining genotypes are recombinants.

Question 2 Genes a and b are linked, with 20% recombination frequency. Two pure breeding strains (the parental cross) were crossed. The F1 was then testcrossed. a+b-/a-b+ x a-b-/a-b- What were the parental strains genotypes? b. What would be the genotypes and the probability of each, among progeny of the testcross? Example: a+b+/a-b- 45% c. Is this an example of cis- or trans-linkage?

The following cross was carried out: BBdd x bbDD and all of the F1 offspring had the genotype BbDd. A) What are the possible gametes that these F1 offspring could produce? Put a circle around each type of gamete to make clear the alleles present in that gamete. B) If one of these F1 offspring is subjected to a testcross, which offspring genotypes would be considered recombinant and which offspring genotypes would be considered non-recombinant (parental). Make sure to indicate...

Which of these statements is incorrect? Syntenic genes are located on the same chromosome. Independent assortment results in recombinant chromosomes. You can reliably predict the relative genetic distance from genes’ physical distance on a chromosome. Linked genes are always syntenic. What is the relative genetic distance between two linked genes if the recombination frequency is 0.49? 0.49 cM 4.9 cM 49 cM 490 cM What statement best explains the distortion in Mendelian ratios observed by Bateson & Punnett in 1905?...
