Provide an explanationThree genes are linked: a---------------20----------------b----------10------------c In a trihybrid test cross, from which 1000 offspring are counted, how many double crossover offspring are expected if there is no crossover interference? How many would be expected if there was 20% (0.20) crossover interference? Question 8 A geneticist collects three-point test cross data to map three genes as follows: -----20----------------b--------10-------- cIn the test cross data, a total of 18 double crossover offspring were collected out of 1000 progeny. What is the number of DCO offspring that...

4. You are studying three genes in corn and performed a three-point cross. The three genes are green (V) vs Viniscent (V) seedlings, blue (Pr) vs red kernels (pr) and white (B ) or brown (bm) leaf midrib color. The table below list the offspring resulting from a testcross with a female F1 heterozygote. Type of gamete (NR, SCO, DCO Phenotype Progeny Gamete from F1 heterozygote Virescent seedling red 101 kernel Red kernel 175 Red kernel, brown midrib 259 Virescent...
There are three genes that you are tracking on a fruit fly: Gene ‘r’ that results in the phenotype of red body colour Gene ‘t’ for the phenotype of transparent wings Gene ‘b’ for the phenotype of black coloured eyes. You cross breed fruit flies with the above mentioned genes and observe the following: When red body fruit flies are cross bred with transparent winged fruit flies, 2400 offspring were produced. Out of the 2400 offspring,...
To draw a genetic map for three linked, recessive mutations for blowfish, rancid, spiny and toxic. You test triply heterozygous blowfish to toxic. The results are as follows: rancid spiny toxic r s t 1 rancid r + + 64 spiny + s + 84 rancid toxic r + t 96 toxic + + t 367 wild type + + + 4 spiny toxic + s t 46 rancid spiny r s + 338 total...
A series of two-point crosses among fruit flies is carried out between gees for brown eyes (bw), arc wings (a), vestigal wings (vg), ebony body color (e), and curved wings (cv). The following number of nonrecombinant and recombinant progeny were obtained from each crosss: Genes in cross Progeny (NR) Progeny (R) a, bw 2796 1434 a, cv 2102 305 a, e 3200 3200 a, vg 5172 2379 bw, cv 4614 1706 bw, e 4150 4150 bw, vg 2224 117 cv,...

8. (9 pts) A series of two-point crosses were carried out among six loci (a, b, c, d, e and f), producing the following recombination frequencies. The six loci map to three different linkage groups. Map the six loci, showing their linkage groups (you can use a single line for each linkage group), the order of the loci in each linkage group, and the distances between the loci of each group. If there is only one...
