The map of a chromosome interval is A-B = 20 m.u. and B-C = 30 m.u. B is in between A and C. If cross overs between A-B and B-C are independent events, how many double crossovers would be expected out of 1000 progeny from the cross ABC/abc × abc/abc?

When determining map distance between two genes that are far apart on the same chromosome, it is most accurate to add up the recombination frequencies of genes between the two outside genes because The recombination frequency between the two outside genes will be an over-estimate of the actual distance due to double cross-overs By adding up the smaller distances you can account for MANY of the double cross-overs that occurred between the two closest genes. By adding up the smaller...

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?

There are three genes - A, B, C - on the same chromosome. You have been studying gene A and know that the distance between A and B is 5 m.u. (map units), and the distance between A and C is 3 m.u. Based on the information you have, above, what are potential arrangements of all three genes on the chromosome? You can choose more than one. Note: answers give the genes and map units between them, in order. For...

Clamorosus, sordidus and manus parvus are recessive traits located on chromosome 3 in the newly-discovered diploid species electio vigintiviginti. The genetic map of this region is cl-8-s-10-mp. If you performed a test-cross between a fully heterozygous female and a fully homozygous male and observed 500 progeny, how many phenotypic classes of progeny would be expected and in what numbers?
