Question

Please show me how to do a problem like this?? How to determine the other offspring and their frequencies? I'm used to be given 8 offspring with frequencies for each. How do you do this style? 1) An individual heterozygous for d e f was crossed to a homozygous recessive individual ( d/d ele f/f). The following offspring were recovered. + e f d e f 39 372 47 412 What is the correct order of these genes? A. def B. edf 2) Which of the following maps showing order and map units is closest to correct? a) d 1 b) d 1 c) f 1 d) d 8 3) What is the closest value to the interference using map distances of 1 and 87 a) 0 c) 5 d) 1 e)

Explanation / Answer

1)

The order of alleles :def; Option A is correct. This is because the alleles d and + are at 412 map units, + and e at 5 map units and + and f at 7 map units.

2)

The map showing order and map units is closest to correct is d 1 e 8 f. Option a is correct.

3)

Closest value to theinterfeence using map distances 1 and 8 is 1. Option d is correct.

Frequency of allele + = 39/882 = 0.044

Frequency of allele e = 372/882 = 0.42

Frequency of allele f = 7/882 = 0.007

Frequency of allele d = 412/882 = 0.46
