Question:

In a certain plant, a dominant allele for one gene
In a certain plant, a dominant allele for one gene, R, produces round fruit and the recessive allele, r, produces oblong fruit. A dominant allele of a second gene, Y, produces yellow flowers and the recessive allele, y, produces white flowers. The two genes are linked on chromosome IV. A plant ( ry / ry ) with normal chromosomes is crossed to a plant (R Y/R Y) homozygous for a reciprocal translocation between chromosomes IV and VIII. The presence of the translocation causes semi-sterility. The FI progeny are phenotypically yellow flowered with round fruit and are semi-sterile. A backcross to the parent with normal chromosomes yields the 750 progeny shown in the table below. From these data, draw a map showing all relevant map distances (in centimorgans) for the genes and the translocation breakpoint. Show your work.

Answers

The map distance is 22 cM can be calculated from the frequency of cross overs.

Here , Total gametes=381,

Yellow & Round=3, White & oblong=295, Yellow &oblong= 73, White & Round = 10.

We know, first two are normal gametes (as they are dominant and recessive) while the rest two are cross over gametes.

Therefore,

Frequency of the cross over gametes= number of crossover gametes divided by total number of gametes= 83/381 = 22 cM

Same way for semi-fertile,

Total gamete= 369

Frequency of crossover gamete= 82/369 = 22 cM
