Question
Table 1. Group data of the entire class. My data is under Ashour and Jack.
QUESTION 1.
Calculate the distance between the tan gene and the centromere using the formula % recombinant progeny = distancegene-cent = ((1/2)(# SDS asci) / (total # asci)) *100
QUETION 2.
Did you observe any gene conversion? If yes, calculate the frequency of gene conversion events in your individual sample (data set) and the class data set.

In first coloumn the SDS and FDS is reversed in last coloumn. I have taken first column for data.
The answers
Question 1:
The Distance between gene and centromere = (1/2 X SDS)/Total progeny X 100.
SDS = 241
=
(1/2 X 241)/500 X 100 = 24.1
