1. On an autosome, genes A and B are twenty map units apart. An AABB male mates with an aabb female. What % of the gametes produced by their hybrid offspring will be Ab?
2. On an autosome, genes C and D are 10 map units apart. A CCID male mates with a ccID female. What % of the gametes produced by their hybrid offspring will be CD?
3. On an autosome, genes A and B are 10 map units apart. On another autosome, genes C and D are 20 map units apart. An AABBCCID male mates with an aabbccID female. What percent of the gametes produced by their hybrid offspring will be AbCd?
4. If two genes are linked, then the frequency of parental ditype tetrads resulting from a two-point testcross will be
5.From a three-point testcross mapping experiment, the following gamete data is obtained:
ABC 365; abc 367
aBc 110; AbC 105
aBC 4; Abc 3
ABc 25; abC 21
From the above data, what can be said of the genes?
