Homework Answers
The genes G and B are located 14 map units apart. That means the
probability of cross over between them is 14%.
a. Genotype of F1 offspring.
parents : GB/GB x gb/gb
Gamete: GB x gb
F1: GB/gb
b. Gametes by F1.
Remember F1 cannot produce all combinations in equal frequency. The
genes G and B are linked, so only 14% will show recombination
between G and B. ALways there are two parental and two recombinant
types possible in 2 gene cross, so parenatl frequency will be
100-14 = 86; 86/2 = 43. The frequency of each recombinant will be
14/2 = 7%
The gametes will be:
GB - 43%
gb - 43%
Gb - 7%
gB - 7%
c. If ther F1 mate among themself, then the there is 7% chance of having a gamete with Gb genotype. In a cross two parents are invovled, so 7% x 7% - 0.49% chance of obtaining GGbb F2 offspring.

In flamingos, genes A and B are known to be 21 map units apart on chromosome #5. You mate an AA:BB male with an aa:bb female to produce F1 flamingos. a. What gametes will be made by these F1 individuals and in what proportions? b. When the F1's are bred to each other, they produce a total of 276 offspring. How many of these offspring would you predict should have the genotype Aa:BB?

27. An individual has the following genotype. Gene loci (A) and (B) are 15 map units apart, which determines their probability of recombination. 1) Indicate all the possible gametes that this individual can produce (with crossing over), 2) Label the gametes that are recombinant and non- recombinant. 3) Calculate the recombination frequency of the recombinant and non-recombinant gametes. The genes are not COMPLETELY linked. 28. Now imagine the genes are completed linked in #27. 1) What are all possible gametes?
