The following cross was carried out: BBdd x bbDD and all of the F1 offspring had the genotype BbDd. A) What are the possible gametes that these F1 offspring could produce? Put a circle around each type of gamete to make clear the alleles present in that gamete. B) If one of these F1 offspring is subjected to a testcross, which offspring genotypes would be considered recombinant and which offspring genotypes would be considered non-recombinant (parental). Make sure to indicate the possible genotypes from this cross and label each genotype with either recombinant or nonrecombinant. C) What results among the F1 offspring would indicate that the B and D genes are linked?

2. You carry out a dihybrid cross in sweet peas where you examine the flower color locus (use symbols based on "P" for this gene) and blooming time locus (use symbols based on "L" for this gene). You cross a true breeding purple- flowering, early blooming plant to a true breeding red-flowering, late blooming plant. The F1 plants are all purple- flowering and late blooming. The F1 plants were subsequently used in a testcross. The flower color locus and the...

4. Now, assume that a F1 male and a F1 female offspring produced by the cross in #3 above mate with each other. F1 offspring : XXGgBb and XYGgBb Note: You can ignore the X and Y chromosomes here in question 4. Why? The traits of interest (fire-breathing and laser-shooting) are autosomal, so the sex of the fly (XX=female or XY=male) will not impact the trait expressed. You only need to follow the inheritance of chromosomes 2 and 3 for...

The results for the F2 progeny are shown for a F1 cross using
the two X-linked markers:
w+ and m+.
As shown in the figure, the F1 cross is between the following
two parents:
- a phenotypically wild-type (red eye, full wing), heterozygous
female: w+m+/wm
- a double mutant male (white eye, miniature wing):
wm/Y
Answer the following questions:
1) In the F1 cross, can you infer the genotype for the phenotype
in the female? Why or why not?
