10) What is/are the parental phenotypic type(s) you predict in
the F2 (progeny of the F1 cross)?
11) What is/are the recombinant type(s) you predict in the F2

12) Now that you can distinguish parental vs recombinant types,
you can calculate the recombination between w+ and m+:
write the fraction and calculate the recombination

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?
2)...

In Drosophila, alternate alleles of an X chromosome gene, white, determine red eyes (w') and white eyes (w). Alternate alleles of a second X chromosome gene, yellow, determine brown body ) and yellow body (). In cross series A and B, the F1 females are heterozygous for both genes, but the arrangement of alleles in the parental generation is different in each case.

A (w-/ w-) white-eyed Drosophila female is crossed with a red-eyed male. Assuming the trait for eye color is sex-linked, what are the possible phenotypes of the progeny? All red-eyed individuals Red- and white-eyed females and males Only red-eyed females and white-eyed males Both red- and white-eyed males and only white-eyed females None of these

B. Geneticists have discovered that some flies have white eyes and others red eyes. The difference in eye color is due to inheritance of one gene. Two true-breeding flies are mated, with the female white-eyed and the male red-eyed. The F1 are 1/2 red eyed and female, and 12 white-eyed and male. (There are no white-eyed females, or red- eyed males.) 11. The F2 includes: 54 red-eye females 42 white-eyed females 48 red-eyed males 56 white-eyed males Phenotypes d (o-edd/e...
