A white eyes female fruit fly is mated to a red eyed (wild type) male. While most of their progeny are as expected, occasionally a white eyed female is produced due to nondisjunction in the female. What is the likely karyotype of this white eyed daughter? (assume all fruit flies have AA as autosomes)!!
(Please explain :) )
A) XX
B) XXY
C) XO
D) XXX
Y) XYY
Homework Answers
If non disjunction occur , one Chromosome pair will have extra copy while other chromosome will lack one chromosome .XXX- metafemale
XO- metamale or sterile male
XXY- normal female
XX- normal female
Since , XXY will be able to form normal female and show non disjunction condition . It will be the karyotype for the white eyes fruit fly.

Fruit flies normally have dull red eyes. Some fruit flies have white eyes due to a mutation in a gene on the X-chromosome. The white eyed phenotype is X-linked recessive. The sex chromosomes in fruit flies are: females, normally XX; males, normally XY. If a red-eyed female who is a carrier of the white eyed allele (normal or wild-type phenotype) mates with a white-eyed male (mutant phenotype), what is the likelihood that their male offspring will have red eyes? Parents:...

If an apterous female fruit fly with wild type (+) red eyes is crossed with a white eyed male with normal wild type wings, what is the resting F1 generation? Please show on a punnet square.Also what is the punnet dihybrid cross for the F2 generation. Note: the recessive white eyed allele is X-linked while the apterous (wingless) recessive allele is NOT x-linked. SO to summarize: male with recessive white eyes and with normal wild type wings and a recessive...

29, In fruit flies, red eyes are dominant over white eyes. The gene for eye color (R) is found on the X chromosome (X^R). Females have 2 X chromosomes and males are XY. Fill in the following (case sensitive!): Genotype of a white eyed female: Possible female gametes; separate gametes with a comma (,): Genotype of a red eyed male: Possible male gametes; separate gametes with a comma (,): In fruit flies, red eyes are dominant over white eyes.

A red-eyed male fly was crossed with a male whale with white eyes. The following offspring were observed: 90 females with red eyes 43 males with red eyes 47 males with white eyes Which statement is most accurate? a) We have polygen legacy b) The gene shows the 3: 1 ratio in monohybrid crossing c) The red-eye gene must be attached to the X-chromosome d) The white- eye gene must be attached to the Y-chromosome e) Females can never have...
