ANSWER - b, 1/4

EXPLANATION

while eyed male Redeged female x x x I hed eljed female ( 1 ), while eyed female ( 7 ) I had esed male (X4) and 1 While eied

Let XW+XW be the genotype of female parent having red eyed phenotype and XW+Y be the genotype of male parent having white eyed phenotype.

When the parents are mated, 1/2 of the resulting offsprings will have red eyes and of them, half will female and half will male offsprings.

That is, 1/4 of the offsprings will be male having red eyes (genotype - XWY).

    Fruit flies normally have dull red eyes. Some fruit flies have white eyes due to 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 white-eyed female (mutant phenotype) mates with a red-eyed male (normal or wild- type phenotype), what is the likelihood that their female offspring will have red eyes? Parents: white-eyed female X red-eyed male Select one: a. O...

    Birds normally have dull red eyes. Some birds 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 birds are: females, normally XX; males, normally XY. Part 1) 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?

    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.

    Required information Fruit flies normally have red eyes. Seven different true-breeding strains of fly with white eyes have been identified (A-G). In each strain, the white eye trait is due to an autosomal recessive allele. It is possible all seven strains have mutations in the same gene. Alternatively, they may have mutations in different genes. To determine how many genes are involved in eye color in these flies, pair-wise crosses are performed between each strain. The offspring phenotypes resulting from...

    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

    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...

    Some fruit flies have an autosomal mutation that causes the recessive white-eyes to appear compared to the wild-type (dominant) red eyes, while others have an X-linked mutation that causes the same varieties. You are presented with two populations of flies in unmarked tubes: one that has the autosomal white-eye mutation, and a population that has the X-linked mutation for white-eye. Assuming you have separated the pure breeding red and white-eyed parents in each population, What is the set of two...

    3. In humans, Duchenne muscular dystrophy (DMD) is a disease where muscles become weaker over time. The gene is located on the X chromosome and is recessive. Those afflicted with this disease usually die in childhood. If a female is a carrier for DMD, what percentage of her sons will inherit the disease? What percentage of her daughters will inherit the disease? 4. Eye color in fruit flies is sex linked, with the recessive allele causing white eyes. Show the...

    Female fruit flies typically have two X chromosomes; male fruit flies typically have one X and one Y chromosome. They have other chromosomes too that are NOT sex chromosomes. Suppose there is a gene in fruit flies that influences the hairs a fly has on its thorax (the middle section of its body). A recessive allele of this gene causes the hairs to be very thick, while a dominant allele causes the hairs to be very thin. Suppose a heterozygous...
