It results in a short, crooked tail. A genotype consists of the genes in an organism. The F1 flies individual (both male and female) were all red-eyed, indicating that white eye color is recessive to the normal red eye color. The eye colour in Drosophila is sex linked and allele is present on X chromosome. The females were all red eyed whereas 50% males were white eyed and the remaining 50% males were red eyed (Fig. white, abbreviated w, was the first sex-linked mutation discovered, found in the fruit fly Drosophila melanogaster.In 1910 Thomas Hunt Morgan and Lilian Vaughan Morgan collected a single male white-eyed mutant from a population of Drosophila melanogaster fruit flies, which usually have dark brick red compound eyes.Upon crossing this male with wild-type female flies, they found … Performing the first reciprocal cross: a true-breeding red-eyed female (homozygous dominant) with a true-breeding white-eyed male (hemizygous recessive) results in an F1 generation comprised entirely of red-eyed individuals. Thus red eye is a dominant trait. On the other hand if a homozygous white eyed female (ww) is crossed with red eyed male (W) [Fig. This results from non-separation of two homologous X chromosomes during anaphase I of meiosis. Eye colour in fruitfly is a sex-linked trait and the cross between white-eyed female and red-eyed male gives red-eyed females and white-eyed males.

As expected, given Mendel's laws of dominant and recessive alleles, the first generation (the first filial, or F 1 ) comprised entirely red-eyed flies, the expectation if Red were dominant to White. Cross between red-eyed female and white-eyed male 5.43 (b)] in F 1 generation only the females are red eyed (Ww) having received a (W) carrying X chromosome from the male parent and a (w) carrying X chromosome from female parent. Feb 01,2021 - A cross between white eyed female and red eyed male Drosophila gives rise red eyed females and white eyed male. This would also confirm that the gene is specifically x-linked because white-eyed females could then only be produced in crosses with white-eyed males. What are the genotypes of each parent? Reciprocal cross- red eyed male (Xw+ Y) and white eyed female (Xw Xw) A surprising result was obtained when the reciprocal cross was performed by mating white eyed females to red eyed males.

Show the cross of a white eyed female X r X r with a red-eyed male X R Y . I Red eyes are dominant over white eyes. It is our belief that we had likely contamination by a white-eyed female which gave us the two different male phenotypes. Among thousands of such “regular” offspring, there are occasionally found exceptional white-eyed females and red-eyed males. 2. In the F 2, when these females were crossed to a red-eyed male, all of the female offspring receive the dominant "Red" allele from the male parent and are therefore red-eyed, whereas half of the male offspring receive from their female parent an X chromosome with the "Red" allele and would be red-eyed, and half an X chromosome with the "White" allele and would be white-eyed. Analyze the above observation and compare with the Mendelian dihybrid cross. All of the females will have red eyes; half of the males will have red eyes, and half of the males will have white eyes. 1) red-eyed females and white-eyed males 2) white-eyed females and red-eyed males 3) all red-eyed females and a 50:50 mixture of white-eyed and red-eyed males 4) all red-eyed males and a 50:50 mixture of white-eyed and red-eyed females 5) The result cannot be predicted because it depends on whether the female is homozygous or heterozygous Use a Punnett square to determine the possible offspring for a cross between a white eyed female and a red eyed male.

When Bridges Crossed White-eyed Females With Red-eyed Males, He Obtained A Few Red-eyed Males And White-eyed Females (see Figure 4.13). A white-eyed female fruit fly is crossed with a red-eyed male. Morgan, when experimenting, reported the sudden appearance of one white-eyed male (mutant form) in the culture of normal red-eyed Drosophila. It is similar to test cross where hybrids are cross bred with recessive parents. white eyed, female _____ red eyed, male _____ 3. All of the females and all of the males will have red eyes. However, cross a homozygous white eyed female with a red eyed male, and the unexpected results show all the males have white eyes and all the females red eyes. Thus a red eyed heterozygous female (XR Xr) will produce two types of gametes XR and Xr while the white eyed male (Xr Y) will produce two gametes ie Xr and Y. In a cross between a white-eyed female (ww) and a red-eyed male (w+Y), nearly all the progeny were either red-eyed females (w+w) or white-eyed males (wY). have white eyes. The females were all red eyed whereas 50% males were white eyed and the remaining 50% males were red eyed (Fig. When the reciprocal cross of white-eyed females and red-eyed males is performed, if the red phenotype is dominant, all of the females would be red and all of the males would be white. Cross 1: Morgan mated this white eyed male with a wild type red eyed female.All 1237 offspring of this cross had red eyes. Thus red eye is a dominant trait.   (think about the percentage of the total #) bei 6. Show the cross of a white eyed female X r X r with a red-eyed male X R Y.
