Whether two genes are linked AND if each of the genes is on anlautosome or on the X-chromosome.Cc. Whether the wild-type or mutant allele of each gene is dominantAND if each of the genes is on an autosome or on the X-chromosome.d. Ifeach of the genes is on an autosome or on the X-chromosome.e. Whether the wild-type or mutant allele of each gene is dominantAND whether two genes are linked AND if each of the genes ison an autosome or on the X-chromosome.f.

.Certain forms of human color blindness are inherited as X-linkedrecessive traits. Hemizygous males are color-blind, but heterozygous females are not. However, heterozygous females sometimeshave partial color blindness.A. Discuss why heterozygous females may have partial color blindness.B. Doctors identified an unusual case in which a heterozygousfemale was color-blind in her right eye but had normal colorvision in her left eye. Explain how this might have occurred.
Cross C: Homozygote wild type flies (+/+) were crossed with white eye flies. The table shows the results for the F1 and F2 generations. White eye females Wild type females White eye males Wild type males 50 F1 phenotypes (observed) F2 phenotypes (observed) F2 - expected phenotypes 50 60 60 60 60 What does the F1 tell you about the trait? Is the gene on an autosome or sex chromosome? What was the genotypes of each parent, male and female? What are the genotypes of the F1 flies? The F1 were crossed with each other and the phenotypes found in F2 are shown in the table above. Are these results consistent with the F1 and your theory of inheritance of this gene? Do a X2 test to see if the observed numbers are consistent with your theory.

In this part, you will work out on X-linked traits. Remember that males have only one X chromosome and females have two. For X-linked recessive, use the following designations: XA= normal Xa= the trait (a genetic disease or abnormality) For X-linked dominant, use the following designations: XA= the trait (a genetic disease or abnormality) Xa= normal Determine if the pedigrees below can be for a trait that is X-linked recessive. Write the genotype next to the symbol for each person in the pedigree below. A. Is it possible that this pedigree is for an X-linked recessive trait? B. What can you conclude about the children of mothers affected with an X-linked recessive characteristic? C. What can you conclude about the father of an affected female?
The mode of inheritance of the auricular hypertrichous trait in the Brown family is clearly an instance of: Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. b d recessive inheritance with the females being carriers. dominant inheritance with the males being carriers. X-linked inheritance, which is being expressed in the males since they only have one X chromosome. Y-linked inheritance, which can never be passed on to females.
Mutant female: yellow body and purple eyes. Male: Normal Use: https://www.sciencecourseware.org/FlyLabJS/ Which mutant alleles are dominant? Which mutant alleles are recessive? Which mutant alleles are sex-linked? Which mutant alleles are autosomal? Can you tell at this point if the two genes are linked? Show the results of the dihybrid analysis. Are genes segregating independently? What is the evidence for or against this? Show the crosses you will use to obtain the mapping data. For the mapping crosses, Write out the crossing scheme and make a table of the results (ignore sex in this table, combine the male and female progeny). Identify the parental classes and the recombinant classes. For a 3-point cross, identify the double cross overs. Show your calculations for the recombination frequencies between the three genes (for the 3-point cross) or the two genes (for the two-point crosses).

What is a Barr body? How many Barr bodies in a person with genotype XXXXX? How is the structure of a Barr body different from that of other chromosomes in the cell? How does the structure of a Barr body affect gene expression? Color-blindness is an X-linked recessive trait. Heterozygous females are not color blind but they can sometimes have partial color blindness. Explain how this can occur.
If a Drosophila female that is homozygous for an X-linked recessive mutation is bred with a male that carries the corresponding wild- type allele, the offspring will show the mutant phenotype in all individuals. be uniform wild-type. show a phenotype intermediate to the parents' phenotype. show the mutant phenotype in all males and the wild-type phenotype in all females. have mutant and wild-type males and mutant and wild-type females.
Explain the difference between X-linked recessive traits and X-linked dominant traits. What are the possibilities that a female child will be affected and express each of the traits?
