Your friend is convinced his calico cat is male. He takes the cat to the vet. Sure enough the cat is male but has a calico coat and is possibly infertile. How do you explain? Group of answer choices He is wrong, it's impossible to have a male calico cat The cat has three X chromosomes but no Y chromosome The cat has Kleinfelter's syndrome (XXY) and his two X's have different color alleles The cat is XYY and the two Y chromosomes are both expressed

Human females have two X chromosomes (XX); males have one X and one Y chromosome (XY). a. With respect to X-linked alleles, how many different types of gametes can a male produce? b. If a female is homozygous for an X-linked allele, how many types of gametes can she produce with respect to that allele? c. If a female is heterozygous for an X-linked allele, how many types of gametes can she produce with respect to that allele?
Morgan first suggested that theoriginal white-eyed male had two copies of the white-eye allele. Inthis problem, let’s assume that he meant the fly was XwYwinstead ofXw Y What crosses would need to be made to rule out the possibility thatthe Y chromosome carries a copy of the eye color gene?
What would be the sex of a human with each of the following numbersof sex chromosomes?A. XXXB. X (also denoted X0)C. XYYD. XXY
N: A cat is born with twoX chromosomes and one Y chromosome. This is a rare event. One ofthe X chromosomes carries the black allele and the other carries theorange allele. Would you expect this cat to be a male or female?Would it be calico?
Clark Kent and Lois Lane Kent are about to have a (Super) baby. As Superman, Clark possesses amazing traits, including heat-ray vision. Assume that this is: a) a dominant trait, and b) carried on the X chromosome. If Clark and Lois have a boy or a girl, what is the probability that they will possess their father's amazing abilities? (Remember: females have XX chromosomes, while males have XY chromosomes. The Y chromosome doesn’t carry any of the genes on the X chromosome). X H = Superman’s heat-ray vision allele on his X chromosome Y = Superman’s Y chromosome X h = Lois’s normal vision allele on her X chromosome
Because men only inherit one copy of the X chromosome they are said to be ______________ for geneitc traits located on the X chromosome.
Assuming (i) that the two chromosomes in everyhomologous pair carry different alleles of somegenes, and (ii) that no crossing-over takes place, howmany genetically different offspring could any onehuman couple potentially produce? Which of thesetwo assumptions (i or ii) is more realistic?

Hemophilia is an X-linked recessive disorder in humans. If a heterozygouswoman has children with an unaffected man, what are the probabilitiesthat she will have the following combinations of children? A. An affected sonB. Four unaffected offspring in a rowC. An unaffected daughter or sonD. Two out of five offspring that are affected
The X chromosome has a lot of traits for things besides the traits we consider female. It carries traits forthings like the ability of your blood to clot correctly and the ability to see differences in the colors red andgreen. If you blood doesn’t clot correctly, it’s called Hemophilia. If you can’t see the difference betweenred and green, you are colorblind. Therefore, these are referred to as X-Linked or Sex-Linked Traits.Notice that those are on the X chromosome only. That means they are missing from the Y. In fact, the Y iscalled Y because it is physically missing a section at the end. This means the Y chromosome is missing genes that the X chromosome has. If you are XY, you only haveone copy of the gene, or one allele. Given what we just said above, can a XY parent pass a X-Linked Trait to his XY offspring?
in the experiment of following chromosomal dna mvement througgh meiosis, why. do you use non-sister chromatids to demobstrate crossing over? what combinatiobns of alleles could result from a crossover between BD and bd chromosomes? Identify two ways that meiosis contributes to genetic recombination. Why is it necessary to reduce the number of chromosomes in gametes, but not in other cell?
Shown above is a family pedigree tree in which family members afflictedwith the disease Haemophilia are shown with filled-in squares (male) or circles (females). A couple is trying to determine the likelihood of passingon the disease to their future children (represented by the ? symbolabove) because the hemophilia runs in the woman’s family. Turner syndrome is a disease in which an individual is bornwith only a single X chromosome. Suppose the woman in thecouple is a carrier for hemophilia and has a child with Turnersyndrome. Would this child have the disease?
