In humans, as well as in many other animals and some plants, the sex of the individual is determined by sex chromosomes. The sex chromosomes are one pair of non-homologous chromosomes: XX represents a female, while XY represents a male. When a gene for a specific trait Is attached to the X or Y chromosome, we say it is sex-linked, and when it is attached to the X chromosome, we say it is X-linked. Alleles for these linked traits, such as hemophilia or color blindness, crosses, may be recessive or dominant. This is one possible cross (above) for the X-linked condition known as hemophilia. Which pair of parents is most likely to have a hemophiliac daughter? A) carrier mother and unaffected father B) carrier mother and hemophiliac father hemophiliac mother and a carrier father D) unaffected, non-carrier mother and hemophiliac father

If each gene is located on a specific chromosome and that chromosome has two pairs (homologous chromosomes), how does each chromosome represent one allele and why do you label each chromatid with the same allele?
Men have XY (or YX) chromosomes and women have XX chromosomes. X-linked recessive genetic diseases (such as juvenile retinoschisis) occur when there is a defective X chromosome that occurs without a paired X chromosome that is not defective. Represent a defective X chromosome with lowercase x, so a child with the xY or Yx pair of chromosomes will have the disease and a child with XX or XY or YX or xX or Xx will not have the disease. Each parent contributes one of the chromosomes to the child. Complete parts a through d below. a. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a son will inherit the disease? nothing (Type an integer or a decimal. Do not round.) b. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a daughter will inherit the disease? nothing (Type an integer or a decimal. Do not round.) c. If a mother has one defective x…
Human sex chromosomes are XX for females and XY for males. a. With respect to an X-linked gene, how many different types of gametes can a male produce? b. If a female is homozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele? c. If a female is heterozygous for an X-linked allele, how many different types of gametes can she produce with respect to this allele?
A company that offers PGD terms an embryo “normal and healthy” if it has 46 chromosomes. Why is this statement misleading? , Two famous male actors had twins using a surrogate mother who carried two embryos that hadbeen fertilized in vitro, one with one man’s sperm and the other with the other man’s sperm. In terms of genetics, how closely are the babies, a boy and a girl, related to each other if they have different fathers?
In fruit flies, eye color is carried on the X chromosome. The allele for red eyes is dominant over its recessive allele, white eyes. -Cross a heterozygous female to a white-eyed male 1st Question to answer ---- How many genotypes are possible among the offspring? 2nd Question to answer ---- How many phenotypes are possible among the offspring? 3rd Question to answer ---- What is the probability of getting a red-eyed male? 4th Question to answer ---- What is the probability of getting a white-eyed male? 5th Question to answer ---- What is the probability of getting a red-eyed female? 6th Question to answer ---- What is the probability of getting a white-eyed female? 7th Question to answer ---- What is the probability of getting a red-eyed offspring? 8th Question to answer ---- What is the probability of getting a white-eyed offspring?
In the classic "X" figure of the chromosome, is the whole X from one parent, or is one side of the X from the mother and the other side from the father?
Which of the following statements is false? Dosage compensation is accomplished in humans by stimulation of gene expression from the single X chromosome. Dosage compensation is accomplished in humans by inactivating a female X chomosome. An individual with Turner Syndrome has no Barr bodies. An individual with Klinefelter syndrome generally has one Barr body. A typical XX human female has one Barr body.
Genes that influence a given characteristic and arealigned with one another on a chromosome pair areknown as ___________.
Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___
You are studying a group of mutations in Drosophila all of which are recessive lethal and map to a small area of chromosome 3. You decide to perform complementation testing to see which mutations are in the same gene. You have bred your flies such that they have the following genotype: +; +; TM3 Sb/mut; + This indicates that chromosomes X, 2, and 4 are wild-type. One copy of chromosome 3 is the balancer TM3 Sb which carries a recessive lethal gene and the dominant marker Stubble (Sb), which causes the flies to have short bristles. The other copy of chromosome 3 carries your recessive lethal mutation. a) Describe how you would maintain each of your individual stocks. What ratios of phenotypes do you expect? b) When you perform your complementation testing, you will have to look at the F1 phenotypes to determine whether two genes complement. Describe what your F1 fly population should look like if the two mutations complement and if they do not. You breed each of your four…
Suppose genetic analysis reveals a serious mutation in a gene in the green region of the left-hand copy of chromosome 9 in this individual. Where would you go look for another allele of this gene in this individual to see whether this individual is homozygous or heterozygous for this mutation?
How many copies of a gene do you have... If you are a human male and the gene is on Chromosome 1? Why? If you are a human male and the gene is on the Y chromosome? Why? If you are a human female and the gene is on the X chromosome? Why? If you are an octoploid strawberry? Why? If you are a triploid banana? Why? If the population contains 13 different alleles of the gene, it is on Chromosome 1, and you are a human male? Why?
