An individual comes into your genetics clinic to be tested for any anomalies. When looking at their karyotype, you notice they have three X chromosomes and a Y chromosome. What information would you be able to relay to this individual? O They have Turner syndrome, are genetically female, and have two Barr bodies per cell. O They have Klinefelter syndrome, are genetically female, and have two Barr bodies per cell. O They have Klinefelter syndrome, are genetically male, and have two Barr bodies per cell. O They have Klinefelter syndrome, are genetically male, and have three Barr bodies per cell. O They have Turner syndrome, are genetically male, and have three Barr bodies per cell.

A woman who sought genetic counseling is found to be heterozygousfor a chromosomal rearrangement between the second andthird chromosomes. Her chromosomes, compared to those in anormal karyotype, are diagrammed on the next page:(a) What kind of chromosomal aberration is shown?
Let’s say there is an organism with two pairs of alleles, W/w and Z/z, each pair is located on a different pair of chromosomes in the organism’s somatic cells. During Prophase, what will you observe in the somatic cells?
Let’s say there is an organism with two pairs of alleles, W/w and Z/z, each pair is located on a different pair of chromosomes in the organism’s somatic cells. During Metaphase, what will you observe in the somatic cells?
While working in the lab, you notice that your fruit flies all appear to have an intersex phenotype. This is most likely due to: O There being a 2:3 ratio of X chromosomes to autosomal chromosomes. O There being a 1:2 ratio of X chromosomes to autosomal chromosomes. O There being a 3:2 ratio of X chromosomes to autosomal chromosomes. O There being a 1:1 ratio of X chromosomes to autosomal chromosomes. O There being a 1:2 ratio of Y chromosomes to autosomal chromosomes.
A couple planning their family are aware that through the past three generations on the husband’s side a substantial number of stillbirths have occurred and several malformed babies were born who died early in childhood. The wife has studied genetics and urges her husband to visit a genetic counseling clinic, where a complete karyotype-banding analysis is performed. Although the tests show that he has a normal complement of 46 chromosomes, banding analysis reveals that one member of the chromosome 1 pair (in group A) contains an inversion covering 70 percent of its length. The homolog of chromosome 1 and all other chromosomes show the normal banding sequence. (a) How would you explain the high incidence of past stillbirths? (b) What can you predict about the probability of abnormality/ normality of their future children? (c) Would you advise the woman that she will have to bring each pregnancy to term to determine whether the fetus is normal? If not, what else can you suggest?
Draw a Punnett square for the dihybrid cross described below (it is the same story as given for question 8, above) and use it to fill in the blanks correctly in the text that follows. NOTE: Please type in whole numbers, no symbols. There are two known alleles of gene occupying a specific locus in the X chromosome. The gene in question codes for a transcription factor involved in digit development. The mutant allele is dominant and gives rise to an additional but non-functioning little finger (polydactyly) on both hands. A couple have had their DNA sequenced at the region of interest, the male exhibits polydactyly because of the mutation, the female is homozygous wild type at the same locus and therefore has the wild type phenotype. Both have green eyes. In this story; eye colour shows a monogenic autosomal inheritance pattern and the allele for brown eyes shows incomplete dominance with that for blue eyes, the heterozygote phenotype is green eyes. The genes for eye colour and…

During a practical, a group of biology students are tasked to study the cell cycle of an insect. This insect has the karyotype 2n=6, with genotype Ff Gg Hh KK. The students must draw a cell at the end of telophase of mitosis, using red lines for maternal chromosomes, blue lines for paternal chromosomes and black dots to represent centromeres. The drawing provided by the students is shown below. kt a) Identify three mistakes the students made when producing this diagram. In your answer only refer to elements already present in the figure. b) This fly is used in a testcross. What is the probability of producing a fly with genotype ff Gg hh Kk?
