- 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?In general, why do changes in chromosome structure or numbertend to affect an individual’s phenotype? Explain why somechanges in chromosome structure, such as reciprocal translocations,do not.Relate the characteristics of the Y chromosome
- Indicate the Chromosome Numbers, (NB: indicate the letter to correspondence chromosome Number) దా 8Explain the relationship between genetic and physical maps of a human chromosome.Assuming no other abnormalities, classify each of the following human sex chromosome complements as to whether or not individuals with that complement will be morphologically male or female. Three human sex chromosome complements will be classified as male and three will be classified as female. XXY XYY XXX XO XY XX
- Draw a Punnett square for the dihybrid cross. 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 polydactyly show no linkage.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?How many chromosomes are in a human karyotype?
