- Answer ALL questions in the foolscap paper sheets. 1. In the fruit fly, Drosophila melanogaster, the gene for eye colour is sex linked. The allele for the red eve is dominant to the allele for white eye. In an experiment, a red-eyed female was crossed with a white-eyed male. Two fruit flies of the F1 generation were then crossed. The following F2 phenotypes were produced: red- eyed females red-eyed males white-eyed males 95 49 56 By using suitable symbols, draw a genetic cross diagram to explain the results.Question 51 How does an X-linked gene affect the inheritance pattern for a given trait?

- In fruit flies, the color of the eyes is sex linked (on the X chromosome). Complete the cross of the flies in the image to determine the possible offspring produced. Red eyes are dominant (R), White eyes are recessive (r). What percentage of the male offspring are expected to have red eyes?

A description of the alleles present in an individual at one or more loci. Example: MM or Mm or mm. Example: 11q1. 4-q2. 1", meaning it is on the long arm of chromosome 11, somewhere in the range from sub-band 4 of region 1 to sub-band 1 of region 2. Under a microscope, these look exactly the same. The centromere, banding, long arm, short arm, overall length, gene locations, and order of genes are exactly the same. However, nucleotide sequences in genes on the two chromosomes can differ. the unit of heredity, the sequence of nucleotides in the exon regions specifies the sequence of amino acids in a particular polypeptide Brown allele in eye color Red eye in fruit flies Ability to synthesize alcohol dehydrogenase…Which process creates recombinant chromosomes?

- State 3 important results of meiosis. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). TTT Arial ✓ 3 (12pt) ✓ T-E One parent cell undergoes mitosis, which results in the division of two identical daughter cells. Definition of primal Mitosis is the mechanism of reproduction in unicellular eukaryotes. For eukaryotes with many cells: Mitosis boosts cell production and promotes bodily growth and development.Damaged tissues or organs can be repaired by mitosis.Mitosis is a kind of reproduction for vegetative organisms that results in offspring with the same genotype as the parent.Question 26 refers to QTL on the cricket autosomes. Forthe sex chromosomes, females crickets are XX and malescrickets are XO, having just one X chromosome but noY chromosome. Can QTL for pulse rate be mapped oncricket X chromosomes?
