3. In Manticores, the colour, of the wings can be White, Almond, Ochre or Jet. In separate crosses of true- breeding parents, we obtained the following data. P1 parents Jet x Almond Jet x Ochre Almond Ochre Fl offspring F2 offspring All Jet All Jet All Jet Cross 3/4 Jet; 1/4 Almond 3/4 Jet; 1/4 Ochre 9/16 Jet; 3/16 Ochre; 3/16 Almond; 1/16 White a. Based upon the data, how many genes control wing colour? Briefly explain your answer. b. For each gene(s), create symbols for the genes and alleles, and provide the P1 parent genotypes for each crosses (i-iii) above. 4. During the Summer at Hogwarts, Hagrid passes his time by breeding Hungarian Horntail dragons. When he bred together two black parents, he obtained yellow, black, and brown dragons in the ratio. 4 yellow 9 black: 3 brown. a. How many genes control colour in these dragons? Why? b. Use symbols to explain the phenotypes of the parents, and for each phenotypic category in the offspring. c. Dumbledore is especially fond of the brown variety. What is the probability that any single brown dragon will be true-breeding?Explanation / Answer
4.
a. The color of the dragons is controlled by two genes. Because the ratio is 9:3:4. It is recessive epistasis ratio. In recessive epistasis recessive allele of one gene locus mask the expression of another gene locus. For example The alleles of one locus expresses themselves only when the epistsstic locus has dominant alleles.
c. Only one that is bbyy
