Activity 4 Identification of phenotype of known genotype The characteristic of the color of the red tomato fruit (R) is dominant over the characteristic of the yellow color (r) The characteristic of the color of white flowers (W) is dominant over the characteristic of the color of the yellow flowers (w), and the characteristic length of the stem of the plant (T) is dominant over the short characteristic (t) If a red fruit plant with yellow and long-stemmed flowers is crossed, with anotheryellow, white-flowered and short-stemmed plant, knowing that the dominant characteristic is pure. What is the phenotype of individuals of the resulting generation?
Name Period Codominant Genetics # 1 1.In Andalusian chickens, B is the gene for black plumage. B' is the gene for white plumage. The genes show codominance. The heterozygous condition results in blue plumage. Show the crosses, Punnet squares, genotypic ratios and phenotypic ratios expected from the following crosses: a. black x blue X genotypic ratio- phenotypic ratio- b. blue x blue genotypic ratio- phenotypic ratio- c. blue x white genotypic ratio- phenotypic ratio- 2. In four-o'clocks, the genes for red flowers, R and white flowers, R' are codominant. The heterozygous condition results in pink flowers. A gardener crosses a red four- o'clock with a white one. What are the expected genotypes and phenotypes of the offspring ? Show the Punnet square and the cross. genotypes: phenotypes:
Q10. 1) What is meant by epistasis? The natural colouration of wild mice is called agouti and is produced from banded genes are involved, each with a dominant (A and B) and a recessive allele (a and b). The allele A codes for the ability to produce hair pigment: AA and Aa mice have pigmented hairs but all aa individuals are albinos. The Ballele codes for the ability to make hair with grduated colouration: BB and Bb mice have graduated hair, bb mice have hair that is all one colour which is black. hairs. Two MacBook Pro
