Question

12) In peas, the yellow seed color is dominant (YY or Yy) over the green seed color (vy). You have been given a plant that only produces yellow seeds and need to determine if the plant is YY or Yy. Which of the following crosses would be most effective for determining the genotype of your plant? A)your plant x a plant that produces only green seeds B)your plant x another plant with known genotype YY C)your plant x another plant with known genotype Yy D) No cross is necessary. You should just plant your yellow seed and see what color flowers it produces. E)There is no way to determine the genotype of your plant. 13) A pheasant breeder starts with two birds in the P generation, one of which is AA and the other is aa. If she takes two of the birds from the F, generation and breeds them together, what genotypes can she expect in her F2 offspring? A)AA and Aa B)Aa and aa C)AA, Aa, and an DAA only E)Aa only 14) An individual with a dominant phenotype is crossed with an individual with a recessive phenotype. Five out of nine offspring show the dominant phenotype. What is the genotype of the dominant parent? A)homozygous dominant B)heterozygous Chomozygous recessive D)either homozygous dominant or heterozygous E)There is not enough information to determine the genotype of the dominant parent. 15) Across that involves two traits is called a A)monohybrid cross. B)dihybrid cross. C)Punnett square. D)test cross. E)trihybrid cross. 16) When pairs of factors separate independently of other pairs of factors, this is known as A)the law of segregation. B)the law of independent assortment. C)the law of dominance. D)multiple alleles. E)codominance.
