Question
y of inheritance, which explains the underlying basis of 67. In 1902, Mendel's laws. A) Charles Darwin proposed the chromosome t 8) August Weissman C) Gregor Mendel D) Thomas Hunt Mor E) Walter Sutton 68. In genetic crosses the F in Fi n stands for: A) Familial B) Familiar D) Father E) none of the above 69. What are the expected phenotypic proportions in the progeny of the following cross, assuming that both genes are independent and T is dominant over t and G is dominant overg? GgTt x GgTt (gene G encodes trait 1; gene T encodes trait 2) ominant for both traits 1 and 2: 1 recessive for both traits 1 and 2 9 recessive for both traits: 3 dominant for trait 1 and recessive for trait 2:3 recessive for trait 1 and dominant for trait 2:1 dominant for both traits 1 and 2 dominant for trait 2: 1 recessive for both traits 1 and 2 dominant for trait 2: 1 recessive for both traits 1 and 2 C) 1 dominant for both traits: 1 dominant for trait 1 and recessive for trait 2:1 recessive for trait 1 and D) 9 dominant for both traits: 3 dominant for trait 1 and recessive for trait 2:3 recessive for trait 1 and 70. If your calculated chi-square value is 13 and you have 6 degrees of freedom, do you ACCEPT OR REJECT your null hypothesis? A) ACCEPT B) REJECT is used to describe the physical location of a gene on a chromosome, while the genetic 71. The genetic term term, is used to describe two variants (A and A) of the same gene having slightly different sequences. A) alleles; locus B) locus; diploid C) locus; alleles D) diploid; locus E) none of the above are correct 72. Based upon Mendel's monohybrid crosses of pea plants, how did he know that each individual in the Fi generation contained two genetic factors encoding the two different phenotypes? A) The Fi generation had a blended phenotype of the two parental phenotypes 8) Both parental phenotypes reappeared in the F: generation. C) Each F, plant had a different phenotype. D) The F, plants did not have two alleles. E) He was just guessing. 12Explanation / Answer
67. E. Walter Sutton
68. In genetic crosses, F1 stands for First filial generation
71.c. Locus, alleles
