Multiple Choice 2 points What will be the genetic mix between two individuals with the following genotype: AA X Aa? 50% of the offspring will be heterozygous of the trait None of the offspring will display the dominant trait 100% of the offspring will display the recessive trait 75% of the offspring will display the trait

Crossing an individual who is homozygous dominant for a trait with an individual whose genotype is unknown will most likely produce which set of offspring? The options are a. 100% dominant genotype b. 75% dominant phenotype, 25% recessive phenotype c. 100% dominant phenotype d. 50% dominant phenotype, 50% recessive phenotype

#30 If an individual has a dominant phenotype for a trait and produces an offspring with a recessive phenotype, which of the following is true? 1) the offspring must have at least one dominant allele 2) the dominant parent is heterozygous 3) the other parent must have the recessive phenotype 4) we can't determine the genotype of the dominant parent # 31 Which of the following phenotypes shows up more often in human males than in human females? 1) Huntington's Disease 2) Colorblindness 3) type B blood 4) Sickle Cell anemia # 32 A mother has blood type A, and a father has blood type B. Children produced by these two people could have which of the following blood types? 1) all of the choices are correct 2) type A 3) type AB 4) type O # 33 In plants, tall stem is dominant and short stem is recessive. Which of the following would be true about the plants produced from the pollination between two short stemmed plants. 1) The plants in the next generation would have a different genotype than the parent plants 2) 100 % of the plants in the next generation would be short. 3) We can't predict what the plants in the next generation will look like. 4) the plants in the next generation would have a different phenotype than the parent plants.
