What percentage of the offspring will be homozygous? 0% 50% 100% 25%2. In humans, brown eyes (B) are dominant over blue (b). A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one of whom is blue-eyed. What must the genotype of the man be? Bb bB BB bb3. Which of the punnet squares above shows the results of a cross between two heterozygous individuals? 3 4 1 24. Brown eyes are dominant to blue eyes. What would the phenotypes of the offspring be if the cross was Bb x bb? 75% brown, 25% blue 100% brown 50% brown, 50% blue 25% brown, 75% blue5. The genotypic ratio of a cross between one heterozygous dominant and one homozygous dominant individual is 1:1 None of the above 3:1 1:2:16. Characteristics we get from parents have been Gifted Inherited Passed on Cloned7. An allele that is present but unexpressed is Dominant. Recessive. Functional. Redundant.8. Which of the following crosses will produce all homozygous offspring? FF x ff Ff x Ff FF x FF FF x Ff9. The chemical factors that determine traits are called Genes Chromosomes Traits Alleles10. If dimples are dominant in humans, what are the possible genotypes of a man with dimples? Dimples Non-dimpled BB, bb BB, Bb11. Which alleles will only work if there are two copies? Homozygous Recessive Variant Dominant12. A specific characteristic that varies from one individual to another is called a Gene Language Trait Colour13. All of the following are produced by meiosis except Gamete Sperm Egg Zygote14. Male sex chromosomes are ZZ XY XX YY15. In a heterozygous individual the allele being expressed is Dominant. Masked. Redundant. Recessive.16. The process of reduction division in which the number of chromosomes is cut in half through the separation of homologous chromosomes in a diploid cell is called Removal None of the above Meiosis Clamping17. Replication of the chromosomes takes place in Meiosis I Meiosis II Mitosis Interphase18. The offspring of crosses between parents with two different traits are called Hybrids Dominant Recessive Homozygous19. Mendel referred to the trait that was expressed in the hybrid, F1 or first filial generation as Recessive. Dominant. Codominant. Independent20. A gene for a particular trait that is only expressed in the presence of another gene of the same kind is called a(n) Dominant gene. Codominant gene. Incompletely dominant gene. Recessive gene.21. In a certain species of animal, brown eyes (B) are dominant over green eyes (b). Predict the genotypes of the offspring whose parents are heterozygous brown and green. Brown and green 100% bb 100% homozygous brown 50% heterozygous dominant and 50% recessive22. Evidence for Darwins theory of evolution comes from The bible Old bones Fossils Jurassic park23. How many chromosomes are in each body cell? 44 24 23 4624. How many divisions are there in meiosis? 1 2 3 425. Which of the following statements best describes sexual reproduction? Cells reproduce making identical copies to the parent cell None of the above Parent cells contribute half of a set of chromosomes each, creating a cell that is genetically different than the parent cell Cells reproduce and pass on the genetic traits of one parent26 out of 25Time is Up!
