A specific characteristic that varies from one individual to another is called a Gene Language Trait Colour 2. Replication of the chromosomes takes place in Interphase Meiosis II Meiosis I Mitosis 3. Which of the following crosses will produce all homozygous offspring? FF x Ff FF x ff Ff x Ff FF x FF 4. Which of the following statements best describes sexual reproduction? Parent cells contribute half of a set of chromosomes each, creating a cell that is genetically different than the parent cell Cells reproduce making identical copies to the parent cell Cells reproduce and pass on the genetic traits of one parent None of the above 5. The genotypic ratio of a cross between one heterozygous dominant and one homozygous dominant individual is 3:1 1:1 1:2:1 None of the above 6. 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 Meiosis None of the above Clamping Removal 7. How many divisions are there in meiosis? 2 4 1 3 8. The allelic make up of an individual is referred to as its Blueprint. Genotype. Phenotype. Genetic pattern. 9. The offspring of crosses between parents with two different traits are called Recessive Hybrids Homozygous Dominant 10. The observable outward manifestation of the genes of an individual is referred to as its Blueprint. Genotype. Phenotype. Genetic map. 11. Which of the punnet squares above shows the results of a cross between two heterozygous individuals? 1 4 3 2 12. When the two haploid gametes contain two different alleles of a given gene, the resulting offspring is called Discrete. . A haploid. Heterozygous. Homozygous 13. Brown eyes are dominant to blue eyes. What would the phenotypes of the offspring be if the cross was Bb x bb? 100% brown 50% brown, 50% blue 25% brown, 75% blue 75% brown, 25% blue 14. Crossing over results in which of the following? Crossing over does not change the outcome in the offspring New combinations of alleles for a given trait The chromosomes of the parent cell mutate to form new chromosomes The daughter cells to be genetically identical to the parent cells 15. Which alleles will only work if there are two copies? Dominant Homozygous Recessive Variant 16. Chromosomes are found in the Nucleus Cytoplasm Cytroplasm Cell membrane 17. All of the following are produced by meiosis except Sperm Zygote Gamete Egg 18. The separation of alleles during gamete formation is called Meiosis Separation of alleles Segregation Mitosis 19. Characteristics we get from parents have been Gifted Inherited Passed on Cloned 20. How many chromosomes are in each body cell? 44 23 46 24 21. Different forms of a gene are called Recessive factors Alleles Dominant factors Hybrids 22. 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 BB 23. Natural selection is known as Survival of the biggest Survival of the fittest Survival of the fattest Survival of the richest 24. Evidence for Darwins theory of evolution comes from Jurassic park Old bones Fossils The bible 25. In a typical Mendel experiment on pea-seed color, if the dominant yellow seed-bearing plant was crossed with the recessive green seed-bearing plant, the F2 generation will show what ratio of each kind? 3 yellow: 1 green Seeds with patches of green and yellow color 1 yellow: 1 green 1 yellow: 3 green 1 out of 25 Time is Up!
