Which alleles will only work if there are two copies?VariantHomozygousRecessiveDominant2. Different forms of a gene are calledDominant factorsAllelesRecessive factorsHybrids3. A specific characteristic that varies from one individual to another is called a ColourTraitLanguageGene4. When the two haploid gametes contain two different alleles of a given gene, the resulting offspring is calledHomozygousA haploid.Discrete. .Heterozygous.5. A heterozygous round seed plant is crossed with a heterozygous round seed plant. What percentage of the offspring will be homozygous? 25%0%100%50%6. Mendel chose the garden pea for his work on inheritance for all of the following reasons exceptA large number of true breeding varieties were already available.Earlier investigators had shown segregation among the offspring.The generation time was short; many offspring can be grown easily.He could choose to self- or cross-pollinate.7. 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? 1 yellow: 1 green3 yellow: 1 greenSeeds with patches of green and yellow color1 yellow: 3 green8. Down syndrome and sickle cell are caused byMutationsUnited nationsVariationsSolutions9. Which of the following is used to describe a genotype? 100% recessive3:1 ratioBrownAll of the above10. Replication of the chromosomes takes place inInterphaseMeiosis IMitosisMeiosis II11. Mendel referred to the trait that was expressed in the hybrid, F1 or first filial generation as Recessive.Dominant.Codominant.Independent12. A gene for a particular trait that is only expressed in the presence of another gene of the same kind is called a(n) Recessive gene.Codominant gene.Dominant gene.Incompletely dominant gene.13. Which of the punnet squares above shows the results of a cross between two heterozygous individuals?412314. Which of the following statements best describes sexual reproduction? None of the aboveCells reproduce and pass on the genetic traits of one parentParent cells contribute half of a set of chromosomes each, creating a cell that is genetically different than the parent cellCells reproduce making identical copies to the parent cell15. Male sex chromosomes areXYZZYYXX16. Evidence for Darwins theory of evolution comes fromJurassic parkFossilsOld bonesThe bible17. The physical expression of a gene is calledHomozygousPhenotypeHeterozygousGenotype18. Crossing over results in which of the following?The chromosomes of the parent cell mutate to form new chromosomesThe daughter cells to be genetically identical to the parent cellsNew combinations of alleles for a given traitCrossing over does not change the outcome in the offspring19. In pea plants, purple flowers are dominant to white flowers. If two white flowered plants are crossed, what percentage of their offspring will be white flowered? 100%75%0%50%20. If dimples are dominant in humans, what are the possible genotypes of a man with dimples? BB, BbBB, bbNon-dimpledDimples21. The chemical factors that determine traits are called ChromosomesGenesAllelesTraits22. Characteristics we get from parents have beenInheritedPassed onGiftedCloned23. The genetic expression of the trait is called thePhenotypeHomozygous traitGenotypeHeterozygous trait24. Sharon has 100 rabbits. Sevety-nine of her rabbits are black and twenty-oneof the rabbits are white. Based on this information, what can she conclude about the rabbits?The genotypes of the rabbits were Rr x RrThe parents of the rabbits were homozygous dominantThe genotypes of the rabbits were Rr x RROne parent was homozygous dominant and one parent was recessive25.
