A specific characteristic that varies from one individual to another is called aColourGeneLanguageTrait2. 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: 3 green3 yellow: 1 green1 yellow: 1 greenSeeds with patches of green and yellow color3. Replication of the chromosomes takes place inInterphaseMeiosis IIMitosisMeiosis I4. Evidence for Darwins theory of evolution comes fromOld bonesJurassic parkThe bibleFossils5. When the two haploid gametes contain two different alleles of a given gene, the resulting offspring is calledA haploid.Heterozygous.HomozygousDiscrete. .6. Natural selection is known asSurvival of the fattestSurvival of the fittestSurvival of the biggestSurvival of the richest7. Down syndrome and sickle cell are caused byVariationsSolutionsMutationsUnited nations8. Male sex chromosomes areXXYYZZXY9. 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 green50% heterozygous dominant and 50% recessive100% bb100% homozygous brown10. A diploid organism that has two identical alleles for the same trait is called _______ for that particular traitRecessiveDominantHomozygousHeterozygous11. 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.Dominant gene.Codominant gene.Incompletely dominant gene.12. 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?0%50%75%100%13. A heterozygous round seed plant is crossed with a heterozygous round seed plant. What percentage of the offspring will be homozygous?25%100%50%0%14. A plant breeder wants to create flowers with all red petals. The genotype of the flower that she has is Rr. Which of the following genotypes should she use to make sure that all the petals of the offspring are red.RRrRrrRr15. Characteristics we get from parents have beenGiftedInheritedClonedPassed on16. When an organism has two identical alleles for a trait, the organism is said to beheterezygoushomozygoushomogenousdifferent species17. Mendel referred to the trait that was expressed in the hybrid, F1 or first filial generation asIndependentCodominant.Dominant.Recessive.18. In a heterozygous individual the allele being expressed isRecessive.Masked.Redundant.Dominant.19. Which of the following crosses will produce all homozygous offspring?FF x FFFF x ffFf x FfFF x Ff20. Which of the following statements best describes sexual reproduction?None of the aboveParent 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 cellCells reproduce and pass on the genetic traits of one parent21. Crossing over results in which of the following?The daughter cells to be genetically identical to the parent cellsThe chromosomes of the parent cell mutate to form new chromosomesCrossing over does not change the outcome in the offspringNew combinations of alleles for a given trait22. 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?bbBbBBbB23. The offspring of crosses between parents with two different traits are calledRecessiveHybridsDominantHomozygous24.
