Male sex chromosomes are XX XY YY ZZ 2. A punnett square is used to determine the Result of meiosis Probable outcome of a cross Actual outcome of a cross Result in segregation 3. Mendel referred to the trait that was expressed in the hybrid, F1 or first filial generation as Dominant. Independent Recessive. Codominant. 4. In metaphase, the chromosomes Form Line up in the middle of the cell Move topward the centrioles Condense to form chromatin 5. 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 green 3 yellow: 1 green Seeds with patches of green and yellow color 1 yellow: 3 green 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 Removal Clamping None of the above 7. A heterozygous round seed plant is crossed with a heterozygous round seed plant. What percentage of the offspring will be homozygous? 50% 25% 100% 0% 8. 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. Recessive gene. Codominant gene. Incompletely dominant gene. 9. A specific characteristic that varies from one individual to another is called a Language Colour Gene Trait 10. All of the following are produced by meiosis except Gamete Egg Zygote Sperm 11. Characteristics we get from parents have been Gifted Passed on Cloned Inherited 12. How many divisions are there in meiosis? 4 3 1 2 13. When an organism has two identical alleles for a trait, the organism is said to be different species homozygous heterezygous homogenous 14. What is the end result of meiosis? Four haploid cells genetically different from their parent cells Two diploid cells genetically identical to their parent cells Four diploid cells genetically identical to their parent cells Two haploid cells genetically different from their parent cells 15. The genotypic ratio of a cross between one heterozygous dominant and one homozygous dominant individual is 1:1 3:1 None of the above 1:2:1 16. In a cross between a heterozygous dominant parent with brown fur and a recessive parent with white fur, how many of the offspring will be homozygous dominant for brown fur? 0% 100% 50% 75% 17. The allelic make up of an individual is referred to as its Blueprint. Phenotype. Genotype. Genetic pattern. 18. The genetic expression of the trait is called the Heterozygous trait Homozygous trait Genotype Phenotype 19. If dimples are dominant in humans, what are the possible genotypes of a man with dimples? BB, Bb Dimples Non-dimpled BB, bb 20. An allele that is present but unexpressed is Functional. Dominant. Redundant. Recessive. 21. In a heterozygous individual the allele being expressed is Redundant. Recessive. Dominant. Masked. 22. Different forms of a gene are called Alleles Dominant factors Hybrids Recessive factors 23. 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. rR rr RR Rr 24. The chemical factors that determine traits are called Genes Traits Alleles Chromosomes 25. Chromosomes are found in the Cytroplasm Cell membrane Nucleus Cytoplasm 1 out of 25 Time is Up! Time's up
