Which of the following crosses will produce all homozygous offspring? FF x ff Ff x Ff FF x Ff FF x FF2. The features of an organism are its Characteristics Environments Clothes Species3. The offspring of crosses between parents with two different traits are called Homozygous Dominant Hybrids Recessive4. 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 Bb5. Mendel referred to the trait that was expressed in the hybrid, F1 or first filial generation as Recessive. Codominant. Independent Dominant.6. 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. 50% heterozygous dominant and 50% recessive 100% bb 100% homozygous brown Brown and green7. 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%8. The genotypic ratio of a cross between one heterozygous dominant and one homozygous dominant individual is 1:2:1 1:1 None of the above 3:19. What is the end result of meiosis? Four haploid cells genetically different from their parent cells Four diploid cells genetically identical to their parent cells Two haploid cells genetically different from their parent cells Two diploid cells genetically identical to their parent cells10. 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%11. Mendel's experiments had all of the following characteristics except Hybrid plants with alternative forms of traits were produced. Hybrid plants were self-pollinated for several generations. He always used only two plants for his work. Pea plants were self-pollinated for several generations.12. All of the following are produced by meiosis except Gamete Zygote Egg Sperm13. 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. Incompletely dominant gene. Recessive gene. Codominant gene.14. When the two haploid gametes contain two different alleles of a given gene, the resulting offspring is called Heterozygous. A haploid. Homozygous Discrete. .15. Which of the following is used to describe a genotype? 3:1 ratio Brown 100% recessive All of the above16. The physical expression of a gene is called Homozygous Heterozygous Phenotype Genotype17. A specific characteristic that varies from one individual to another is called a Colour Language Trait Gene18. 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 Clamping Meiosis None of the above Removal19. The separation of alleles during gamete formation is called Meiosis Mitosis Segregation Separation of alleles20. Which alleles will only work if there are two copies? Recessive Variant Dominant Homozygous21. 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? 75% 0% 50% 100%22. Male sex chromosomes are YY XY ZZ XX23. In metaphase, the chromosomes Condense to form chromatin Line up in the middle of the cell Form Move topward the centrioles24. A diploid organism that has two identical alleles for the same trait is called _______ for that particular trait Recessive Homozygous Heterozygous Dominant25. In a heterozygous individual the allele being expressed is Recessive. Redundant. Dominant. Masked.26 out of 25Time is Up!
