Chapter 09 Patterns of Genetic Inheritance Student: ___________________________________________________________________________ 1. One genetics idea in the early 1800s described that a red-flowered plant crossed with a white-flowered plant would produce offspring which are pink-flowered plants. This concept was called A. Mendel's law B. blending model C. artificial selection D. Darwin's model E. natural selection 2. Which of the following was not a factor in choosing the pea plant to perform genetic experiments? A. It produces many offspring B. The flower is not enclosed in petals C. It has a short generation time D. It is easy to culture E. They can be easily pollinated 3. Which of the following was not a factor in choosing the pea plant to perform genetic experiments? A. It is easy to culture B. It produces many offspring C. The flower is not enclosed in petals D. It has a short generation time E. They can be easily pollinated 4. If a biologist wanted to manually cross-fertilize two pea plants, which of the following steps must be taken? A. Transfer pollen from one plant to the other B. Transfer a pea from one plant to the other C. Transfer the egg from one plant to the other D. Transfer the stigma from one plant to the other E. Transfer the ovule from one plant to the other 5. In a Mendelian monohybrid cross, the _______ generation is always completely heterozygous. A. F3 B. P C. F2 D. P2 E. F1 6. In which kind of cross would you expect to find a ratio of 3:1 among the F2 offspring? A. Monohybrid cross B. Genotypic cross C. Phenotypic cross D. Test cross E. Dihybrid cross 7. Mendel's law of segregation implies that the two members of an allelic pair: A. Are segregated pair wise B. Are distributed to the same gamete C. Are distributed to separate gametes D. Must always code for the identical trait or feature E. Are assorted dependently 8. Which is not true according to Mendel's law of segregation? A. One factor must be dominant and one factor recessive in each individual B. Factors separate from each other during gamete formation C. Each gamete contains one copy of each factor D. Fertilization restores the presence of two factors E. Each individual contains two factors for each trait 9. What are alleles? A. Genes for different traits, such as hair color and eye color B. Dominant forms of a kind of characteristic carried by genes C. Recessive forms of a kind of characteristic carried by genes D. The locations of genes on chromosomes E. Alternative forms of a gene for a single trait, such as blue eyes and brown eyes 10. Which of the following terms is represented by word descriptions, such as brown or tall? A. Phenotype B. Homozygous C. Allele D. Genotype E. Dominance 11. In humans, brown eyes (B) are dominant over blue eyes (b). A brown-eyed woman who has a blue-eyed child would have the genotype: A. Bb B. BBB C. BbBb D. bb E. BB 12. When an organism has two identical alleles for a trait we would refer to this condition as: A. Phenotype B. GenotypeB.... View Full Document
