Genetics and Reproduction How much genetic material is found in a cloned cell as compared to the original cell? a. b. c. d. twice as much the same amount half as much one-fourth as much Where would you look to find a specific gene? a) b) c) d) In a protein At a chromosme In a diploid cell At an allele A species with 16 pairs of homologs has ____ chromosomes in each body cell a) b) c) d) 58 32 16 8 Which of the following is a trait? a) b) c) d) Eye color Heart rate Eating habits A and C A species has 52 chromosomes. How many chromosomes would be in a sperm cell of this species? A) 16 B) 26 C) 32 D) 8 Mike and his three brothers all have brown hair. Mike's father has brown hair, too. Mike's mother, however, is the only family member that has red hair color. What conclusion can you draw about the gene for hair color? a. The gene for red hair is dominant over the gene for brown hair. b. The gene for brown hair is dominant over the gene for red hair. c. Neither brown nor red are dominant since they both occur in the same family. d. Red and brown genes are co-dominant. 18. Single-celled organisms can reproduce and create cells exactly like themselves without combining genes from two different parent cells. When they do this, they use a type of a. asexual reproduction. b. gamete formation. c. natural selection. d. sexual reproduction. 30.Which animal embryo grows inside a shell? a.whale b. rabbit c. mouse d. bird This unicellular organism is reproducing asexually by what method? If a cell lacked ribosomes, it would be unable to A) Manufacture carbohydrates for the cell to use B) Make food through the process of photosynthesis C) Manufacture proteins using genetic material from the nucleus D) Transport materials throughout the cell. 3. When a cell of a plant stem divides, each new cell has a. b. c. d. half the number of chromosomes as the parent cell. the same number of chromosomes as the parent cell. twice the number of chromosomes as the parent cell. four times the number of chromosomes as the parent cell 8. What is true of the offspring of organisms that reproduce sexually? a. b. c. d. They are genetically identical to one of the parents. Genetically, they are completely different from their parents. They have some genetic traits of both parents, but are not exactly like either. They always have twice as many chromosomes as their parents, since they have two parents. Mendel proposed that traits observed in pea plants resulted from a combination of "factors" inherited from each parent. His description of these "factors" can be considered the first scientific definition of the role of — a. ribosomes b. meiosis c. genes d. cell nuclei 21. Brown eyes are dominant to blue eyes. Both of Donna's parents have brown eyes, but Donna has blue eyes. What is the BEST explanation for why Donna has blue eyes? a. b. c. d. All of Donna's grandparents must have had blue eyes. Both of Donna's parents carry a gene for blue eyes. Donna's mother probably carries the gene for blue eyes. Donna's father probably carries the gene for blue eyes.
