| Question | Answer |
| The outward appearance (gene expression) of a particular trait in an organism is referred to as | a phenotype |
| asexual reproduction | process by which a single parent reproduces by itself |
| binary fission | the division of a prokaryotic cell into two offspring cells |
| budding | asexual reproduction in which a part of the parent organism pinches off and forms a new organism. |
| Some individuals with blood group A may inherit the genes for blond hair, while other individuals with blood group A may inherit the genes for brown hair. This can be explained by the principle of | independent assortment. |
| When a body cell divides through the process of mitosis, the chromosomes in the daughter cells | are identical to the chromosomes of the parent cell. |
| Organisms are able to reproduce either sexually or asexually. Which of the following statements is true of these reproductive processes? | The sorting of genes during sexual reproduction results in a large amount of genetic variation. |
| Most mammals have body cells with a full set of genetic information and gametes with a half set of genetic information. | fertilization; full |
| Asexual reproduction is carried out through __________ division of cells. Therefore, the chromosomes in cells of the new organism are __________ the chromosomes in cells of the parent. | mitotic, identical to |
| ______ is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis. | Crossing over |
| Which of the following cells are produced through meiosis? | sex cells |
| Triple X syndrome, or trisomy X, occurs when a female has an extra X chromosome in each of her cells. This results when the mother's reproductive cells divide improperly, and two X chromosome are moved into one gamete. When that gamete is fertilized and t | nondisjunction |
| During mitosis, one parent cell forms daughter cells that are the parent cell. | two; identical to |
| When environmental conditions change, it is more likely that at least some members of a species will survive if | there is variation among the members. |
| What is the name of the process that appears in the diagram below? | mitosis |
| In squirrels, the gene for gray fur (G) is dominant over the gene for black fur (g). If 50% of a large litter of squirrels are gray, the parental cross that produced this litter was | Gg x gg |
| Which represents the genotype of a homozygous condition? | bb |
| A hybrid black-coated guinea pig produces two million sperm cells. Approximately what number of its sperm cells contain the recessive gene for white coat color? | 1 million |
| Some individuals with blood group A may inherit the genes for blond hair, while other individuals with blood group A may inherit the genes for brown hair. This can be explained by the principle of | independent assortment |
| What percentages can be expected in the offspring of cross between a female carrier for color blindness and a male with normal color vision? | 25% normal male, 25% colorblind males, 25% normal females, 25% carrier females |
| Which cross could produce a child with type O blood? | AO x BO |
| A man with a blood genotype AO marries a woman with a blood genotype of AO. What blood types could be expected in their children? | both type A and type O |
| Sexual 2: | Variation occurs in off springs |
| The outward appearance (gene expression) of a particular trait in an organism is referred to as | a phenotype |
| When many hybrid tall pea plants are cross-pollinated, the offspring produced will probably be | 50% heterozygous tall |
