Genetics
| Question | Answer |
|---|---|
| The transmission of traits from their parents to their offspring is: | Heredity |
| Referring to an allele that masks the presence of another allele for the same characteristic: | Dominant |
| Referring to a pair of alleles that are identical | Homozygous |
| Referring to an allele that is masked by the presence of another allele for the same characteristic: | Recessive |
| The external appearance of an organism that is determined by the individual's genotype is one's | Phenotype |
| The genetic makeup of an organism is its | Genotype |
| Characteristics of the species or individuals of the species such as tallness or shortness,eye color,foot length or tail length can be observed are called: | Traits |
| Referring to a pair of alleles that are not identical | Heterozygous |
| The number of times an event is expected to happen divided by the number of opportunities for an event to happen is | Probability |
| The field of biology devoted to understanding how traits are passed from parents to offspring is | Genetics |
| An alternative form of a gene is an | Allele |
| An inheritance relationship in which one allele is completely dominant over is: | Complete Dominance |
| The dominant trait for hair-length in hampsters is short hair (S). The recessive trait is long hair (s). Which of the following genotypes yields progeny with long hair? | ss |
| Who is the "father of genetics?" | Gregor Mendel |
| Pick the best defintion for "genetics" | Field of Biology that is devoted to understanding how traits are transmitted from parents to offspring. |
| If brown hair (H) is dominant trait and blonde hair (h) is recessive trait, the genotype Hh produces what phenotype? | Brown |
| Briefly describe an allele? | Alternate form of a gene. |
| How many phenotypes are possible from and an incomplete dominance situation? For example, Red flowers are incompletely dominant to white flowers in Jap. 4 o'clocks. What phenotypes would be possible? What genotypes? | three phenotypes... Red, white and pink. Genotypes- RR, Rw, and ww |
| Synonym for homozygous | pure |
| Synonym for heterozygous | hybrid |
| An inheritance relationship in which both alleles are different but contribute equally to the phenotype | Co - dominance |
| An inheritance relationship in which both alleles are different but both have influence in the phenotype | Incomplete Dominance |
| A cross dealing with only one trait | monohybrid |
| A cross dealing with two traits | dihybrid |
| Crossing an unknown genotype with a homozygous recessive genotype to determine the unknown genotype is called ? | a testcross |
| The sugar that appears on RBC's that is a result of the your blood type alleles | antigens |
| Type B blood has what antibodies in its plasma | Type A |
| The universal blood type donor is | 0- |
| The blood type that can receive any other blood type | AB+ |
| What antigens are on type 0 blood | none |
| Define agglutination | clumping together of blood cells preventing flow due to an incompatible combination of blood types |
| Can Rh- people receive Rh + blood | no |
| What kind of trait is blood type | multiple allele |
| What are the alleles for blood type ? | A, B, AB, O |
