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 |

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 |
