QuestionAnswer
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 gene pair in which the two alleles code for the same trait: 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 gene pair in which two alleles do not code for the same trait: 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

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.
