What are alleles? - (ANSWER)Alternative form of a gene; alleles occur at the same locus on homologous
chromosomes.
What is a phenotype? - (ANSWER)Visible expression of a genotype e.g. brown eyes or attached earlobes.
What is a genotype? - (ANSWER)Genes of an organism for a particular trait or traits; often designated by
letters—for example, BB or Aa.
What is a dominant allele? - (ANSWER)Allele that exerts its phenotypic effect in the
heterozygote; it masks the expression of the
recessive allele.
What is a recessive allele? - (ANSWER)Allele that exerts its phenotypic effect only in
the homozygote; its expression is masked by
a dominant allele.
P - (ANSWER)parental generation
F1 - (ANSWER)first filial generation
F2 - (ANSWER)second filial generation
Law of Segregation - (ANSWER)Each individual has two factors for each trait.
- The factors segregate (separate) during the formation of the gametes.
- Each gamete contains only one factor from each pair of factors.
- Fertilization gives each new individual two factors for each trait.
homozygous - (ANSWER)Possessing two identical alleles for a
particular trait.

Heterozygous - (ANSWER)Possessing unlike alleles for a particular trait.
Punnett Square - (ANSWER)Visual representation developed by Reginald Punnett that is used to
calculate the expected results of simple genetic crosses.
Law of independent assortment - (ANSWER)Each pair of factors separates
independently (without regard to how the others separate).
All possible combinations of factors can occur in the gametes.
incomplete dominance - (ANSWER)Inheritance pattern in which an offspring has an intermediate
phenotype, as when a red-flowered plant and a white-flowered plant produce pink-flowered offspring.
Codominance - (ANSWER)Inheritance pattern in which both alleles of a gene are equally expressed in a
heterozygote.
multiple allele inheritance - (ANSWER)Inheritance pattern in which there are more than two alleles for a
particular trait; each
individual has only two of all possible alleles. blood type
polygenic inheritance - (ANSWER)Pattern of inheritance in which a trait is controlled by several allelic
pairs.
skin color
amino acid - (ANSWER)Organic molecule composed of an amino group and an acid group; covalently
bonds to produce peptide molecules.
protein - (ANSWER)Polymer of amino acids; often consisting of
one or more polypeptides and having a complex three-dimensional shape.
polypeptide - (ANSWER)Polymer of many amino acids linked by peptide bonds.
