the actual alleles that represent a trait on a chromosome
the physical appearance of a trait
alternate form of gene; two types: dominant and recessive
a trait determined by two or more genes
a cross with sets of alleles with two different traits
a cross with sets of alleles with one trait
when two organisms are bred together by an artificial means
a.k.a. self-fertilization; when an organism can supply its own sperm in order to reproduce
segments of DNA which carry instructions for synthesizing proteins
two traits which both appear as dominant in the off spring, A type of inheritance in which two dominant alleles are expressed at the same time without blending of traits.
neither trait is dominant over the other and both are shown or mixed (ex. Pink snapdragons)
The inherited characteristic that appears in an organism.
The inherited characteristic often masked by the dominant characteristic and not seen in an organism.
A genetic cross in which a test organism showing the dominant trait is crossed with one showing the recessive trait; used to determine whether the test organism is homozygous dominant or heterozygous.
ability of one gene to affect an organism in multiple ways [multiple phenotypes]
the meiotic spindle distributes chromosomes to daughter cells without error, but sometimes a ______________ occurs, in which the members of a pair of homologous chromosomes don't moave apart properly during meiosis I; or sister chromatids fail to separate during meiosis II
allele combination with both parts of genotype identical (example: TT or tt)
allele combination with two different parts of genotype (example: Tt)
the specific site of a particular gene on its chromosome
first filial generation; generation after "P"
second filial generation; the generation that occurs when children cross and have children
otherwise known as incest (P x F1)
