A unit of heredity that is transferred from a parent to offspring
Gene
Chromosome pairs one from each parent that are the same
Homologous chromosome
A mature haploid germ cell
Gametes
Chromosome that determines the sex of an organism
Sex chromosome
Any chromosome that is not a sex chromosome
Autosomes
Single set of unpaired chromosomes
Haploid
To complete sets of chromosomes one from each parent
Diploid
Type of cell division
Meiosis
Distinguishing quality or characteristic belonging to a person
Trait
Way to explore the genotype of an organism
Test cross
How the offspring of parents with similar characteristics sometimes have offspring with a different characteristics
Law of segregation
One of two or more alternative forms of a gene
Allele
Two of the same alleles
Homozygous
Genetic constitution of an individual organism
Genotype
Physical characteristics
Phenotype
A gene that masks the effects of the recessive gene
Dominant
A gene that is not tangible
Recessive
Diagram that is used to predict the outcome of an offspring
punnett square
Type of genetic breeding experiments
Mono hybrid cross
Mating experiment between two organisms that are identically hybrid
Dihybrid cross
Random combinations of chromosomes in meiosis
Law of independent assortment
Likelihood of an event to occur
Probability
Homologous chromosomes pair up to exchange different segments of genetic material
Crossing over
DNA sequences that are close together on a chromosome
Genetic linkage
Organism that has inherited a recessive allele
Carrier
A gene located in the sex chromosome
Sex linked genes
Intermediate inheritance where one allele is not completely paired
Incomplete dominance
Both alleles of a gene pair are neither dominant or recessive
Codominance
Controlled by a group of nonallelic genes
Polygenic traits
Diagram showing the lineage of an individual
Pedigree
