Biology 12 Flashcards
Carrier
An individual heterozygous for a specific trait
Fetus
A developing baby
Incomplete dominance
An inheritance pattern where the phenotype of a heterozygote is intermediate between those of two homozygotes; neither allele of the pair is dominant but combine and display a new trait
Codominant allele
Pattern where phenotypes of both homozygote parents are produced in heterozygous offspring so that both alleles are equally expressed
Multiple alleles
Traits controlled by more than two alleles
Autosomes
22 pairs of homogyzous chromosomes
Sex chromosomes
Two chromosomes that determine the sex of an individual
Sex-linked traits
Traits controlled by genes located on sex chromosomes
Polygenic inheritance
The inheritance pattern of a trait that is controlled by two or more genes
Karyotype
The chart of chromosome pairs
Pedigree
A graphic representation of genetic inheritance
