Genetics Flashcards
Genotype
The particular combination of alleles present.
Phenotype
The character of observable trait of an organism.
Dominant phenotype
One that is observed in the heterozygote and one homozygote.
Recessive phenotype
Only observed in the homozygous condition.
Codominance
The phenotypes of both homozygotes are expressed equality in the heterozygote.
Monohybrid cross
A cross between two individuals involving a single genetic locus.
Pure-breeding strains
Are homozygous at the locus of interest and produce genetically identical progeny.
Sex-linked inheritance
The inheritance pattern determined by genes located on the sex chromosomes.
Carrier
An organism with an allele for a disease that is masked by a normal dominant phenotype.
Dominant phenotype
The observable characteristic that is evident in the heterozygote.
