Cards

Term
Autosomes
Definition
The first 22 genes.
Term
Codominance
Definition
When both phenotypes appear. (Cow, Zebra)
Term
Complete Dominance
Definition
When either a phenotype is present or not. (Hairy Knuckles)
Term
Homologous Alleles
Definition
One identical pair of traits from the same chromosomes. (Hair color, Hitch-Hiker's Thumb)
Term
Incomplete Dominance
Definition
A blend between the 2 phenotypes. (Pink Flower)
Term
Multiple Alleles
Definition
A trait controlled by 4 alleles.
Term
Pedigree
Definition
Graphic representation of genetic inheritance.
Term
Phenotype
Definition
Physical Appearance of genes.
Term
Polygenic Inheritance
Definition
Allele is found on 2 or more genes.
Phenotypes show a range of variation.
(Hair color, Eye color, Skin color)
Term
Sex Chromosomes
Definition
The 23rd pair in chromosomes that differs from male and female.
Term
Sex Linked Traits
Definition
Most traits carried on chromosome.
Affects Males more than Females.
Term
External Environmental Factor that affects gene function
Definition
Temperature, Light, Nutrition, Chemicals.
(Color of leaf or fur)
Term
Internal Environmental Factor that affects gene function
Definition
Hormones and Structural differences.
(Baldness or Antlers)
Term
How a Pedigree works
Definition
Circles: Female Squares: Male
Used in conjunction with a punnet square
Individuals can help determine the likely-hood that they carry an allele.
Term
How is incomplete dominance different from multiple alleles?
Definition
Incomplete dominance is a blend between 2 phenotypes (1 allele and chromosome). Multiple alleles is a phenotype controlled by several alleles.
Term
Most human genetic diorders are caused by what?
Definition
Sex-Linked Recessive Heredity
Term
Autosomes
Definition
The first 22 genes.
