Genotypic Ratios
1:2:1
What is Complete Dominance, Incomplete Dominance, or Codominance Genotypic Ratio?
When two opposite hybrids are crossed, the dominant hybrid is only seen
What is Complete Dominance?
3:1
What is Complete Dominance Phenotypic Ratio?
How to calculate the number of copies of a gene
A single gene that determines a number of distinct/seemingly unrelated traits. Ex: Maori people have a gene that causes sterility and respiratory issues.
What is Pleiotropy?
2:1
Ressive Allele Genotype Ratio
The heterozygote crossbreed has a phenotype intermediate between that of the two homozygotes ( a blend of both traits)
What is Incomplete Dominance?
1:2:1
What is Incomplete Dominance or Codominance Phenotypic Ratio?
The most common alleles in a population (allele greater than 1%)
What is Wild-type Allele?
The heterozygote exhibits both characteristics. Example: White and Black color instead of gray. or AB blood type.
What is Codominance?
2:1
What is Recessive Lethality Ratio?
A rare allele in a population (frequency less than 1%)
Spontaneous alteration in genetic material.
What is Mutations?
A gene with only 1 Wild-type allele
What is Monomorhpic?
What is Allele Frequency?
Genes that have more than one common allele. Example: all 3 blood type alleles are common/polymorphs.
What is Polymorphs (otherwise knows as common variants)
