Single-gene variations — types?
Incomplete dominance, codominance, lethal alleles, multiple alleles.
Multiple alleles concept
More than two alleles possible at one gene locus.
Protein dominance — threshold?
≥50% functional protein causes dominant phenotype.
Incomplete dominance
Intermediate phenotype in heterozygotes.
Codominance example
Both alleles expressed in heterozygotes.
Lethal alleles
Homozygous can cause death, heterozygous viable.
Pedigree purpose
Traces inheritance across generations.
Product rule in genetics
Calculates probability of linked genetic events.
Protein function and dominance
Protein amount influences dominant or recessive phenotype.
