Inheritance Flashcards
Phenotype
Physical trait or characteristic whose expression is determined by specific proteins
Homozygous
Individuals with identical copies of an allele
Heterozygous
Individuals with different alleles
Dominant alleles
An allele that determines phenotype regardless of the other allele
Recessive allele
An allele whose effect is masked by dominant alleles
Incomplete Dominance
Each copy of dominant allele provides some expression
Sickle Cell Anemia
Polygenic Inheritance
Traits determined by multiple alleles and several genes
Height
Sex-influenced Genes
Certain genes not on sex chromosomes but still greatly influenced by sex hormones that affect expression
(Male-patterned baldness)
Dogma of Gene Expression
DNA (gene) ➡️ RNA ➡️ Protein ➡️ Phenotype
