Father
The "daddy" of modern genetics
Gregor Mendel
genetic makeup
two same alleles
Homozygous
both alleles are fully expressed in phenotype
codominance
environmental effects
Principle of Segregation
physical characteristics
phenotype
always expressed in phenotype if present in the genotype
dominant allele
blending of traits is seen in the phenotype if the genotype is heterozygous
incomplete dominance
one gene controls the expression of another gene
epistasis
Principle where each pair of alleles segregates independently of each other pair during gamete formation
Principle of Independent Assignment
True breeding
only expressed in phenotype if the genotype is homozygous recessive
recessive allele
several genes contribute to one phenotypic characteristics
polygenic inheritance
males
Information for one characteristics
Genes
cross breeding of two true breeders
blood type is this pattern of inheritance
codominance
characteristics show up more often in one gender because the gene is on the X chromosome
X - linked inheritance
Animals that change color throughout the seasons have this pattern of inheritance
environmental effects
Different forms of a gene
Alleles
two different alleles
heterozygous
hair color, eye color, color of other stuff is this pattern of inheritance
polygenic inheritance
one gene influences several phenotypic characteristics
pleiotropic effects
The color of Labrador retriever puppy dogs showcase this pattern of inheritance
epistasis
