Genetics

Father

100

The "daddy" of modern genetics

Gregor Mendel

200

Principle where individuals have two alleles for each characteristics, alleles separate during gamete formation, gametes have one allele for each characteristic, fertilization results in a zygote that has two alleles for each characteristics

Principle of Segregation

300

Principle where each pair of alleles segregates independently of each other pair during gamete formation

Principle of Independent Assignment

400

Information for one characteristics

Genes

500

Different forms of a gene

Alleles

Important stuff

100

genetic makeup

genotype

200

physical characteristics

phenotype

300

Always produce offspring identical to themselves

True breeding

400

cross breeding of two true breeders

Hybrid

500

two different alleles

heterozygous

Important stuff (2)

100

two same alleles

Homozygous

200

always expressed in phenotype if present in the genotype

dominant allele

300

only expressed in phenotype if the genotype is homozygous recessive

recessive allele

400

blood type is this pattern of inheritance

codominance

500

hair color, eye color, color of other stuff is this pattern of inheritance

polygenic inheritance

patterns of inheritance

100

both alleles are fully expressed in phenotype

codominance

200

blending of traits is seen in the phenotype if the genotype is heterozygous

incomplete dominance

300

several genes contribute to one phenotypic characteristics

polygenic inheritance

400

characteristics show up more often in one gender because the gene is on the X chromosome

X - linked inheritance

500

one gene influences several phenotypic characteristics

pleiotropic effects

patterns of inheritance (2)

100

something outside of the organism influences the expression of a gene 

environmental effects

200

one gene controls the expression of another gene

epistasis

300

X - linked inheritance shows up more often in one gender

males

400

Animals that change color throughout the seasons have this pattern of inheritance

environmental effects

500

The color of Labrador retriever puppy dogs showcase this pattern of inheritance

epistasis
