GENETICS Flashcards
Principle of Dominance and Recessiveness
One gene in a pair may mask the other gene preventing it from having an effect.
Principle of Segregation
The two genes for a characteristic segregate, or separate, during the formation of eggs and sperm (meiosis).
Principle of Independent Assortment
Genes for different characteristics are distributed to reproductive cells independently.
Factors for different characteristics are not connected.
One gene in a pair may mask the other gene preventing it from having an effect.
Principle of Dominance and Recessiveness

Principle of Segregation
Genes for different characteristics are distributed to reproductive cells independently.
Principle of Independent Assortment
Dominant
the gene that will mask the recessive (ex. A, B, C)
Recessive
the gene that needs two of itself to be respected (ex. a, b, c)
the gene that will mask the recessive (ex. A, B, C)
Dominant
the gene that needs two of itself to be respected (ex. a, b, c)
Recessive
Heterozygous
when the two genes are alleyls
when the two genes are alleyls
Heterozygous
Homozygous
when the two letters are the same (ex. aa)
when the two letters are the same (ex. aa)
Homozygous
Monohybrid
dealing with one gene
dealing with one gene
monohybrid
dealing with two genes
dihybrid
dihybrid
dealing with two genes

factors that control the traits of a living thing

Opposite genes (ex. Aa)
Mendel did his experiments with no knowledge of
DNA gene’s chromosomes, meiosis, mitosis
probability
the likelyhood of something occuring
the likelyhood of something occuring
probability
test cross
the crossing of an organism to find out if its homozygous or heterozygous
