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
The two genes for a characteristic segregate, or separate, during the formation of eggs and sperm (meiosis).
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
