The process by which sperm and egg combine to form an offspring

Study These Flashcards

A

Fertilization

Q

a fertilized egg ( 2 haploids joined together)

Study These Flashcards

A

Zygote

Q

A gene that is expressed only when there are 2 copies of the same alleles (ff)

Study These Flashcards

A

Recessive

Q

2 copies of the same recessive allele (small small letter: gg, FF)

Study These Flashcards

A

Homozygous Recessive

Q

A gene that is expressed either with 1 or 2 copies of the alleles.

Study These Flashcards

A

Dominant

Q

2 copies of the same dominant alleles (big big letter: ie..TT,GG,FF0)

Study These Flashcards

A

Homozygous Dominant

Q

A mixed gene with one dominant allele and one recessive allele; ie.. Tt, Gg, Ff)

Study These Flashcards

A

Heterozygous

Q

Father of genetics. He experimented with pea plants

Study These Flashcards

A

Gregor Mendel

Q

The crossing of gene between two flowers; done by insects, human, winds)

Study These Flashcards

A

Cross Pollination

The crossing of genes between two flowers of same species; human involve in the breeding to select desired traits

Cross Breeding

A pure homozygous dominant or homozygous Recessive

Purebred

a mixture of two gene one dominant and one recessive

Hybrid (mutt)
