recessive characteristic
the characteristic that does not appear unless recessive alleles cobine eg ff rr small leters
alleles
variation of genes
homologous structures
common ancestor
similar structures

evolution
genetic Chages in characteristics over many generation
natural selection
overproduction variation competition selection

natural selection
process where organisms best adapted to an Enviromint well surive black moth
heterozygous heterozygote
Dominant and recessive allele present eg Hh
homozygous homezygote
both alleles the same HH or hh
