Specific segment of DNA that codes for protein
One of different forms or versions of gene (ex: blue eyes, brown eyes, hazel eyes)
Gene
Specific character of an individual that results from production of certain proteins (ex: eye color)
specific segment of DNA that codes for proteins
One of different forms or versions of a gene (ex: blue eyes, brown eyes, hazel eyes)
Allele
Specific character of an individual that results from production of certain proteins (ex: eye color)
specific segment of DNA that codes for protein
one of different forms or versions of gene (ex: brown eyes, blue eyes, hazel eyes)
Genotype
Genes or DNA that codes for an organisms trait
EX: BB, Bb, bb
Physical observable traits of an organisms
EX: eye color or nose shape
Phenotype
Genes or DNA that codes for an organisms trait
EX: BB, Bb, bb
Physical observable traits of an organism

Recessive
weaker form of trait; lowercase letter; only expressed if both alleles are recessive
stronger form of trait; capital letter; always expressed
both alleles are the same
EX: AA, ee, FF, mm
one allele is dominant, one is recessive
EX: Hh, Ff, Mm
Dominant
weaker form of trait; lowercase letter; only expressed if both alleles are recessive
stronger form of trait; capital letter; always expressed
both alleles are the same
EX: AA, ee, FF, mm
one allele is dominant, one is recessive
EX: Hh, Ff, Mm
Homozygous
weaker form of trait; lowercase letter; only expressed if both alleles are recessive
stronger form of trait; capital letter; always expressed
both alleles are the same
EX: AA, ee, FF, mm
one allele is dominant, one is recessive
EX: Hh, Ff, Mm
Heterozygous
weaker form of trait; lowercase letter; only expressed if both alleles are recessive
stronger form of trait; capital letter; always expressed
both alleles are the same
EX: AA, ee, FF, mm
one allele is dominant, one is recessive
EX: Hh, Ff, Mm
hh is homozygous recessive
True
False
