The series of coded nucleotide bases that make up the genetic information in all organisms.
D.N.A. or Deoxyribonucleic acid
The passing down of traits from one generation to the next
Heredity
The study of segments of D.N.A. and how they code for traits in organisms
Genetics
Nitrogen compounds that form the "teeth" or "rungs" of D.N.A.
Nucleotide bases
The amount of chromosomes human offspring typically receive from each parent.
23
Genes that ride on chromosomes in pairs and code for either dominant or recessive traits
Alleles
Tightly wound segments of D.N.A. that are the carriers of genes from parents to offspring
Chromosomes
A pairing of two like alleles
Homozygous
An allele type that if present, will always code for that trait.
Dominant
Any segment of D.N.A. that codes for a trait
Gene
A pairing of two different allele types
Heterozygous
An allele type that requires a homozygous pairing to be present.
Recessive
The four nucleotide bases.
A(Adenine), T(Thymine), C(Cytosine), G(Guanine)
Tool/System used to calculate probability of a certain trait by looking at the potential spread of alleles in an offspring
Punnit squares
The term for an abnormality that get passed down through certain traits
