Punnet Squares Flashcards
Heredity
The pass of genetic material from parents to offspring
Genes
Are segments of DNA found in chromosomes that give instructions for producing a certain characteristics.
Alleles
That different versions of a gene
Genotype
The combination of alleles that you inherited from your parents.
Phenotype
Your observable traits
Dominant
Allele contributes to the phenotype if one or two copies are present in the genotype
Recessive
Allele contributes to phenotype only when two copies of it are present
Incomplete dominance
Each allele in a heterozygous individual influence the phenotype.
Codominance
Both of the alleles in a heterozygous individual contribute to the phenotype.
Trait
Characteristics passed from one generation to another.
