Blending Theory
Opposite of hybrid. Offspring that are the result of breeding genetically similar plants or animals.
Purebred
Unit of inheritance usually occurring at specific loci on chromosome.
Genes
Alternate forms of the same gene. express different traits.
Alleles
Genotype consisting of 2 identical alleles of a gene for particular trait
Homozygous genotype
General term for allele that masks the presents of another allele
Dominant allele
General term for allele that is masked by the presents of another allele
Recessive allele
Mendel's principle of genetic inheritance that states that any particular trait, the genes from each parent separate (during formation of gametes)
Principle of segregation.
genes are passed to offspring independently
Principle of independent assortment
a trait that is determined by the by the combined effect of more than one gene.
Polygenic trait
pink flowers show
Incomplete dominance
Two different traits expressed in the phenotype of heterozygous individuals unblended. AB blood
Codominance
inheritance pattern in which a gene has more than 2 alleles. ABO blood is a example
Multiple allele series
genes that can alter how certain other genes are expressed in a phenotype.
Modifying genes
gene that can either initiate or block the expression of other genes
Regulator Gene
genes that need certain environmental factors to show up. Ex gene for type II diabetes
Incompletely penetrant genes
