Opposite of hybrid. Offspring that are the result of breeding genetically similar plants or animals.
Unit of inheritance usually occurring at specific loci on chromosome.
Alternate forms of the same gene. express different traits.
Genotype consisting of 2 identical alleles of a gene for particular trait
General term for allele that masks the presents of another allele
General term for allele that is masked by the presents of another 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.
pink flowers show
Two different traits expressed in the phenotype of heterozygous individuals unblended. AB blood
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.
gene that can either initiate or block the expression of other genes
genes that need certain environmental factors to show up. Ex gene for type II diabetes
Incompletely penetrant genes
