Variations found in Mendelian Genetics: Incomplete Dominance Multiple Alleles Co-dominance Sex linkage Epistasis/Pleiotropy Polygenic inheritance Variations in Phenotypes Result in changes in ratios of offspring, but alleles are inherited in the same manner. Incomplete Dominance a situation in which the heterozygote has a different phenotype from the homozygote ; the heterozygous individuals have a phenotype intermediate to the homozygous individuals Red X White Pink Clicker: In snapdragons crossing 2 pink flowers will produce which of the following offspring? Multiple Alleles: Any given gene may exist in more than two forms or alleles Individual (diploid): No more than 2 alleles per gene Population: No more than 2n alleles per gene Co-dominance The heterozygote expresses both alleles (phenotypes) simultaneously. Sex Linkage The result of genes located on one of the sex chromosomes (X or Y), but not the other.
