Non Mendelian Genetics

They use RNA not DNA

Having a dominant allele doesn't necessarily mean that trait will show

There are no dominant alleles, only recessive ones in these patterns

They defy the laws of nature.

the dominant allele isn't completely expressed when the recessive one is present.

both alleles are considered dominants, so both traits show up.

more than one gene works together to determine a trait

1 gene depends on another to be expressed.

Heterozygote snapdragons are pink, not red or white

Heterozygote chickens are black AND white, not just one or the other

to show how some genes aren't carried on chromosomes

to show how Mendel was wrong
