Document Summary
Example 1: red flower petal color allele is dominant to the yellow flower color allele. Example 2: red flower petal color allele is dominant to the yellow flower color allele. Example 3: red flower petal color allele is dominant to the yellow flower color allele. Make sure to evaluate the question being asked. Need to be able to identify parents if not stated directly in problem. (be familiar with terms like dominant, recessive, homozygous, heterozygous, and self-crossing) Focus on what allele is dominant, usually code that with a capital letter (letter can be whatever you like, just make sure you know what it is) Know that genotypes are the letters of the alleles and phenotypes are the physical characteristic. Not shown as an example but if you cross two homozygous recessive yellow flowers, you will get all yellow flowers (same with homozygous dominant red flowers)
