9/5/08 Mendel’s studies: Mendel discovered that all of these genes were diploid Mendel’s Rules: 1. Rule of Segregation a. From an individual diploid they will donate one or the other allele b. Alleles segregate 2. Rule of Independent Assortment a. Alleles segregate independent of each other b. Alleles do not pick and choose which other allele to partner with

Unformatted text preview: Genotype- the genetic construction of an individual Test cross- used to find out the genotype of an unknown dominant. Cross the unknown with a homozygous recessive individual Dominant- this allele suppresses the expression of the recessive allele Recessive- this allele is suppressed by the dominant allele Incomplete dominance- neither trait is completely dominant over the other Codominance- two different alleles that are fully expressed in a heterozygous individual Monohybrid cross- hybrid crossed with another hybrid...
