How are the principles of probability used to predict the outcomes of genetic crosses?

The way in which the alleles segregate is random, and probability allows the calculation of the likelihood that a particular allele combination will occur in offspring

The way in which the alleles segregate is random, and probability allows the calculation of the likelihood that a particular allele combination will occur in offspring

How are Punnett squares used?

Punnett squares can be used to predict and compare the genetic variations that will result from a cross

Describe the terms genotype and phenotype.
