3.21a Genetic Probabilities

3.21 Predict probabilities of outcomes from monohybrid crosses

• Gamete will contain only one of the 2 alleles
• Then we consider random fertilisation
• Do this by drawing a table to illustrate the possibly fertilisations  that can occur between the pollen grains and the ovules
• In this example it would give us heterozygotes in all squares
• The Genotype of the offspring is big Rr.
