Inheritance
... Step 4: Gamete genotypes are S and s for both parents. Step 5: Enter possible fertilizations into the Punnett grid. Note this time each parent will produce two types of gamete. The chance of producing one or other type of gamete is p= 0.5 (50%) or 1 in 2. Step 6. Write out the gamete genotype and ra ...
