Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there's 1 in 4 or 25% chance for a child to have OO, or blood type O.
B) can be destroyed by variations in temperature or pH
This is because a change in the temperature or pH changes the shape of the active site of the enzyme so the substrate can no longer bind to the active site. The enzyme has become denatured.
Answer: 9:3:3:1.
A cross between two plants that are heterozygous green and heterozygous tall is completed. What is the phenotypic ratio? The phenotypic ratio for the problem above is 9:3:3:1. Note that when crossing two heterozygous (for both alleles) parents this will always be the ratio.
