Answer:
The genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2.
Explanation:
In the example given in the question, the color of the petals of snapdragon flowers are given with the An1 allele having full activity and the An2 allele being the null allele. For the F1 offspring, two snapdragon flowers are crossed, one with red petals which is An1An1 and one with ivory petals which is An2An2. All the genotypes for the F1 offspring will result in An1An2.
Then using this F1 offspring, the F2 offspring is found and the genotype of the F2 offspring will be An1An1 / An1An2 / An1An2 / An2An2.
So the genotypes found in the F2 offspring will be An1An1, An1An2 and An2An2. One red petal snapdragon, 1 ivory snapdragon and 2 pink snapdragons.

Answer:
Explanation:
The main fuction of lysosomal enzymes like lipases ,proteases, carbohydrases is to hydrolyse/digest various unwanted material in the cell. And sometimes to digest some nutrient in the cell.
These enzymes are capable of digesting carbohydrates,proteins,lipids and nucleic acids. Lysosomal enzymes are produced by a memberane bound cell organel called lysosome.
WHAT IF LYSOSOMAL ENZYMES ARE ABSENT:
==> If lysosomal enzymes are absent then build up of various unwanted substances increase to a abnormal level, which may increase toxicity in the cell.
==>build up of various dead or unwated cells in the body will increase,since lysosome have the capacity to digest its own cell.
==> absence of lysosome will will cause the cells to starve,since most of the nutrients in the cells are digested by lysosome enzyme.
==> Can cause a high risk of disease,since lysosome digest its own cell if it is infected with some microbial activity.
