Which statement correctly describes the role of allelomorphs in genetics?

1. Gregor Mendel is known as the father of genetics and proposed the laws of inheritance.
2. Allelomorphs are responsible for controlling various expressions or variations of the same trait.
3. The cross IAIB × IAIB results in genotypes such as IAIA, IAIB, IBIB, and IAIO.
4. Crossing it with Tt produces offspring that are 50% recessive and 50% heterozygous dominant.
