The five steps of the scientific method
Step 1: Ask a question or identify a problem. A scientist learns about the universe by observing
Step 2: Background research.
Step 3: Form a hypothesis.
Step 4: Experiment and observe.
Step 5: Draw a conclusion.
2 ) Matter is the stuff that makes up the universe everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Both atoms and molecules are held together by a form of potential energy called chemical energy.
3 ) Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the state of matter. The three fundamental phases of matter are solid, liquid, and gas.

The survival of the cell depends on chromosome integrity.
Answer:
The proportion of the genotypic recombinants among the offspring from this cross is 75%
Explanation:
Separating the alleles from the parents independently, We have AB, Ab, aB, and ab.
These should be crossed using punnet's square, we will therefore get the genotypic of the 16 progenies as: AABB, AABb, AaBB, AABb, AAbb, AaBb, AaBB, AaBb, aaBB, AaBb, Aabb, aaBb, aabb, aaBb, Aaaa and AaBb. From these, only those in bold retained the genotype of their heterozygous parents. Therefore, 12 out of 16 are genetic recombinant, which are the offspring that differs from their parents after a cross. This made the proportion to be 12/16 X 100 = 75%.
