Answer:
The law of dominance
Explanation:
This cross (aabb x aabb) is an example of a double homozygous recessive cross. When organisms with recessive traits are crossed among themselves, the offspring will all show the recessive traits. Conversely, when one of the parents (or both) has a dominant allele for one of the genes, the offspring will show the dominant trait in a given proportion which normally is larger than the offspring with the recessive traits. These crosses led Mendel to propose the law of dominance.

Answer:
There are many features that make bacteria survive in harsh conditions. Bacteria are found almost everywhere. There are various types of features found in bacteria. They can survive in harsh conditions because of the energy-generating enzymes, protein synthesis mechanism, biodegradative enzymes, and cell membranes. This adaptation helps them to survive in extreme conditions.
