Answer:
controlled the fertilization process.
Explanation:
Mendel took precautions to avoid contamination by pollen through self pollination of the P generation. He controlled the fertilization processes between the plants. He self pollinated the first pureline varieties to form the P generation. He then cross pollinated them to get F1 generation. Every step of his experiment was controlled.
Some of the conditions that must be met for Hardy-Weinberg equilibrium are:
<span>1. There must be the large population.</span>
2. The population must be isolated, thus there must be no migration.
<span>3. There must be no mutations.</span>
<span>4. There must be random mating.</span>
DNA is a chain of nucleotides bonded together. On that chain there are particular portions of it that the sequence of the nucleotide codes for particular proteins; this is known as a gene. In eukaryotric cells, DNA is coiled around proteins such as histones to form chromatids which when two join at the centre by a centromere to form a chromosome.
