[Q]: I know that the answer to the question "Why do some alleles survive and others not?" is in "Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotype traits. Colloquial usage of the term "having a gene" (e.g., "good genes," "hair colour gene") typically refers to having a different allele of the gene. Genes evolve due to natural selection or survival of the fittest of the alleles.". Can you tell me what it is?
****
[A]: natural selection or survival of the fittest


[Q]: I know that the answer to the question "What is an example of a large number of genes?" is in "The genome size, and the number of genes it encodes varies widely between organisms. The smallest genomes occur in viruses (which can have as few as 2 protein-coding genes), and viroids (which act as a single non-coding RNA gene). Conversely, plants can have extremely large genomes, with rice containing >46,000 protein-coding genes. The total number of protein-coding genes (the Earth's proteome) is estimated to be 5 million sequences.". Can you tell me what it is?
****
[A]: rice containing >46,000 protein-coding genes


[Q]: I know that the answer to the question "What was the importance of the generators on the island?" is in "On 13 February 2008, fire destroyed the fishing factory and the four generators that supplied power to the island. On 14 March 2008, new generators were installed and uninterrupted power was restored. This fire was devastating to the island because fishing is a mainstay of the economy. While a new factory was being planned and built, M/V Kelso came to the island and acted as a factory ship, with island fishermen based on board for stints normally of one week. The new facility was ready in July 2009, for the start of the 2009–10 fishing season.". Can you tell me what it is?
****
[A]: supplied power


[Q]: I know that the answer to the question "What has to happen for the pope to announce the appointment?" is in "If conditions change, so that the pope judges it safe to make the appointment public, he may do so at any time. The cardinal in question then ranks in precedence with those raised to the cardinalate at the time of his in pectore appointment. If a pope dies before revealing the identity of an in pectore cardinal, the cardinalate expires.". Can you tell me what it is?
****
[A]:
conditions change
