Answer: If it is almost impossible for a favorable trait to get passed down to offspring due to reproductive struggles, the species would not be able to undergo natural selection due to a lack in appearance of a trait.
Explanation:
If there are only two organisms with the adaptation, both of which lack any reproductive abilities, the odds of most of the species <em>not</em> dying out are very low. Only those two will have the adaptation and they rest will die out.

A protein is a polymer of amino acids. When amino acids are joined by dehydration synthesis (a process that removes water to form a chemical bond), they form peptide bonds. There are three main components of an amino acid, the amino group, the side chain, and the carboxylic acid group.
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

is the annual mortality within. a population directly attributable to predation; it represents the level of. successful predator attacks that the animals are unable to control after they. have implemented their antipredator strategies. Predation risk, on the.
<u>random mutations:</u>
What is commonly called "random mutation" does not in fact occur in a mathematically random pattern. The process of genetic mutation is extremely complex, with multiple pathways, involving more than one system. Current research suggests most spontaneous mutations occur as errors in the repair process for damaged DNA.
<u>competition:</u>
the activity or condition of competing.
<u>environmental changes:</u>
Examples of these global environmental changes include climate change, freshwater shortages, loss of biodiversity (with consequent changes to functioning of ecosystems), and exhaustion of fisheries.
