Scientists recently discovered that there is this specific gene called "Pitx1" that is responsible for the less of pelvic spines in animals 15,000 years ago. Among the most common example of the animals affected by this gene is are the freshwater skittlebacks.

protection from predators
Explanation:
The density of a population is important because whether individuals are crowded or spread out affects their lives and their interactions with each other.
If the 2 alleles are the equal, the character is homozygous for that allele. If the alleles are different, the character is heterozygous.
When a populace is in Hardy-Weinberg equilibrium for a gene, it isn't always evolving, and allele frequencies will live the equal throughout generations. There are 5 fundamental Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, limitless populace size, and no selection.
To "fix" an allele method that the allele is gift at a frequency of 1.0, so all people withinside the populace have the equal allele at a locus.

Answer:
True
Explanation:
In central nervous system bundle if axons are called tracts or fasciculi. They are mostly named on the basis of their origin. Endoneurium layer which is very delicate surrounds axon. Impulses are carried toward the s brain through spinal cord ascending tracts while descending tracts carry impulses from higher regions of spinal cord or brain to the lower regions.
