If a gene is fixed in a population: Group of answer choices it cannot undergo mutation. it is located near the centromere on the chromosome, reducing its ability to recombine it cannot undergo mutation. only one allele appears for that gene in that population.

The suitable statement will be - only one allele appears for that gene in that population.

Explanation:

Gene Fixation is a topic of population genetics. It means that fixing the change in a gene from a gene pool and that leads to express only one allele for that gene which only remains after the fixation process, in that population. Normally a gene exists of at least two variants or alleles.    An allele fixation means that only one variant or allele will be expressed in all the populations.  

1. The Los Angeles flood of 1938 was one of the largest floods in the history of Los Angeles, Orange, and Riverside Counties in southern California.

2. The flood was caused by two Pacific storms that swept across the Los Angeles Basin in February-March 1938 and generated almost one year's worth of precipitation in just a few days.

3. The Los Angeles, San Gabriel, and Santa Ana Rivers burst their banks, inundating much of the coastal plain, the San Fernando and San Gabriel Valleys, and the Inland Empire.

4. Flood control structures spared parts of Los Angeles County from destruction, while Orange and Riverside Counties experienced more damage.

5. It caused $78 million of damage ($1.42 billion in 2019 dollars),[2] making it one of the costliest natural disasters in Los Angeles' history.[3] In response to the floods, the U.S. Army Corps of Engineers and other agencies began to channelize local streams in concrete, and built many new flood control dams and debris basins
