Which one of the following statements presents a condition required for the hardy-weinberg principle to be in effect? random matting: individuals pair by chance, not according to their genotypes or phenotypes. no mutations no gene flow no genetic drift

The correct answer is - random mating individuals pair by chance, not according to their genotypes or phenotypes.

Explanation:

Hardy-Weinberg equilibrium explains that if there are no other evolutionary influences on the population then the frequency of genotype in a specific population remains constant over generations.

The assumptions according to this principle are mention as follow -

-No natural selection.  

-no mutation.  

-The population size should be large.  

-There should be random mating  

-No gene flow.

The correct answer is - random mating individuals pair by chance, not according to their genotypes or phenotypes.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

condensation. good luck!
