The answer is <span>D) Organisms in the population must express no mating preferences.
Some of the conditions that must be met for a </span><span>population or an allele to be in Hardy-Weinberg equilibrium are:
1. The population must be <u>very la</u><u>rge</u> - so A) could not be the right answer.
2. There must be <u>no migration</u> and population must be isolated - so B) could not be the right answer.
3. There must be <u>no mutations</u> - so C) could not be the right answer.
4. There must be <u>random mating</u>, which means there are <u>no mating preferences</u> - so, D) is the right answer.

Formation of island chains occurs when convergent boundaries interact and is denoted as option A.
<h3>What is Convergent boundary?</h3>

<span>There
are several ways that plants avoid self-shading.
One is through <span>phyllotaxis which is the arrangement
of leaves on a tree which ensures each leaf gets maximum exposure to sunlight.
The other is leaf orientation and leaf area index that maximizes sunlight
capture. The other is their support by the stem that ensures that their growth does
not overlap that underneath it</span></span>
The U.S. central plains region -- nicknamed Tornado Alley -- suffers the highest frequency of tornadoes in the world [source: Tarbuck]. Many of these twisters leave death, injury and destruction in their wake, but one stands in a class by itself.
Sweeping out from southeastern Missouri on March 18, 1925, the Tri-State Tornado careened across the southern tip of Illinois before dissipating in lower Indiana. Remarkably, these three locales lie 219 miles (352 kilometers) apart, and the tornado traveled this distance in just three and a half hours [source: SEMP].
