What organism belongs to more than one trophic level

Alexeev081 [22]

<span>A trophic level pertains to the position of an organism in the food chain. Humans are the mos dominant organism that belong to more than one trophic level. When we eat plants we become the primary consumers but when we eat meat we can become the secondary or the tertiary consumers.

Birds are also organisms that belong to more than one trophic level. When birds eat seeds they become the primary consumer, but when they eat insects they become the secondary or even the tertiary consumers. </span>

Ellis-van Creveld syndrome is a recessive genetic disorder that includes the characteristics of short stature and extra fingers

e-lub [12.9K]

Answer:

D. The frequency of the Ellis-van Creveld allele is 0.0447 in the isolated population and 0.0026 in the general population, which suggests that genetic drift has occurred in the isolated population.

Explanation:

If we assume that one gene is involved in Ellis-van Creveld syndrome and we name that gene with A, then the genotype of the syndrome would be aa.

In population 1, the frequency of the syndrome is 1/150000=0.0000066(it is the frequency of the aa gentotype)

In population 2, the frequency of the syndrome is 1/500=0.002

According to Hardy-Weinberg equilibrium

p2+2pq+q2=1 (p2 is the frequency of the dominant homozygous, 2pq is the frequency of heterozygous and q2 is the frequency of the recessive homozygous).

q or the frequency of the Ellis-van Creveld allele in Population 1 is $\sqrt{0.0000066}$ =0.0026

q or the frequency of the Ellis-van Creveld allele in Population 2 is $\sqrt{0.002}$ = 0.0447
