The presence of schizophrenia was measured in both monozygotic (MZ) and dizygotic (DZ) twins. The correlation between the MZ twins was .50 and the correlation between the DZ twins was .30. What is the heritability coefficient for schizophrenia?

0.40

Step-by-step explanation:

Given the following :

Correlation between monozygotic twins (MZ) = 0.50

Correlation between dizygotic twins (DZ) = 0.30

Heritability Coefficient is obtained by multiplying by 2, the difference between the monozygotic correlation and dizygotic correlation.

Therefore, Heritability coefficient of schizophrenia :

2 × (monozygotic - dizygotic)

2 × (0.50 - 0.30)

2 × (0.20)

= 0.40

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
