The estimated heritability of 48 percent for neuroticism in the population supports the claim that Group of answer choices the population in general has a recessive gene for neuroticism. the incidence of neuroticism is associated with that of another distinct trait. the variability in neuroticism is due partly to genetic variability in the population. those with the neurotic trait share a particular dominant allele.

the variability in neuroticism is due partly to genetic variability in the population.

Explanation:  

In population genetics, heritability (h) is defined as the amount of the phenotypic variation attributable to genetic factors rather than environmental factors.

Mathematically, h is calculated by using the following equation: H2 = Vg/Vp, where Vg is the variation in genotype, while Vp is the variation in phenotype.

An H value close to zero (0) indicates a very low heritability (i.e., the phenotype depends on the environmental differences between individuals), while an H close to one (1) indicates very high heritability (i.e., the phenotype is firstly dependent on genetic factors).

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
