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).

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
