What kind of heritability estimates (broad sense or narrow sense) are obtained from human twin studies?

Social Studies

kow [346]3 years ago

Answer:

Broad sense Heritability.

Explanation:

Heritability is the proportion of variance, in a particular population, that is due to genetic factors and not to environmental influences or stochastic variation.

We have,

Narrow sense heritability’ (h2)which is the proportion of trait variance that is due to additive genetic effects while

‘broad sense heritability’ (H2) is the proportion of trait variance that is due to all genetic factors including dominance and gene-gene interactions.

For twin studies, the total variance can be split up into genetic, shared or common environmental, and unique environmental components this enables an accurate estimation of heritability"

Broad sense heritability is mostly measured for twin due to their genetic components and additivity gene action, environment and most likely cause of difference in case of dissimilarity among Identical twin.

Fraternal or dizygotic twins on average share half their genes (and so identical while monozygotic (MZ) twins on average are twice as genetically similar as DZ twins.

Determine whether each of the following arguments is a deductive argument or an inductive argument. If the argument is a deducti
kykrilka [37]

Answer:

1. In<u>ductive argument</u>.

2. <u>Inductive argument.</u>

3. <u>Deductve argument.</u>

Explanation:

1. This argument is inductive. The conclusion is a generalization, that is drawn by a premise, the premise has been obtained out of experimentation.

If two grains of sand have diamons, it doesn´t mean the entire beach is made of them. This argument is not strong because the conclusion is not accurate.

2. This is a deductive argument. This type of argument depends on the logic struture of it. If the premise were to be true, the conclusion would be true also.

It is not a sound argument, because thanksgiving happends every fourth thursday of november. It is an invalid argument because the premise is false, there for the concusion is false.

3. This is an invalid deductive argument. The premise is incorrect, so the conclusion that is being deduce from it is also wrong. It is not a sound argument because if you double the length of the sides of a square, the area would quatriple.

Why is active political participation an important responsibility for people in the United States
iVinArrow [24]

Answer:

Active political participation is important for US citizens because of how the US Government gets it's power by the people of the country, as is how most democracies work. Therefore, without that input, the government could not make laws or anything of the sort.

Explanation:

If you have a democracy and people, the people must make the decisions for the democracy because aforementioned twice democracy cannot make it's own decisions, according to the US Constitution. This would leave the government unable to do anything, the country would supposedly fall into a revolt and collapse.

What is the probability that the small bowl of cereal contains more cereal than the large?
Sav [38]

Answer:0.0228

Explanation:

Assuming the letter of Alphabet A is a random variable which represents the small bowl and the letter of Alphabet B is the random variable which represents the large bowl.......

Therefore, the total amount of large bowl and small bowl is B+A and the difference between the large bowl and the small bowl is B-A....................

The first thing to do is to find the variance followed by the determination of the z-score.

(A). Variance= σ= √( σ^2(B) + σ^2(A)..........-----------------------------------------------------------------------------------(1)..

Then,

σ= √(0.4^2 + 0.3^2).

σ= 0.5.

(B). Hence, we calculate for the z-factor.

Therefore, z= 0 - 1/ 0.5.

= -2.

So, P(B - A < 0) = 0.0228.
