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

Answers

Answer 1

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.

Answers

Answer:

tells you if you right or wrong about what you did

Answer:

SORRY IF LATE BUT HERE IS ANSWER:

A hypothesis is a scientific guess into a phenomenon. Results can either support a hypothesis or falsify them.

The findings that result from an experiment are the results on which the claim on a hypothesis is predicated.

When results conflict with the hypothesis statement, such a conjecture can no longer hold true and therefore, it would be modified or completely discarded.

If results support a hypothesis, then the conjecture is accepted and passed on to further scientific procedure.

How did the location of Alexandria affect Hellenistic culture?
Its location on the sea made it a cultural crossroads.
Its location close to Greece made it an influential city.
Its location introduced Asian culture to the rest of Europe.
Its location isolated it from other cultures in the empire.

Answers

Answer:

Its location on the sea made it a cultural crossroads.

Explanation:

The first option is the correct one because Alexander built the city on this place due to a fact that it enabled him to connect different parts of the Empire. It was a crossroad of trade, knowledge and culture and for a long time the center of Mediterranean.

Second option is not correct as during Hellenistic period Greece was not as important as it was during previous eras, especially classical period.

Third option is not correct as Alexandria is located in Africa.

Fourth option is not correct as Egypt is and was a global center and a crossroad.

1. Why do you think we do not know the Freedom Seeker’s name?

2. Why is it important to know that this Freedom Seeker had only recently arrived from Africa?

3. What challenges did the Freedom Seeker likely face during his escape?


text: In late 1752 a young African man escaped from an enslaver’s estate and vanished into the woods. We don’t know his name. We don’t know what happened to him. But what we can piece together about his life reveals an important part of the city’s past. In the 1600s and 1700s, New York’s economy relied on enslaved labor. What can the records about a person escaping slavery teach us about life in this slave city?

Very few original images of enslaved people survive today. Enslaved people themselves were denied the resources to produce and preserve paintings or drawings, while those who could had little interest in portraying captives.

The typical image of American slavery is set on a southern plantation. But slavery was also an integral part of life in the north. For nearly 200 years, enslaved people in New York provided labor to grow crops, move goods, and run households. At the time the Freedom Seeker made his escape in 1752, enslaved people made up at least a quarter of the workforce in the city and perhaps half of those who worked in outlying agricultural areas.
Like millions of others, this Freedom Seeker was carried to America from Africa in the belly of a slave ship. His enslaver’s advertisement reports that the young man had only recently been “imported” at the time of his escape in 1752. This might mean he arrived on the Wolf, a Livingston-funded slave ship that set sail in September of 1749, bound for the “Coast of Africa.” The Wolf pulled back into New York harbor in early May of 1751. This Freedom Seeker from Livingston’s enslavement was possibly among them.

The first clues about enslaved life can be found in the advertisement itself. Advertisements like this provide rare information about individual fugitives. Enslavers gave meticulous descriptions, hoping that “slave catchers” would be able to identify and return Freedom Seeker. Under almost no other circumstances did writers record such detail about enslaved people in New York.

The ad reports that the missing man had only recently arrived from Africa at the time of his escape. Following New York’s suspected slave insurrection of 1741, enslavers hoped that captives fresh from Africa would be more isolated and disconnected—and therefore more docile—than enslaved people who had already been in the Americas for a time.
Philip Livingston suspected the escaped man was hunkered down “in the Woods near Harlem.” While the wilderness of northern Manhattan made a good hideout, the high reward probably encouraged many New Yorkers to search for him. With the water too cold for swimming, the Freedom Seeker’s only options to escape the island would be to steal a boat or slip across a bridge.

What was daily life like for the Freedom Seeker and other enslaved people in New York? Written records are few, but a pivotal archaeological discovery offers some clues about the experience of enslaved people. In 1991, during excavation for new offices, workers uncovered the African Burial Ground, a long-forgotten cemetery now buried many feet beneath the streets of lower Manhattan. Archaeologists unearthed the remains of 419 individuals at the African Burial Ground—a fraction of the 15,000 believed to be buried there.

Though enslaved people in New York faced brutal conditions and harsh treatment, they did all they could to preserve their own humanity. They created loving family relationships, retained elements of traditional African culture, and challenged their captivity. Resistance took many forms, from refusing to work to violent rebellion. Many, like the Freedom Seeker escaping Livingston, resisted by running away.

Answers

Answer:

Erik Erikson, in stage two of his theory of psychosocial development, asserts that parents who are overly restrictive and harsh give their children a sense of powerlessness and incompetence.

Explanation:

For Erikson, the position of very restrictive and severe parents limits children, decreases self-confidence and even self-esteem. These effects are more severe when parents assume this behavior, mainly in the second stage of the theory of psychosocial development, which is the stage where the child is developing his sense of confidence, security and autonomy. Parental restrictive and severe behavior impairs this development and causes children to develop a feeling of helplessness and incompetence in relation to themselves.

Answer: The law of demand is one of the most fundamental concepts in economics. The law of demand states that quantity purchased varies inversely with price. In other words, the higher the price, the lower the quantity demanded. This occurs because of diminishing marginal utility.
