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.
Answer:
True
Explanation:
Fixed refers to the delivery of rewards on a consistent schedule. Ratio refers to the number of responses that are required in order to receive reinforcement. For example, a fixed-ratio schedule might be delivery a reward for every fifth response. After the subject responds to the stimulus five times, a reward is delivered.
Personal responsibility and work opportunity reconciliation act was a welfare plan that change the nation welfare system which reduce the length of welfare spells and simultaneously preserving the function of welfare as a safety ground for families experiencing financial problems and it rescinded the eligibility of legal immigrants for food stamp assistance and Supplemental Security Income. Personal responsibility and work opportunity reconciliation act of 1996 grant states greater latitude in administering social welfare programs, and implemented new requirements on welfare recipients, including a five-year lifetime limit on benefits.
