17
Q

Heterozygous and Homozygous

A

Determine Phenotype

18
Q

Carriers

A

Heterozygous individuals with just one recessive Allele (Dd) can pass that trait on to their children

19
Q

Incomplete dominance

A

A pattern of inheritance in which both alleles are expressed in the phenotype, resulting in a combined trait, or one that is intermediate between the two

20
Q

X-linked inheritance

A

Is when a more harmful allele is carried on the X chromosome. Males are more likely to be affected because their sex chromosome did not match.

21
Q

Genomic Imprinting

A

Alleles are imprinted or chemically marked so that one pair member(either father or mother) is activated, regardless of its make up

22
Q

Mutation

A

A sudden but permanent change in the segment of DNA

23
Q

Polygenic Inheritance

A

In which many genes influence the characteristic

24
Q

Genetic counseling

A

Is a communication process designed to help couples assess their chances of giving birth to a baby with a hereditary disorder and choose the best course of action in view of risks and family goals.

25
Q

Prenatal diagnostic methods

A

Medical procedures that permit detection of development problems before birth

26
Q

Co-parenting

A

Mutually supporting each others parenting behaviors

27
Q

Socioeconomic status

A

Researches asses a families standing on this continuum. Combines three related but not completely overlapping variables 1. years of education and 2 the prestige of ones job and the skill it requires, both of which measure social status and 3. Income which measures economic status.

28
Q

Subcultures

A

Groups of people with beliefs and customs that differ from those of the larger culture

29
Q

Extended family households

A

Where three or more generations live together

30
Q

Collectivist societies

A

Is where people define themselves as part of a group and stress group goals over individual goals.

31
Q

Individualistic societies

A

Where people think of themselves as separate entities and are largely concerned with their own personal needs.

32
Q

Public Policies

A

Laws and government programs designed to improve current conditions

33
Q

Behavioral genetics

A

Is a field devoted to uncovering the contributions of nature and nurture to this diversity in human traits and abilities

34
Q

Heritability Estimates

A

Measure the extent to which individual difference in complex traits in a specific population are due to genetic factors

35
Q

Kinship studies

A

Copare the characteristics of family members

36
Q

Gene-Enviroment interaction

A

People have unique genetically influenced reactions to particular experiences.

37
Q

Gene-Environment correlation

A

Our genes influence the environment to which we are exposed

38
Q

Canalization

A

The tendency of heredity to restrict the development of some characteristic to just one or a few outcomes

39
Q

Niche-Picking

A

Is the Tendency to actively choose environments that complement our heredity

40
Q

Epigenis

A

Means the development resulting from ongoing, bidirectional exchanges between heredity and all levels of the environment
