Pregnant 
Homeless 
Inmates 
Low income 

Right to privacy-

Q

Biological beginnings- genetic

A

Genotype- genetic makeup of an individual
Phenotype- observable characteristics of an individual

Genetic foundations

  • chromosomes
  • genes
  • DNA

terminology

  • autosomes
  • sex chromosomes (determines gender)
  • gametes (sex cells, sperm, egg (ova))
  • zygote
        Mom.      Dad  Fem.    X.            X Male    X.            Y

All females have two X’s -> protective X
Think this is why females live longer

Twins
Fraternal/dizygotic
Identical/monozygotic
if the split doesn’t fully happen, you have conjoined twins

As age of mother increases- Higher number of multiples-more risk in birth

Alleles
-two forms of the same gene

Average relatedness (biological) 
Share genes->
50% w/ parents 
50% w/ siblings 
25% w/ uncle, aunt, grandparents 
12.5% w/ cousins 

Dominant-recessive inheritance
Coca Cola- not for ppl with PKU
Punant square

Huntingtons disease is related to dominant genes
X-linked inheritance
This X chromosome has one abnormal recessive allele

Q

Dominant vs recessive characteristics

A

Incomplete dominance and polygenic inheritance
-incomplete dominance
(Both alleles of a single gene are expressed)
(Results in combined trait of intermediate between the two)
-polygenic inheritance
(Many genes combine to influence trait

19
Q

Genetic imprinting and mutation

A
Imprinting 
-chemical marker that activates either mother's or father's gene 
-often temporary 
Mutation 
-sudden permanent change in DNA segment 

Blue people of Kentucky
Chromosomal abnormalities

20
Q

Down syndrome

A

-problems w/ the 21st chromosome
-linked to maternal age
1 in 1900 births - age 20
1 in 300 births - age 35
1 in 30 births - age 45

21
Q

Chromosomal abnormalities

A
-sex chromosome abnormalities 
Problems with the X or Y chromosomes 
-klinefelter syndrome (XXY) 
-fragile X 
-turner syndrome (XO) have 45 chromosomes (usually have 46) (occurs only in women) (YO wouldn't survive) 
-XXY syndrome (sperm had two Ys 
(Above average height)
22
Q

Reproductive technologies

A
  • donor insemination
  • invitro fertilization
  • surrogate mother

(Two sperm fertilize one egg)
(California cryobank- sperm bank)

23
Q

Reproductive choices

A
  • Genetic counseling and testing
  • Prenatal diagnosis and fetal medicine
  • Adoption
24
Q

Genetic counseling and testing

A
-90% of pregnancies in US= healthy baby 
Helps couples: 
-assess chances of heredity disorders 
-choose best course of action 
-risks 
-family goals 
Recommended when: 
-couple has had difficulties 
-aware of genetic problems 
-woman is over 35 

Most pregnancies result in a healthy baby

25
Q

Prenatal diagnostic methods

A
  • Amniocentesis
  • chronic villus sambling (CVS)
  • fetoscopy
  • ultrasound
  • maternal blood analysis
  • preimplantation genetic diagnosis

Amniocentesis and CVS
-needle in in belly during ultrasound

Steps to take before conception
50% of pregnancies are unplanned

26
Q

Physical exam

A
  • consider genetic makeup
  • reduce or eliminate toxins
  • proper nutrition (take folic acid)
  • consult doctor after 12 months (after 6 months if over 30- in text book)

35 is late to begin trying

27
Q

Neural tube defects

A

(take folic acid)

  • Failure of neural tube to close
  • Around 28th day after fertilization
  • NC has one of the highest rates in nation
  • Higher in moms who are poor, obese, of English, Irish, or Hispanic heritage, or have diabetes or epilepsy

-reduce risk by 75% by taking 400mg of folic acid daily before conception

28
Q

Environmental contexts for development

A
  • Family
  • Socioeconomic status and family functioning
  • Affluence
  • Poverty
29
Q

Education
Occupation
Income

SES and family functioning

  • timing and duration of family lifecycle
  • father’s involvement
  • values and expectations

  • why might girls not attend school

- why is education important to girls

32
Q

Who is poor

A

51% of American children pre-k to 12th grade are eligible for free or reduced lunch

Poverty in late adulthood

Pension- goes to the person who worked

33

  • individualist
  • collectivist

What type of society does the US have?
Individualist

34
Q

Range of reaction

A

Gene-environment interaction- which means that because of their genetic makeup, individuals differ in their responsiveness to qualities of the environment. In other words, people have unique, genetically influenced reactions to particular experiences.

35
Q

Genetic- environment correlation

A

Our genes influence the environments to which we are exposed

36
Q

The epigenetic framework

A

Development takes place through ongoing, bidirectional exchanges between heredity and all levels of the environment. Genes affect behavior/ experiences. Experiences/ behavior affect gene expression

37
Q

Prenatal development

A

Conception and implantation

  • girls are born with all their eggs
  • by the time you have your first period, you release your first egg
  • release an egg (2 weeks later– get your period)

Vagina-cervix-uterus-fallopian tube

Men-300 million sperm per day

Zygote-blastocyst-implantation

In Fallopian tube- ectopic pregnancy

38

A
2 weeks 
Zygote 
-2 weeks long 
-fertilization 
-implantation 
-start of placenta 
6 weeks 
Embryo 
-6 weeks long 
-arms, legs, face, organs, muscles all develop 
-heart begins beating 

30 weeks

38 weeks total

People said it is 40 weeks- last menstrual period- that’s the date people usually count from (first day of the period)

39
Q

A

You will have a belly button no matter what- that’s where you get all of your nutrients

Consuming the placenta
Could have hepatitis, HIV, etc.

Dose
Heredity

Most commonly occurs when women get it while pregnant

43
Q

Maternal factors in healthy prenatal development

A
  • infectious diseases
