1,000
what are genes
set of instructions that determines our traits
two types of genes
dominant
recessive
what do we call our physical traits
phenotype
what do we call our genetic makeup
genotype
whats in the cell
the nucleus
how many pairs of chromosome are in the nucelus
23
one piece of chromosome =
how does it look
gene
coiled
what is the gene made up of
DNA
what is DNA
genetic info
who you are
sepecifc character traits suh as height, features
Allele
variation of a gene
what does the 23rd chromosome say
if youre female or male
sign for female and male
XX
XY
Punnet Square
Heredity and Genes
Monozygontic twins
one egg
one cell
= identical
Dizygonic Twins
two eggs = fraternal
How do we get diseases
especially genetic
but environment plays a role
e/t we do or have
has a genetic component as well as environment
what if we ignore our genetic and environment
STUPID
what is height
hereditery
what is alcohlism
hereditry and environmental
correlation with near sightedness and
high acheivemnet
3 main parts of prenatal development
Germinal Period
Embryonic Period
Fetal Period
Germinal Period
first 2 weeks
Embryonic Period
3-8 weeks (body structure emerges)
Fetal Period
9 - birth
During pregnancy what do we do to check on mom and baby
blood pressure
weight
heart beat monitoring
pee and blood testing
Sonograms
what can sonograms provide
if there is a baby or not
Teratogen
ex:
a/t that increase prenatal abnormalities
stress, malnutrion, drugs
BEHAVIORAL TERATOGENS.
ex:
TERATOGEN’s that affect the fetus’s
brain – causing behavioral issues
such as hyperactive, antisocial, or
learning disabled
TIMING
: is crucial……
THRESHOLD EFFECT…..
long time being exposed
just b/c exposed once, won’t affect
can control ur environment
a change in a stimulus does not produce a noticeable effect until a certain critical point, known as the threshold, is reached.
Low Birth Wieght
Less than 5.5 pound
Very Low Birthweight
less than 3.3 lbs
EXTREMELY Low birthweight
less than 2 lb 3 oz
Preterm
born beforr 37 weeks
small for gestational age
birth weight below the 10th percentile for their gestational age.
when a baby is born what does it need
a lot of NeoNatal Bonding = CRUCIAL
parent infant bonding
touch is crucial to develop bonding
kangaroo care
baby lies on mother, feeling her heartbeat
Post-partum depression
How does mother feel
May be what
mother feels unprepared
unsuccessful for caring for baby
may be physiological or physcologicAL
