|
|
dominant-recessive inheritance
|
If one of two parents is affected by a genetic condition with a dominant inheritance pattern, every child has a one-in-two chance of being affected. So on average half their children will be affected and half their children will not be affected and so will not pass on the condition. However, as chance determines inheritance, it is also possible that all or none of their children will be affected. Examples of genetic conditions that show a dominant pattern of inheritance are Huntington's disease, achondroplasia and neurofibromatosis.
|
|
recessive inheritance
|
An autosomal recessive disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop.
|
|
polygenic inheritance
|
Many genes determine a characteristic
|
|
gene therapy
|
method of treating genetic disorders that involves replacing the affected genes with genes that do not have the disorder
|
|
mutations
|
single gene mutations can have a dramatic effect, such as the lack of production of a certain protein (resulting in PKU)
|
|
sex-linked inheritance
|
pattern of inheritance in which a recessive characteristic is expressed because it is carried on the male’s X chromosome. the phenotypic expression of an allele related to the chromosomal sex of the individual. This mode of inheritance is in contrast to the inheritance of traits on autosomal chromosomes, where both sexes have the same probability of inheritance. Since humans have many more genes on the X than the Y, there are many more X-linked traits than Y-linked traits.
|
|
PKU
|
Single gene mutation- Infants born with two recessive alleles lack an enzyme that converts phenylalanine into tyrosine
Phynylalanine disrupts neural signaling by inhibiting the formation of myelin |
|

|
|
heritability
|
statistical estimate of the extent to which genes are responsible for the differences among persons within a specific population, with values ranging from 0 to 1.00
-Heritability estimates are population statistics – they tell us NOTHING about individuals -Heritability estimates apply only to the population studied, at that time, under those environmental conditions -High heritability does not mean that environmental interventions would be ineffective |
|
passive genotype
|
theory of genotype-environment effects, the type that results from the fact that in a biological family,parents provide both genes and environment to their children
*It is very difficult to separate genetic influences from environmental influences because parents provide both, and they are likely to provide an environment that reinforces the tendencies they have provided to their children through their genes. |

the endoderm that will become the spinal cord and brain |
|
Maternal stress
|
Causes an elevation of stress hormones in the fetus, an increased likelihood of intrauterine infection and increases chances for preterm labor. In extreme cases, the fetus builds itself permanently to deal with this kind of high-stress environment, and once it's born may be at greater risk for a wide range of stress-related pathologies
|
|
poor maternal nutrition
|
Prenatal nutrition influences risks for serious prenatal problems as well as the risk of premature delivery and low birth weight. Can cause problems much later on down the road (links to disease and sickness, schizophrenia)
-Deficiency in folic acid can cause anencephaly and spinal bifida |
|
maternal attitudes
|
Mothers who resent being pregnant and feel no attachment to their babies are more likely to have children who had emotional problems.
Extreme maternal distress even poses a risk of hurting baby physically, as it has been linked with increased risk of prematurity and low birth weight. |
|
exercise
|
Walking, jogging, or swimming, stimulates the circulatory and muscular systems of a woman’s body. It increases her ability to process oxygen, a benefit for both her and the fetus, and increases muscle tone and strength (preventing back ache and constipation). However high-risk sports should be avoided during
pregnancy. |
|

|
Babies born to mothers who are heavy drinkers in first trimester have 30% chance of Fetal Alcohol Syndrome
-small head -brain abnormalities (lack of convolutions) -eye abnormalities -congenital heart disease -abnormalities of face and joints Heavy drinking = 5+ units of alcohol/day The effects of moderate drinking are less clear. |
|

By the end of the embryonic period, the embryo can respond to touch and can move
|
|
fetal period- major changes

From weeks 9 to 38. Genitals form and release sex hormones; fingernails, toenails, and taste buds develop; organs begin to become functional and there is a tremendous amount of growth in size. Brain development. Vernix and Lanugo are formed. 3 months, 3 ounces, 3 inches
|
|
How a genetically male fetus becomes male
|
A gene in the sex-determining region of the short arm of the Y, now referred to as SRY, has been found to direct production of a protein which binds to DNA, inducing differentiation of cells derived from the genital ridges into testes.In a male, SRY and other genes induce differentiation of supporting cells into Sertoli cells and (indirectly) steroidogenic cells into Leydig cells to form testes, which become microscopically identifiable and begin to produce hormones by week 8. Germ cells become spermatogonia.
|
|
How a genetically female fetus becomes female
|
Without SRY, ovaries form during months 2-6. Failure of ovarian development in 45,X girls (Turner syndrome) implies that two functional copies of several Xp and Xq genes are needed. Germ cells become ovarian follicles. Supporting and steroidogenic cells become theca cells and granulosa cells, respectively.

|
the two ways neurons communicate
|
Neurons differ from other cells in the body in that they are not di-
rectly connected to each other. Instead, they are separated by tiny gaps called synapses. Neurons communicate across the synapses by releasing chemicals called neurotransmitters. The axon of the neuron releases neurotransmitters, and the dendrites receive them. |

Bowlby's stages of attachment
|
Attachment to their mother as an internal working model. Develops in four phases:
Preattachment phase Attachment in the making phase Clear-cut attachment phase Reciprocal attachment phase During the clear-cut attachment phase infants display full-blown separation anxiety. Infants utilize their mother as a secure base. Believed that attachment forms in all but extreme deprivation cases, then: detachment. |

|
|
What is the rouge test and what does it test for?
|
From the age of 18 months, the child simply sees a "sociable playmate" in the mirror's reflection. Self-admiring and embarrassment begin at 12 months, and at 14 to 20 months most children demonstrate avoidance behaviors.[1] Finally, at 18 months half of children recognize the reflection in the mirror as their own and by 28 to 40 months self-recognition climbs to 100%. Children do so by evincing mark-directed behavior; they touch their own nose and/or try to wipe the mark off. The study also found two strong predictors of self-recognition: object stimulation (maternal effort of attracting the attention of the infant to an object either person touched) and mutual eye contact. A strong correlation between self-concept and object permanence have also been demonstrated using the rouge test
|
|
What are secondary emotions, and when are they evident?
|
Emotions that require social learning, such as embarrassment, shame, and
guilt. Secondary emotions are also called sociomoral emotions, because infants are not born knowing what is embarrassing or shameful but have to learn this from their social environment. Secondary emotions develop mostly in the second year of life. |
