Chapter 2 Flashcards
Which of the following is a chromosomally transmitted form of intellectual disability caused by the presence of an extra copy of chromosome 21?
Down syndrome
How are characteristics that suit a species for survival transmitted from one generation to the next?
The genetic code inherited from our parents
______ try to figure out what is responsible for the differences among people: genes, environment, or a combination of both.
Behavior geneticists
______ are units of hereditary information that help cells to reproduce themselves and manufacture the proteins that maintain life.
Genes
______ genotype-environment correlations occur because biological parents, who are genetically related to the child, provide a rearing environment for the child.
Passive
The ______ view states that development is the result of an ongoing, bidirectional interchange between heredity and the environment.
epigenetic
True or false: The emerging view is that complex behaviors are influenced by genes in ways that give people a propensity for a particular developmental trajectory as well as by complex environments.
True
Which of the following is NOT a characteristic of Down syndrome?
An extra Y chromosome
Which of the following would be most commonly used by a behavior geneticist?
Twin or adoption studies
Fertilization typically takes place in the:
fallopian tube.
According to Gilbert Gottlieb’s epigenetic view, which of the following characterizes the relationship between heredity and environment in development?
Bidirectional
According to developmental psychologist David Moore, genetic factors
do not determine phenotypes independently from the contexts in which they develop.
Which of the following takes place during the germinal period of prenatal development?
Creation of the fertilized egg
Attachment of the zygote to the uterine wall
Cell division
Which field seeks to discover the influence of environment and heredity on individual differences in human development?
Behavior genetics
The specialization of cells, also known as cell ______, begins the week after conception.
differentiation
The female egg is known as the:
ovum.
During which period the rate of cell differentiation intensifies, the support systems for cells form, and organs appear?
Embryonic
The _____ period includes the creation of the fertilized egg or zygote, cell division, and attachment of the zygote to the uterine wall.
Germinal
Once the blastocyst attaches to the uterine wall, the mass of cells is known as a(n):
embryo.
The prenatal testing that should be performed depends on which of the following? (Select all that apply)
Genetic risk factors
Medical history
Mother’s age
The fertilized egg is called the:
zygote.
Conception occurs when a single sperm cell from a male unites with an ovum in a process called:
fertilization.
The embryonic period occurs from ____ weeks to eight weeks after conception.
two
Any agent that can potentially cause a birth defect or negatively alter cognitive and behavioral outcomes is referred to as a(n):
teratogen.
