Studied by 6 people
Natural Selection
an evolutionary process by which those individuals of a species that are best adopted are the ones that survived and leave the most fit offspring
Adaptive Behavior
promotes an organism’s survival in its natural habitat
Evolutionary Psychology
states that adaptation, reproduction, and “survival of the fittest” are important in shaping behavior.
chromosome
a threadlike structure that come in 23 pairs tat contain genetic substance DNA
DNA
complex molecule that contains genetic information; it is helix-shaped molecule
Genes
segment of DNA that helps cell to reproduce and manufacture the proteins that maintain life.
Mitosis
cellular reproduction that happens in body cells that produce two genetically identical cells.
Meiosis
a form of cell division that happens in eggs and sperm called gametes. wherein a single cell divides twice to produce four cells containing half the orginal amount of genetic information
fertilization
a stage in reproduction when an egg and sperm unite to form a single cell
zygote
fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm)
Oogenesis
ovum ripens and release every 28 days
spermatogenesis
producing male gametes in testes
genotype
exact pairing of alleles (ex. BB, Bb, bb)
Phenotype
expression of inherited characteristics (ex. blue eyes and green eyes)
down syndrome
a form of intellectual disability caused by the presence of extra copy of chromosome 21
Klinefelter syndrome
a chromosomal disorder in which males have an extra x chromosome, making them XXY instead of XY. They have undeveloped testes and they usually have enlarged breast.
Fragile X Syndrome
a genetic disorder that result from an abnormality in X chromosome, which becomes constricted and often break
turner syndrome
a chromosomal disorder in which either an X chromosome is missing, making person XO instead of XX.
Reciprocal Translocation
two different chromosome have been exchange
Robertsonian Translocation
an entire chromosome has attached to another at the centromere.
Behaviour Genetics
the field concerned with the influence of heredity and environment in individual differences in human traits and development.
heredity-environment correlations
states that heredity directs the type of environment that children will experience.
epigenetic view
emphasizes that development is the result of an ongoing, bidirectional interchange between hereditary and environment.
gene-environment interaction
involves specific measured interaction between DNA and environment.
