Part 2 Flashcards
Genetic endowment that an individual inherits
Genotype
Observable or measurable characteristics
Phenotype
Sperm penetrates an ovum, forming a zygote
Conception
Single cell formed at conception
Zygote
Stretches of DNA
Genes
Can duplicate itself
DNA
Cell duplicates it’s chromosomes and divides into 2 genetically identical daughter cells
Mitosis
Germ cell divides, producing gametes (sperm/ova) that each contain half of the parent cells
Meiosis
Creating new hereditary combinations
Crossing over
Each pair of chromosomes segregates independently during meiosis
Independent assortment
23rd pair
Sex
Powerful gene that is expressed phenotypically and masks less powerful gene
Dominant Allele
2 heterozygous but equally powerful alleles produce a phenotype in which both genes are fully and equally expressed
Codominance
Also called as Trisomy 21
Down Syndrome
Needle is inserted through the abdominal wall into uterus
Amniocentesis
Environment largely influences where within the range an attribute will fall
Range of reaction principle
Genes or environment may limit the extent the other can influence development
Canalization principle
Study of how genes and environment influence behavior
Behavioral Genetics
Sound waves provide outline of fetus–useful after 14th week
Ultrasound
One of the chromosomes is missing
Turner syndrome
Systematic continuities and changes in the individual that occur between conception and death
Development
Remain the same or continue to reflect our past
Development continuities
Scholar regardless of discipline, who seeks to understand the developmental processes
Developmentalist
Typical patterns of change
Normative Development
Individual variations in patterns of change
Ideographic development
Set of concepts and proposition designed to organize, describe, and explain an existing set of observation
Theory
Explanation for a phenomenon
Hypothesis
Produce consistent and replicable results
Reliability
accurately measure what they are intended to measure
Validity
Technique in which a participants are asked the same question
Structure interview
Interview in which a participants response to each questions determines what the investigator will ask
Clinical method
Observe people as they engage in their everyday activities in the habitats
Naturalistic observation
