Biological Bases Flashcards
Genotype
the specific genetic makeup of the individual
phenotype
the individual observable characteristics
Chromosome
is a double stranded and tightly coiled molecule odf deoxyribonudeic acid (DNA)
Alletes
alternative forms of a gene thta produce different characteristics
Dominant
is a gene in the pair receive from both the mother and the father. controls will be displayed
Recessive
Gene received from one parent, the characteristics will not show up unless the partner gene inherited from the other parent is also recessive
DNA
- stands for deoxyriboundeic acid
- DNA transmits instructions for cellular functioning
- DNA IS A DOUCLE STRANDED AND TIGHTLY COILDED molecule
in order for a —- gene to be expressed, it must be inherited from both parents
Recessive
an individual’s observable observable characteristics that can be affected both by other genes and by the environments the —–
Phenotype
Behaviour Genetics
study how genes, environment nd social factors influence psychological and behavioural characteristics. more specifically this attempt to determine the relative influence of genetic and environment factors in accounting for individual differences in behaviour
Family studies
study relatives to determine if genetic similarity is related to similarity in a articular trait
Adoption studies
people who are adopted early in life are compared on some characteristics with both their BIOLOGICAL parents, with whom they share genetic environment, and with adoptive parents with whom they share no genes
the degree of —- demonstrates how genetically similar people are
relatedness
Heritability coefficient
Estimates the extent to which the differences, or variation, in a specific PHENOTYPE CHARACTERISTICS within a group of people can be attribute to variation in their genes.
