Genetica diferențelor individuale

Question 1

what does behavioural genetics study

Answer 1

studies how genes and environments work together to produce variance in traits

Question 2

quantitative genetics: twin studies

Answer 2

how similar are identical twins: 100%

how similar are fraternal twins: 50%

Question 3

what are the aims of quantitative genetics

Answer 3

to understand and quantify the relative contributions of genetic and environmental factors to the variation observed in complex traits.

estimating heritability, identifying genetic variants associated with traits, predicting phenotypic outcomes, and understanding gene-environment interactions.

Question 4

What methods are used to achieve the aims of quantitative genetics

Answer 4

methods used in Quantitative Genetics include twin studies, family studies

Twin studies compare trait similarity between monozygotic and dizygotic twins to estimate heritability.

Family studies examine trait resemblance among relatives with different genetic relatedness.

Question 5

how does environment affect genetic expression

Answer 5

mother’s diet or stress affects developing baby’s gene expressions
