Animal Behaviours Part Ii

Front 1

Heritability

Back 1

The ratio between genetic variance and the total phenotypic variance

Front 2

Heritability formula (H^2)

Back 2

Vg/(Ve + Vg)

Front 3

Range of heritability

Back 3

0-1 or 0-100%

Front 4

Problems with heritability estimates from a scientific perspective

Back 4

1. major racial groups are not genetically well-defined
2. Larger genetic variability within compared to between racial groups
3. Phenotypical recordings are biased
4. environmental effects are not parse out
5. genes do not have a deterministic effect

Front 5

What is more important: genes or environment?

Back 5

Neither, what is important is how they interact

Front 6

What does 100% heritability mean?

Back 6

The environment is not variable in that population

Front 7

Problems with a scientific perspective

Back 7

1. major racial groups are not genetically well-defined
2. larger genetic variability within than between racial groups
3. Phenotypical recording techniques are biased
4. environmental effects are not isolated out
5. Genes do not have a deterministic effect

Front 8

Why do gene not have deterministic effects?

Back 8

Genes and environment work together. differences among these groups/individuals are different in different environments

Front 9

2 ways in which gene function can be altered

Back 9

1. Histonic Modification
2. Methylation

Front 10

Histonic modification

Back 10

modification of the proteins that the DNA is packed around
