Evolution , genetics and behaviour

Question 1

Genes definition

Answer 1

units of heredity that maintain structural format through generations - they are part of chroomosomes

Question 2

what are human proteins ?

Answer 2

building blocks of biological systems integral for out behaviour

Question 3

what is an analogy?

Answer 3

similarities in function that evolved independently

Question 4

what is phylogenetic continuity ?

Answer 4

testing for the evolutionary roots of human behaviours - gradual changes within traits

Question 5

Describe the process of how DNA can carry a diversity of information?

Answer 5

• DNA constitutes genes
• DNA codes the synthesis of RNA
• RNA codes the synthesis of protein*

Question 6

genotype definition

Answer 6

Internal genetic code with instructions for making proteins , cells etc

Question 7

What is a phenotype?

Answer 7

The outward manifestation of the genotype i.e physical appearance and behaviour

Question 8

The same genes can have _____ types (alleles)

Answer 8

different

Question 9

genes come in _____ - _______ or ______

Answer 9

1. pairs
2. heterozygous
3. homozygous

Question 10

genes can be _________ or _________

Answer 10

dominant or recessive

Question 11

how many pairs of chromosomes do humans have ?

Answer 11

23 pairs

Question 12

what is a difference between X and Y chromosomes?

Answer 12

Y chromosomes are very small and less likely to carry genetic information than X chromosomes.

Question 13

explain the role of evolution in genetic inheritance

Answer 13

Individuals have different traits within a population this could link to fitness (adaptation) and is evidence by fossils, similarities of related forms , rapid population changes in organisms and geographic distribution.

Question 14

what does evolutionary psychology focus on ?

Answer 14

Functional explanations for behaviour for example - what benefit do our behaviours have and been selected for
