got wrong in starter questions

Question 1

define co dominant

Answer 1

2 alleles that equally contribute to the phenotype

both alleles are expressed and neither are recessive

Question 2

what are the 4 types of mutation

Answer 2

base substitution
base inversion
base deletion + base addition (frame shift mutation)

Question 3

3 ways variation is caused in sexually reproducing organisms

Answer 3

crossing over
independent segregation
random fertilisation

Question 4

name 3 ways genetic diversity can be compared within or between species

Answer 4

a/a sequence
observable characteristics (courtship behaviour)
immune response (albumin)
DNA
RNA

Question 5

define mutation

Answer 5

a random change in bases (in terms of gene mutation)

change in chromosomes for example: Down’s syndrome
(in terms of chromosomal mutation)

Question 6

define silent mutation

Answer 6

genetic code is degenerate

more than 1 triplet code for a/a
so there is a mutation but it doesn’t affect phenotype
