Codominance & multiple alleles

Question 1

what is codominance?

Answer 1

-instead of one allele being dominant and the other recessice, both alleles are equally dominant which means that boh alleles of a gene are expressed in the phenotype

Question 2

what is an example of codominance?

Answer 2

• in snapdragions the allele for red coloured flowers and white coloured flowers are heterozygous so both dominant allelesare presenty the flower produced will be pink
• however if the flowers are homozygous either red or white colour will be produced as both alleles are not present

Question 3

how is codominance shown?

Answer 3

• subscript is used when there is more than one dominant allele
• for example a captial C (for colour) will be ued and R for red colour and W for white colour which would be written as C^w or C^R

Question 4

wha are multiple alleles ?

Answer 4

-a gene may have more than two alleles that is it has multiple alleles

Question 5

what is an example of multiple alleles?

Answer 5

-with the blood groups there are multiple alleles associated iwith the same antigen whicj results in the blood groups ABO which
