Lecture 16 - how are we all different

Question 1

what is the law of segregation

Answer 1

when gametes form, alleles are seperated so that each gamete carries only one allele for each gene

Question 2

what is the law of independence assortment

Answer 2

the segregation of alleles for one gene occurs independently to that of any other gene

Question 3

what is the law of dominance

Answer 3

some alleles are dominant whiles others are recessive; an organism with at least one dominant allele will display the effect if the dominant allele

Question 4

what is an allele

Answer 4

alternative form of a gene that is located in the same place on a chromosome

Question 5

what is a recessive allele

Answer 5

version of a gene that does not encode a functional protein

Question 6

what is the exception to the law of independent assortement

Answer 6

genetic linkage = when two genes are close together on a chromosome that are often inherited together

Question 7

what occurs if the recessive allele is present in both copies

Answer 7

the protein will not be able to form and the pathway will be interfered

Question 8

when the pathway is interfered what can happen

Answer 8

you can get accumulations of somethings and can be lacking in other things - depending on what gene can not be expressed
