Be creative and make up a new allele that confers a heterozy

Be creative and make up a new allele that confers a heterozygote advantage. State what happens when people are homozygous in both the dominant and recessive states.

Solution

A heterozygote advantage :

Example:

S-ABNORMAL ALLELE

A-------NORMAL ALLELE

GENOTYPE --------SS----------CAUSES DEATH OF AN INDIVIDUAL WITH SICKLE CELL ANAEMAI

=====================================

,

GENOTYPE --------AS--------SICKLE CELL TRAIT –ADVANATGEOUS ---IN MALARIA

ENDEMIC AREAA

======================================================

GENOTYPE --------AA------------NORMAL

========================================================

sickle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.

==========================================================

A)It describes the case in which the heterozygote genotype has a

high relative fitness than either the

B) Heterozygote advantage : it is due to a single locus is known as overdominance.

C) When a single copy of a disease allele doesn\'t result in disease, but instead is favourable for the person or organism that carries it, ------------- heterozygote advantage.
