Duplication of genes is an important evolutionary mechanism. As a result, many, cases are known in which a species has two or more identical genes.
Suppose there are two genes - A and B - that specify production of the same enzyme. These two genes show autosomal recessive inheritance. An abnormal phenotype results only if an individual does not make any of that enzyme. Only one of these two genes needs to be functional in order to make the enzyme.
What ratio of normal to abnormal progeny would result from a mating between two parents of genotype AaBb where A and B represent alleles that specify production of the enzyme, while a and b do not? Write your ratio like this - e.g 1:2
ratio -
Suppose now there are three genes - A,B and C that specify production of this enzyme and again only one single functional allele is sufficient for a wild-type phenotype. How many of the possible
ratio -
