Genetic Disorder

An autosomal recessive condition affects 1 newborn in 10,000 in a random mating population without any  disruptive acting force. What is the approximate expected frequency of carriers in this population?

1 in 1000 newborns

1 in 500 newborns

1 in 100 newborns

1 in 50 newborns

Assumptions—If a population is large, randomly mating, and not affected by  mutation, migration, or natural selection.

Prediction 1 —The allelic frequencies of a population do not change

Prediction 2- The genotypic frequencies stabilize after one  generation in the proportions p2, 2pq, and q2.

#Unit 11. Evolution and Behavior

The Hardy-Weinberg law, when the assumptions are met, reproduction alone does not alter allelic or genotypic  frequencies.

Hardy-Weinberg law apply to a single locus (di-allelic/ multiple allele).

#Unit 11. Evolution and Behavior

When a population is in Hardy-Weinberg equilibrium, the genotypic frequencies are determined by the allelic  frequencies.

There are ‘n’ numbers of alleles at a given locus in a diploid population. The proportion of all  homozygotes in the population

A. All alleles are equal abundant

B. All alleles are not in equal abundant

(1) 1/n and <1/n  (3) 1/n2 and <1/n2

(2) 1/n and >1/n  (4) 1/n2 and >1/n2
