Dominant lethal alleles are quickly removed from the pool while the recessive ones remain.

A. True

B. False

The question was asked during a job interview.

Asked question is from Lethal Alleles topic in division Extension and Deviation from Mendelian Genetic Principles of Cytogenetics

Right answer is A. True

Easy explanation: If the lethal allele is dominant it will be expressed even in heterozygotes. This will lead to the death of most individuals carrying the gene and if that is before the mating age the gene will gradually be eradicated from the gene pool.
