WebA person heterozygous for this allele will have shortened limbs and short stature (achondroplasia), a condition that is not lethal. However, homozygosity for the same allele causes death during embryonic development or the first months of life, an example of recessive lethality ^ {7,9} 7,9. WebWhen carrying two copies of an allele is disadvantageous, but carrying only one copy is advantageous, natural selection will not remove the allele from the population — the advantage conferred in its heterozygous state keeps the allele around. For example, the allele that causes sickle cell anemia is deleterious if you carry two copies of it. ...
