Verified step by step guidance

Understand the concept of heterozygosity: A heterozygous individual has two different alleles for a particular gene, one inherited from each parent.

Recognize that in many genetic conditions, a recessive allele can cause a disease only if an individual has two copies of that allele (homozygous recessive).

Identify that a heterozygous individual with one normal allele and one recessive allele does not express the disease because the normal allele is dominant.

Learn that such heterozygous individuals can still pass the recessive allele to their offspring, potentially leading to the disease if the offspring inherits another recessive allele from the other parent.

These individuals are known as 'carriers' because they carry the recessive allele without expressing the disease themselves.
