Question

How do lethal genes cause death in unborn babies and later after birth?​

Answer 1

Answer:

Recessive lethal genes can code for either dominant or recessive traits, but they do not actually cause death unless an organism carries two copies of the lethal allele. Examples of human diseases caused by recessive lethal alleles include cystic fibrosis, sickle-cell anaemia, and achondroplasia.
