Answer 1

during the process of meiosis, genetic information is shuffled and recombined. This means that each child inherits a unique combination of genes from their parents. Therefore, it is possible for the children to inherit the sickle cell trait from the mother, who has sickle cell anemia, but not from the father, who does not carry the gene. This would result in some children having sickle cell anemia while others do not. Meiosis brings about genetic diversity, making it possible for this variation to occur within a family.
