answer the following questions thank you **Lactase Persistence and Pastoralism:**Question:Lactase persistence probably came about to allow pastoralists in the Middle East to digest milk, a trait that came about in tandem with cattle that produced more and better milk.Options:- True- False**Understanding the Sickle-Cell Allele:**Question:Which of the following is not true of the sickle-cell allele?Options:- It became an important genetic factor after slash-and-burn agriculture was introduced.- It became an important genetic factor after fields were cleared that put humans near mosquitoes.- It became an important genetic factor approximately 2000 years ago.- It provides a reproductive advantage to heterozygotes.- Only homozygous normals will survive thanks to this trait.

Lactase persistence is the ability of adults to digest the milk sugar "lactose," that is naturally found in milk and milk products. Lactase persistence is common in some people in European countries and pastoral populations in Africa. It is low in non-pastor list communities.Lactase persistence trait is commonly found in people, who practice dairy farming and cattle herding. It is also related to genetic selection of people with the ability to digest lactose.The statement is true.Reason :Because the lactase persistence trait is found in people who practice cattle herding and farming, the pastoralists in the middle east are lactase persistence. They have the ability to digest lactose (milk sugar) and get nutritional benefits from milk.In relation to cattle domestication, the lactase persistence has evolutionary significance and also increases dairying.The lactase persistence trait has ability to digest lactose, which is an advantage due to increased nutritional benefits of consuming milk.For the detailed explanation, please refer step 3
