Hemophilia is an inherited bleeding disorder where clotting factors are either absent or present in low amounts. As a result, the blood doesn't clot. It is an X-linked recessive trait that is inherited.

<h3>What is X- linked recessive genetic illness?</h3>

Genetic abnormalities known as -X-linked recessive genetic illnesses are brought on by an atypical gene on the X chromosome. "Carriers" for a disease are females who have the disease gene on one of their X chromosomes. The fact that carrier females have a second copy of the gene to make up for the copy with the disease-causing alteration or mutation usually prevents them from showing symptoms of the ailment.

A male has one X chromosome, thus if he gets an X chromosome that carries a gene that causes a disease, the condition will manifest in him. Male X-linked If the other X chromosome from their mother is healthy, all of their daughters will carry the illness gene.

Seeds- form through ____________ reproduction and contain an embryo that gives rise to a new plant. (Have adaptations that allow
Andrei [34K]

Answer:

Seeds- form through <u><em>sexual </em></u>reproduction and contain an embryo that gives rise to a new plant.

Explanation:

The formation of seeds occur when a ripened ovule is fertilized by pollen. If the pollen and the ovule are from the same plant, then it is termed as self-pollination. If the pollen fertilizes the ovule of another plant then it is known as cross pollination. The seed contains the embryo which has the capability to form and generate into a new plant. Hence, the formation of seeds is a phenomenon which occurs in sexually reproducing plants.
