Answer:

<u>Answer to Question 1:</u>

Sickle cell anemia is a recessive disorder. The fact that one of their children is a carrier means that either of Keith and Marsha is a carrier ot it might be that both of them are carriers of the disease.

<u>Answer to Question 2:</u>

The other two kids of Jeff and Adrienne who don't have the genetic disease are still carriers of sickle cell anemia.

<u>Answer to Question 3:</u>

Adrienne is a carrier of the sickle cell anemia disease as well, just like Jeff.

Hope that answers the question, have a great day!

During Prophase chromosomes condense, and mitotic spindle form, chromosomes are copied, and the nuclear membrane disappears, spindle fibres pull the sister chromatids apart.

Explanation:

Prophase is divided into 2 sub-phases as early Prophase and late prophase.

Early Prophase:

In early prophase distinct thick chromosome like structures, Centrioles move to the opposite poles and, nuclear membrane disappears

By late prophase:

Astral rays and spindle fibres are formed. Spindle fibres attach to the chromosome. Contractions occur in the attachment and sister chromatids are pull apart towards the equator.

Metaphase will follow the prophase.
