Part A: If one follows 70 primary oocytes in an animal through their various stages of oogenesis, how many secondary oocytes wou
olga nikolaevna [1]

Answer:

<u>Part A</u> : 70 secondary oocytes will be formed.

<u>Part B</u> : 70 first polar bodies will be formed.

<u>Part C</u> : 70 ootids will be formed.

Explanation:

During oogenesis growth maturation of a single oogonium produces one primary oogonium.

the primary oogonium then undergoes meiosis -1 and produces  one secondary oocyte and first polar body.

The secondary oocyte then undergoes meiosis - 2 and forms an ootid and second polar body.

The ootid then differentiates into the ovum.

As in the above scenario , 70 primary oocytes are present , they undergo meiosis-1 and produces 70 secondary oocytes and 70 first polar bodies. Hence answers of part A and B is 70.

As 70 secondary oocytes are formed , they undergo meiosis -2 and forms 70 ootids which then differentiate in 70 ovums.
