In a woman’s ovary, 20 primary oocytes completed meiosis (assume the first polar body also divided). In humans 2n = 46. 1) Explain the stages of oogenesis and how it differs from spermatogenesis. 2) Find the numbers of eggs and polar bodies formed. 3) Calculate the number of chromosomes in all eggs and the total number of chromosomes in all cells formed. For each part, write out the law or method used (cross scheme, formulas, reasoning) and all calculations step by step.
The AI score is an estimate. In the official exam the written part is marked by BMBA examiners.
