During parthenogenesis as the egg develops without meiosis

Options

A. the offsprings are identical in all inherited respect to the mother
B. the offsprings are differ in all inherited respect to the mother
C. there is no relation between mother and offspring genetically
D. none of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Parthenogenesis**: Parthenogenesis is a form of asexual reproduction where an egg develops into an organism without fertilization. In this process, the egg can develop through different mechanisms, one of which is without meiosis.

2. **Meiosis vs. Mitosis**: In typical sexual reproduction, meiosis occurs, which reduces the chromosome number by half and leads to genetic variation. However, in parthenogenesis without meiosis, the egg undergoes mitotic division instead.

3. **Characteristics of Mitosis**: Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell. Therefore, if the egg develops through mitosis, it remains diploid (having two sets of chromosomes).

4. **Apomyctic Parthenogenesis**: The specific type of parthenogenesis where the egg develops without meiosis is called Apomyctic Parthenogenesis. In this case, the offspring produced are clones of the mother.

5. **Conclusion on Offspring**: Since the offspring are produced through mitotic division and are genetically identical to the mother, they will inherit all genetic traits from the mother without any variation.

6. **Choosing the Correct Option**: Based on the above understanding, the correct answer to the question is that the offspring are identical in all inherited respects to the mother.

**Final Answer**: The offspring are identical in all inherited respects to the mother (Option 1).
