Yes

Muskan Sharma 4 months, 2 weeks ago

The megaspore mother cell undergoes meiosis to give rise to 4 haploid cells. Three haploid cells degenerate and one survives to become the embryo sac. The embryo sac enlarges in size and the haploid nucleus undergoes mitosis to form 2 haploid nuclei. The two haploid nuclei further undergo mitosis to form 4 haploid nuclei within the embryo sac. In the final round of mitosis 8 haploid nuclei are produced. Hence, the functional megaspore undergoes 3 mitotic divisions to form eight celled mature embryo sac.

Parthi Patel 4 months, 2 weeks ago

No it is not right to blame a female for *** determination of a child because female's have XX chromosome where on the other hand male's has X and Y chromosome.. Here, If XX chromosome are there it is a girl and if XY chromosome are there then it is a boy.. So a female cannot be blamed for the *** of a child.

Fiddusur Rahman 4 months, 3 weeks ago

No female is not responsibility for birth a male or female child because female have only one X hromosome and a male have two chromosome one is X and another one is Y . So when male partner release x chromosome then the child will be female♀️ and when male partner release Y chromosome then the baby will be male♂️ hence females are not responsible to birth a male or female child it's all depends on male partner

Pranjal Thakur 4 months, 3 weeks ago

No , it is not right to blame a female for *** of child . A female has two X chromosome whereas male have both X and Y chromosomes which decide *** of a child . Hence female is not responsible for gender or *** of a child
