The present models presented in Figure 3 served given that foundation for developing hypothesis that is new.

Spermatogenesis ( Figure 3A ): Spermatocytes bring about 4 spermatids, 2 of which may have X intercourse chromosome while the other 2 spermatids have actually Y sex chromosome. Just 2 associated with the 4 spermatids take part in genetic recombination during meiosis we.

Oogenesis ( Figure 3B ): while the 4 gametes aren’t differentiated, the assumption is that any 2 gametes can develop the additional oocyte ensuing in an ovum with only 1 X chromosome.

Fertilization ( Figure 3C ): During fertilization, some of the 4 haploid spermatozoa can penetrate the ovum and fuse aided by the X intercourse chromosome to make the zygote. The intercourse regarding the offspring is determined according to perhaps the spermatozoon utilizing the X or Y chromosome unites with all the X sex chromosome into the ovum to make the zygote; leading to feminine (XX) or(XY that is male offspring. 4,6

The mobile biology different types of spermatogenesis, oogenesis, and fertilization had been simulated after differentiating intercourse chromosomes as ancestral and parental within the model that is new Figure 4 ). These were methodically analyzed theoretically, plus the findings had been presented the following.

New Types Of Spermatogenesis, Oogenesis, and Fertilization

Spermatogenesis

The various stages of spermatogenesis in meiosis I and II, including recombination, leads to the production of 4 haplo Figure 4A. Just the 2 spermatids which have taken component in hereditary recombination during meiosis I, that is, the‘X’ that is ancestral and parental Y chromosome, are designed for involved in the fertilization procedure. One other 2 spermatids, the ‘X’ and Y which have perhaps perhaps not taken component in recombination, should be inactive and cannot be a part of the fertilization procedure.
