Every month ovum released from
ovary on that time ovum joined with sperm conception occurs.
Ovum:
Girl baby in mother’s womb have an approximately 6-7 crores
egg count when that child was born count reduces half amount, child growing
time again egg count reduces from half amount. The girl reach puberty stage
from that every month pituitary produces follicle stimulating hormone (FSH) for
stimulating 10-30 ovum’s growth. ovum’s
are start to growth in ovary. Finally only one ovum get very fast growth
and released from ovary(ovulation).Another hormone produced by pituitary that
is luteinizing hormone help for ovum release from ovary (ovulation).That
released ovum contain 23 chromosome.22 normal chromosome and only one gender or
sex deciding chromosome, that chromosome called X. so women ovum contain(22+X)
chromosome. Ovum slowly moves through fallopian tube.
Sperm:
Intercourse time crores of sperm enter into the woman body
only some thousands count of sperm entering into the uterus again small count
of sperm only reach the fallopian tube only one sperm can enter into the ovum
that slowly move within the fallopian tube. All these happen within 24 hours of
ovum released then only conception occurs because the ovum has the quality or
capability of conception for 24 hours. Sperm contain 23 chromosome.22 ordinary
chromosome or normal chromosome and one sex or gender deciding chromosome that
is called X or Y. women’s have X chromosome only. Men’s can decide the sex of
baby because he has both boy or girl deciding chromosome X or Y.
Baby boy or Baby girl how it occurs?
Normally we have 46 chromosomes. men’s having 44 ordinary
chromosomes 2 sex deciding chromosome (44+XY).one for deciding baby girl that
is X another for deciding baby boy that is called Y. Women’s have 44 ordinary
chromosome 2 sex deciding chromosome that is called XX so(44+XX).In ovum
chromosome count reduce half amount that is 23 so (22+X)at the same time sperm
chromosome amount also reduced to half amount that is 23 in count so(22+X) or
(22+Y). If sperm contain (22+X) chromosome that sperm joined with ovum then
(22+X) + (22+X) = 44+XX baby
is girl
If sperm contain (22+Y)
chromosomes then it join with ovum then
(22+X) + (22+Y) = 44+XY baby
is boy
Baby receive chromosome from
parents and receive characters and other factors from parents.
