How does gender affect the development of a child?
In many communities, gender inequality is one important root cause of children’s poor development in the early years. Gender discrimination together with son preference mean that young girls receive less nutrition, opportunities to play and access early learning than young boys.
Can a girl be born with XY chromosomes?
“Girls born with XY chromosomes are genetically boys but for a variety of reasons – mutations in genes that determine sexual development – the male characteristics are never expressed. They live their lives as girls and then women, and a few can even give birth.
Which sperms are faster?
According to the hypothesis, male (Y) sperm are faster but more fragile than female (X) sperm. Further, acidic environments harm Y sperm, according to the theory, making conception of a girl more likely The Shettles method aims to exploit these two factors.
Can a man have only Y chromosomes?
Males have one Y chromosome and one X chromosome, while females have two X chromosomes. In mammals, the Y chromosome contains a gene, SRY, which triggers embryonic development as a male. The Y chromosomes of humans and other mammals also contain other genes needed for normal sperm production.
Is Y chromosome male or female?
The Y chromosome contains a “male-determining gene,” the SRY gene, that causes testes to form in the embryo and results in development of external and internal male genitalia. If there is a mutation in the SRY gene, the embryo will develop female genitalia despite having XY chromosomes.
What does it mean when you have an extra Y chromosome?
The extra X and/or Y chromosome can affect physical, developmental, behavioral, and cognitive functioning. Common physical features may include tall stature, lack of secondary pubertal development, small testes (hypogonadism), delayed pubertal development, and breast development (gynecomastia) in late puberty.
