Why does an embryo with 2 X chromosomes develop into a female?
An embryo with 2 X chromosomes develops into a female due to the presence of genes on the X chromosomes that promote the development of female reproductive structures and characteristics. These genes lead to the production of hormones that guide the development of female features during prenatal development.
When do milk ducts develop in the female breast?
Milk ducts in the female breast develop during puberty.
At what week in fetal development does the genetic instructions for differential development of male or female gonads occur?
The genetic instructions for differential development of male or female gonads occur around the 7th week of fetal development. During this time, the presence or absence of the Y chromosome determines whether the gonads will develop into testes (male) or ovaries (female).
What is the sit of the embryo development?
Embryo development occurs inside the uterus of a female reproductive system. The uterus provides a protective environment for the embryo to grow and develop during pregnancy, receiving nourishment and support from the mother's body.
During gestation embroyos normally develop in?
Embryos normally develop in the uterus of the female reproductive system. The uterus provides a safe and nourishing environment for the embryo to grow and develop during gestation.
When does the development of female gametes begin?
The development of female gametes, known as oocytes, begins during fetal development. The process starts before a female is born, and reaches a peak number of oocytes around the fifth month of prenatal development. However, oocytes remain in an arrested state of development until a woman reaches puberty.

Why do female children are more likely to act like tomboys if they were exposed to excess what duringf their prenatal development?
high levels of testosterone

Does the male and female reproductive system develop from the same tissues in the embryo?
Yes, both the male and female reproductive systems develop from the same tissues in the embryo called the genital ridges. The presence or absence of certain hormones during development will determine the differentiation into either male or female reproductive structures.
A zygote will develop into a female if the?
A zygote will develop into a female if it receives two X sex chromosomes from the parents during fertilization.
What is the sit of the embryo development?
Embryo development occurs inside the uterus of a female reproductive system. The uterus provides a protective environment for the embryo to grow and develop during pregnancy, receiving nourishment and support from the mother's body.
When does oogenesis begin in which stage of female growth and development?
Oogenesis begins during fetal development, specifically during the development of the ovaries in the fetus. It is the process by which female gametes (egg cells) are produced in the ovaries.
What happens during a prenatal visit to a doctor or certified nurse midwife?
During the doctor visit, the female will have a complete physicalthat includes blood tests and a pelvic exam.
Will progesterone develop secondary sexual organs at puberty in a female?
No, progesterone does not play a significant role in the development of secondary sexual organs in females during puberty. The primary hormones involved in the development of secondary sexual characteristics in females are estrogen and testosterone.
During gestation embroyos normally develop in?
Embryos normally develop in the uterus of the female reproductive system. The uterus provides a safe and nourishing environment for the embryo to grow and develop during gestation.
