An embryo can split into two separate embryos during the early stages of development, typically within the first two weeks after fertilization. This process is known as twinning. In rare cases, splitting can occur later in development, up to around 13 days after fertilization.
Endosperm formation is triggered by fertilization because it involves the fusion of the two sperm cells with different nuclei in the embryo sac, leading to the triploid (3n) condition necessary for endosperm development. Without fertilization, the endosperm would not receive the necessary genetic contribution to develop properly and support the growing embryo.
No, periods do not occur after an egg is fertilized because fertilization of the egg leads to the development of the embryo, which implants in the uterus and eventually grows into a fetus. This process suppresses the shedding of the uterine lining that occurs during menstruation.
Fertilization occurs in the fallopian tube when a sperm cell fertilizes an egg cell. After fertilization, the zygote travels to the uterus where it implants into the uterine lining for further development. Embryonic development continues in the uterus until birth.
After puberty, the ovaries release one egg each month alternatively. The sperms enter through the vagina, travel upwards to the oviduct where they encounter the egg. If the egg is fertilized, a zygote is formed. The zygote repeatedly divided to form the embryo. This embryo trickles down to the uterus. On the uterine wall, the embryo gets implanted. The embryo gets nutrition form a special disc shaped tissue towards the uterine wall called the placenta. It contains villi on the embryo's side and provides nourishment and oxygen from the mother's blood. Waste substances such as carbon dioxide and nitrogenous wastes are taken away from the embryo. After the 9 month gestation period, the child is delivered as a result of rhythmic contractions of the uterus.

Endosperm formation is triggered by fertilization because it involves the fusion of the two sperm cells with different nuclei in the embryo sac, leading to the triploid (3n) condition necessary for endosperm development. Without fertilization, the endosperm would not receive the necessary genetic contribution to develop properly and support the growing embryo.
Fertilization in animals can occur inside or outside their body. It involves the sperm to fertilize with egg to form zygote. Then it goes rapid multiplication to form embryo. The embryo then slowly develops into baby.
No, periods do not occur after an egg is fertilized because fertilization of the egg leads to the development of the embryo, which implants in the uterus and eventually grows into a fetus. This process suppresses the shedding of the uterine lining that occurs during menstruation.
The maximum time for an embryo to implant after fertilization is typically around 6 to 10 days. After fertilization, the embryo travels down the fallopian tube and enters the uterus, where it can implant into the uterine lining. Delayed implantation can occur in some cases, but it generally does not exceed 10 days post-fertilization for successful implantation to take place.
Fertilization of the egg does not occur during the birth process. Birth is the process of delivering a baby from the mother's womb, which happens after fertilization, implantation, and gestation have already occurred.
After fertilization, the zygote is formed, which is the initial stage of a new organism. The zygote undergoes rapid cell division to form an embryo. Changes in gene expression and cell differentiation occur, leading to the development of tissues and organs. Eventually, the embryo develops into a fully formed fetus.
The changes that occur from fertilization of the egg until death are referred to as the lifecycle or life cycle. This encompasses all stages of development, growth, reproduction, and eventual death in an organism.
Fertilization occurs in the fallopian tube when a sperm cell fertilizes an egg cell. After fertilization, the zygote travels to the uterus where it implants into the uterine lining for further development. Embryonic development continues in the uterus until birth.
Turner's occurs in situ, usually very early in the development of the embryo.
After puberty, the ovaries release one egg each month alternatively. The sperms enter through the vagina, travel upwards to the oviduct where they encounter the egg. If the egg is fertilized, a zygote is formed. The zygote repeatedly divided to form the embryo. This embryo trickles down to the uterus. On the uterine wall, the embryo gets implanted.
