– Requires 2 parents – two parents cells (egg, sperm) are joined to form offspring that are different from parents. – Cell division in which 4 cells are produced at the same time with half the number of chromosomes as parents cells.

Sexual reproduction consists of a set of events and can be divided into three stages: Pre-fertilization, Fertilization, and Post-fertilization.

Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are (1) liberation of an ovum, or egg, at a specific time in the reproductive cycle, (2) internal fertilization of the ovum by spermatozoa, or sperm cells, (3) transport of the fertilized ovum …

Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.

If one sperm does make its way into the fallopian tube and burrows into the egg, it fertilizes the egg. The egg changes so that no other sperm can get in. At the instant of fertilization, your baby’s genes and sex are set. If the sperm has a Y chromosome, your baby will be a boy.

Some women do notice signs and symptoms that implantation has occurred. Signs may include light bleeding, cramping, nausea, bloating, sore breasts, headaches, mood swings, and possibly a change in basal body temperature.

Answer Expert Verified A few days after fertilization implantation happens. Implantation is the attachment of the fertilized egg to the uterus, happens on average about 9 days after ovulation/fertilization (between 6 and 12 days) and is required for the fetus to continue to grow.

The fertilised ovule goes on to form a seed, which contains a food store and an embryo that will later grow into a new plant. The ovary develops into a fruit to protect the seed.

Answer Expert Verified The calyx is that part of the flower which is attached to the stem. After fertilization mostly the calyx falls off as its function of protecting the flower or its reproductive parts is over. Otherwise it dries up or becomes shrivelled.

In this process, the female and the male gamete merge to produce a diploid zygote. A series of post fertilization events take place in the zygote, and a seed develops. The formation of the seed occurs in the ovule a fruit develops, inside an ovary that forms in flowers.

Can you feel when an egg gets fertilized? You won’t feel when an egg gets fertilized. You also won’t feel pregnant after two or three days. But some women can feel implantation, the process in which the fertilized egg travels down the fallopian tube and buries itself deep within the wall of the uterus.

Spotting and Cramping After conception, the fertilized egg attaches itself to wall of the uterus. This can cause one of the earliest signs of pregnancy — spotting and, sometimes, cramping.

A person can get pregnant 12–24 hours after ovulation, as a released egg can survive up to 24 hours within the cervix. For those trying to conceive, it is crucial to understand the menstrual cycle.

But the most fertile days are the three days leading up to and including ovulation. Having sex during this time gives you the best chance of getting pregnant. By 12-24 hours after ovulation, a woman is no longer able to get pregnant during that menstrual cycle because the egg is no longer in the fallopian tube.

Around eight days after ovulation, trace levels of hCG can be detected from an early pregnancy. That means a woman could get positive results several days before she expects her period to start.

4 DPO is a very early stage in your cycle’s luteal phase, or time after an egg is released. If the egg released during ovulation is fertilized, it’s an early step toward becoming pregnant. If the egg was fertilized by a sperm cell when you ovulated, the fertilized egg will transform into a zygote.

Days 7–10 past ovulation When the fertilized egg implants itself in the uterus, around one-third of women will notice light bleeding or spotting, which is called implantation bleeding. This spotting typically lasts only a day or two and is very light in flow.

Cramping at 3 DPO as a sign of early pregnancy may be possible, but it’s not typical for most people. This is because a fertilized egg usually does not implant in the uterine lining until about 6–10 days after ovulation. This cramping tends to be minor and can be associated with some light spotting.

When does implantation occur? Implantation occurs about 8 to 9 days after fertilization, though it can happen as early as 6 days and as late as 12 days after ovulation.

Where Do You Feel Implantation Cramps? Many women detect implantation cramping in their lower abdomen and lower back. Sometimes cramps only manifest on one side of the body.

How soon can you take a pregnancy test? You should wait to take a pregnancy test until the week after your missed period for the most accurate result. If you don’t want to wait until you’ve missed your period, you should wait at least one to two weeks after you had sex.
