What is a chance that a human zygote will receive one x and one y sex chromosome during fertilization?
The chance is 50%.
What alleles are received during fertilization?
During fertilization, an individual receives one allele for each gene from each parent. This means that a person inherits one allele for each gene from their mother and one allele from their father. The combination of alleles received determines the individual's genotype for that particular gene.
What is a developing human known as during the first eight weeks after fertilization?
A developing human during the first eight weeks after fertilization is known as an embryo.
What type of fertilization do toads have?
Toads have external fertilization. During mating, the male toad releases sperm onto the eggs as the female lays them.
What is the union of a reproductive cell from a male and one from a female called?
The union of a reproductive cell from a male (sperm) and one from a female (egg) is called fertilization. During fertilization, the genetic material from both cells combines to form a new individual with a unique set of genes.
Why are there more egg and sperm cells produced during external fertilization than during internal fertilization?
Why are there generally more eggs and sperm cells produce during external fertilization thean internal fertilization
Does sperm always reach the egg during fertilization?
No, sperm does not always reach the egg during fertilization. Only one sperm typically fertilizes the egg, while the rest are blocked from entering.
What unites during fertilization?
During fertilization the sperm unites with the egg. This typically occurs in the fallopian tube.
What is the chance a human zygote will receive one X and one Y chromosome during fertilization?
The chance is 50%.
Where does fertilization takes place in human?
In humans, fertilization occurs in the ampulla of the uterine tube. During fertilization the sperm and the egg become one and become what is called a zygote.
What is the chance that human zygote will receive one X and one Y sex chromosome during fertilization?
The chance is 50%.

What prevents multiple sperm from fertilizing one egg during the process of fertilization?
During fertilization, the egg releases chemicals that prevent other sperm from entering once one sperm has successfully fertilized it. This process is called the zona reaction, which helps ensure that only one sperm can fertilize the egg.
What is the chemical released by sperm during fertilization?
The chemical released by sperm during fertilization is an enzyme called acrosin. Acrosin helps the sperm penetrate the protective layer around the egg, facilitating fertilization.
What happens if two sperms enter one egg during fertilization?
When two sperms enter one egg during fertilization, it results in an abnormal number of chromosomes in the resulting embryo. This typically leads to a nonviable pregnancy, meaning the embryo is unable to develop properly and the pregnancy will not continue.
Is fertilization possible during menstruation?
Not the least
