What would happen if a diploid sperm fertilized a diploid egg?
If a diploid sperm fertilizes a diploid egg it will produce a blank zygote. … That means generally sperm and egg only have one set of chromosomes. Whenever we look at sperm and egg they're only going to have one set of chromosomes because they are haploid. That means that they have one of each chromosome.
What would happen if sperm and egg cells were diploid?
Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
Is fertilization diploid to diploid?
Sexual life cycles involve an alternation between meiosis and fertilization. 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.
Is a diploid cell formed when sperm fertilizes egg?
Yes, a diploid cell called a zygote is formed from fertilization.
What is the end result of meiosis diploid eggs diploid sperm diploid gametes haploid gametes haploid zygotes?
What is the end result of meiosis? How do haploid gametes result in diploid offspring? A haploid egg and a haploid sperm fuse to form a diploid zygote that grows by mitosis after fertilization.
Are sperm and eggs haploid or diploid?
haploid Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.
What happens when a haploid sperm and egg cell are joined together?
Through fertilization, the egg and sperm are saved: the egg is activated to begin its developmental program, and the haploid nuclei of the two gametes come together to form the genome of a new diploid organism.
What happens when a sperm fertilizes an egg?
If a sperm cell does join up with your egg, the fertilized egg moves down the fallopian tube toward the uterus. It begins to divide into more and more cells, forming a ball as it grows. The ball of cells (called a blastocyst) gets to the uterus about 3–4 days after fertilization.
Is egg haploid or diploid?
Haploid refers to the presence of a single set of chromosomes in an organism's cells. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.
What are the results of fertilization?
The result of fertilization is a cell (zygote) capable of undergoing cell division to form a new individual. The fusion of two gametes initiates several reactions in the egg. One of these causes a change in the egg membrane(s), so that the attachment of and penetration by more than one spermatozoon cannot occur.

How do haploid gametes result in diploid offspring quizlet?
How do haploid gametes result in diploid offspring? A haploid egg and a haploid sperm fuse to form a diploid zygote that grows by mitosis after fertilization.
Which of the following has to occur if a diploid body has to produce haploid gametes?
A diploid parent plant body produces haploid gametes through reductional division, and a haploid parent plant body produces haploid gametes through reductional division (by equational division). So, option D is the correct answer.
What would have been happened if the male and female gametes had been diploid?
If the gametes of the male and female had been diploid then the zygote formed after fusion would have double the chromosomes of the gamete. This means the zygote would have ninety-two chromosomes. In other words, it would be tetraploid.
What is a fertilized egg called?
When a fertilized egg has implanted in the uterus, the group of cells that will become a baby is called an embryo. A developing, fertilized egg is known by several names within the first 2 weeks after conception, including zygote, morula (day 4), and blastocyst (day 5).
Is the cell that results from fertilization a haploid or diploid cell?
It is diploid. Fertilization involves two haploid cells joining together to form a zygote. For example, a sperm has 23 chromosomes and so does an egg. When they combine, the resulting cell is diploid.
What is a fertilised egg called?
When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus. The male reproductive system and the female reproductive system both are needed for reproduction.
Is sperm diploid or haploid?
Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.
What would have happened if the male and female gametes had been diploid?
If the gametes of the male and female had been diploid then the zygote formed after fusion would have double the chromosomes of the gamete. This means the zygote would have ninety-two chromosomes. In other words, it would be tetraploid.
What happens when the sperm fertilizes the egg?
If a sperm cell does join up with your egg, the fertilized egg moves down the fallopian tube toward the uterus. It begins to divide into more and more cells, forming a ball as it grows. The ball of cells (called a blastocyst) gets to the uterus about 3–4 days after fertilization.
What is the result of the fertilization of an egg quizlet?
Fertilization results when one egg and one sperm fuse to form a diploid zygote.
How do haploid gametes result in diploid individuals?
How do haploid gametes result in diploid offspring? A haploid egg and a haploid sperm fuse to form a diploid zygote that grows by mitosis after fertilization.
What problem would result if gametes were diploid?
If gametes were diploid, then the chromosome number would double with each generation. The two sets of homologous chromosomes come from DNA replication.
When a diploid plant produces only one kind of gamete as a result of meiosis then it is called?
If nondisjunction causes a missing chromosome in a haploid gamete, the diploid zygote it forms with another gamete will contain only one copy of that chromosome from the other parent, a condition known as monosomy.
What is haploid diploid?
Haploid refers to the presence of a single set of chromosomes in an organism's cells. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.
What problem would happen if gametes were diploid?
If both of the gametes were diploid, the zygote forming would then have four sets of chromosomes so it would be tetraploid instead of diploid.
Are male and female gametes haploid or diploid?
haploid cells They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.
What happens when an egg cell is fertilized?
If a sperm cell does join up with your egg, the fertilized egg moves down the fallopian tube toward the uterus. It begins to divide into more and more cells, forming a ball as it grows. The ball of cells (called a blastocyst) gets to the uterus about 3–4 days after fertilization.
