You asked: What if gametes were diploid?

What problem would result 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.

Can gametes be diploid?

Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous, or similar, copies of each chromosome. The only exception is cells in the germ line, which go on to produce gametes, or egg and sperm cells.

What would happen if reproductive cells were diploid?

Imagine what would happen if human gametes were made by mitosis: They would be diploid like the somatic cells. At the next round of fertilization, when two gametes fused, the normal chromosome number of 46 would double to 92, and each subsequent generation would double the number chromosomes yet again.

What could cause a gamete to become diploid?

Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

What might happen if the gametes of a species had the same number of chromosomes as the species body cells?

ANS: When the gametes fused during fertilization, the offspring would have more chromosomes in their body cells than their parents have. As a result, the species’ chromosome number would not be constant. … ANS: Mitosis produces diploid body cells, whereas meiosis produces haploid gametes.

Is gamete diploid or haploid?

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 would happen if meiosis in humans always produced diploid gametes?

Explanation: Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. … During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.

Why are gametes haploid and not diploid?

Gametes contain half the number of chromosomes of all other cells in the organism. This means they are haploid . When the male and female gametes combine in fertilisation they create an embryo with the full complement of chromosomes (diploid).

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 will happen when gametes are united?

During fertilization, a male gamete (sperm/spermatozoa) fuses with female gamete (egg/oocyte). … Gametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote.

Why is it important that haploid gametes be produced in animals?

Having haploid gametes is extremely important in most animal reproduction because if the gametes were diploid like the body cells of the parent, after…
