What does an egg contribute to the embryo that sperm does not?
An egg contributes the majority of the genetic material (chromosomes) needed for the embryo, as well as organelles like mitochondria for energy production. Sperm only provides genetic material.
True or false human sperm and egg cells have 23 chromosomes?
True. Sperm and egg cells are gametes, and thus are necessarily haploid. These haploid gametes were created through the process of meiosis. When the two fuse to create an embryo, the new embryo will then have 46 chromosomes, the full number for a human. The embryo will receive one copy of each chromosome from each parent. If sperm and egg cells were to have the full set of 46 chromosomes, with both copies of each chromosome from each parent, then when they fused the embryo would have 92 chromosomes total. And the progeny of that embryo would have an even higher number of chromosomes. Having haploid gametes is necessary to maintain the stability of the species.
What does an egg contribute to the embryo that sperm does not contribute?
A period.
What does a sperm cell contribute to an embryo?
A sperm cell contributes half of the genetic material needed for the embryo, including the father's DNA. Additionally, the sperm cell's mitochondria are typically discarded during fertilization, so the embryo mainly relies on the egg cell for its cellular organelles.
What does an egg contribute to the embryo that a sperm cell does not?
An egg contributes the majority of the genetic material needed for the embryo to develop, including the mitochondria for energy production. In contrast, a sperm cell provides only half of the genetic material necessary for embryo formation.

How many chromosomes are found in human egg and sperm cell?
There are 23 chromosomes in each the sperm and the egg. When they fuse, the resulting embryo will have 46 chromosomes.

How many chromosomes from each egg and sperm?
There are 23 chromosomes from the egg and 23 chromosomes from the sperm making it 46 in total when they both fuse together.

How many chromosomes are in a human sperm Cell?
23 singles. Actually, for the astute, there are 22 autosomes and one sex chromosome.
What does the embryo get half from the female and half from the male?
The embryo receives half of its chromosomes from the female's egg and half from the male's sperm. This genetic material combines to form the unique set of DNA that determines the embryo's traits and characteristics.
In the whitefish how many chromosomes are there in a single set?
There are 40 chromosomes in a sperm cell of a white fish because the original number of chromosomes in a body cell is 80. Since the sex cells ( sperm and egg) each must contribute a set of chromosomes to the offspring, the sperm and egg both must have 40 chromosomes so they when the sperm and egg join or combine in a process known as fertilization, the offspring will have 80 chromosomes.
How many sex chromosomes does a sperm carry?
Each parent donates 23 chromosomes to fertilization process however only the male can determin the sex.
Hom many chromosomes does each human cell have?
There are 46 chromosomes in each cell. However, there are 23 in a sex cell e.g. 23 in an egg cell, 23 in a sperm cell to form 46 chromosomes for a embryo to develop.
