What makes up a DNA?
When a man and a woman have a baby, in the man's sperm there is one set of genes and in the woman's egg there is only one set of genes wheras with every other cell in your body there are two sets of genes. Your last set of genes determines if you are a boy or a girl, if you are XX, you are a girl, if you are XY, you are a boy. Hope this helps.
What cell does every human being begin life as?
Every human being begins life as a single cell known as a zygote, formed through the union of an egg cell and a sperm cell during fertilization.
Why would placing a cell nucleus inside a nucleus- free egg cell enable the egg to begin dividing?
Placing a cell nucleus inside a nucleus-free egg cell enables the egg to begin dividing because the introduced nucleus carries the genetic information necessary for cell division. The nucleus contains the DNA that instructs the egg cell to start dividing and developing into an embryo. This process, known as somatic cell nuclear transfer, reprograms the egg cell to start cell division by activating the genes in the introduced nucleus.
When a cell such as an egg or sperm only contains one copy of each pair of chromosomes from the parent cell you call this chromosome number?
haploid.
What is a non-example for a haploid cell?
A diploid cell is one that has two copies of its genetic information. Each copy is from a different parent. For example,All of the cells in your body (muscle, bone, brain, eye, etc.) are diploid. A haploid cell is one that has a single copy of its genetic information. For example, sperm and egg cells are haploid.
The gamete that contains genes contributed only by the mother is?
The egg cell or ovum contains genes contributed only by the mother. During fertilization, the egg cell combines with a sperm cell, which contributes genes from the father, to form a zygote with genetic material from both parents.
How much of parents genes does an egg or sperm cell have?
half
Do all Cells have a full set of genes in their Nuclei?
Yes. Every Cell in the body, with the exception of egg and sperm Cells, has a complete set of the genes [chromosome pairs] in its nucleus and are thus diploid. The egg and sperm Cells have only half of a 'Set of Chromosomes' and are thus haploid.
Can 2 lesbians have a baby with both their genes?
No, as one half of a baby's genes must come from an egg cell and the other half must come from a sperm cell.
What process is when sperm and egg cell receives all of its genes at once?
process of pregnancy
What is a sperm cell main function?
sperm main function is to carry the male genes to the egg
What role does genes play in life science?
there are 23 chromosomes in an egg and sperm cell these then combine

What is the biological requirement for reproduction for male and female?
The male produces sperm cells, which carry his genes. The sperm cell meets an egg cell from the female which carries her genes. The sperm cell penetrates the egg's outer layer. This is called "fertilizing" the egg. Normally, the outer layer of the fertilized cell thickens, so no more sperm cells can enter it. The fertilized egg then travels to the woman's uterus, where it attaches to the wall of the uterus and ultimately develops into a fetus.
The gamete that contains genes contributed only by the mother?
The egg is the gamete produced by the female.
What cell does every human being begin life as?
Every human being begins life as a single cell known as a zygote, formed through the union of an egg cell and a sperm cell during fertilization.
