Baby mice have been made with two mums and no dad, say researchers at the chinese academy of sciences. However, it is not unusual for two parents who have blue eyes to have a baby with brown eyes.

The genetic differences between men and women lie in these sex chromosomes.
Can two females have a baby with the same genes. It has been suggested that the father's genetic interests are best served by producing the biggest, toughest baby, whatever the cost to the mother (you can always find another female to mate with). Researchers from cambridge university have found that it is possible to make a baby using cells from two same. "two men can't have a biological child, and two women can't have.
Women have two x chromosomes. If they are in perfect condition they will be in 23 pairs, making 46 in total. But what a new study from the chinese academy of sciences suggests.
If there are too many males in the population, for example, females will more easily find a mate, so men who have more daughters will pass on more of their genes, causing more females to be born. Babies born from two mothers survive for first time in mouse study. It demonstrates the same gene can cause two different phenomena, she says.
Throughout history, a child has come from a man and a woman. Even though women have two x chromosomes, only one is functional because the other is inactivated through a process. Women have two paired x chromosomes instead.
The same blueprint can result in a range of different homes that look quite similar but have important differences based on the material and color choices used during construction. Genes are held within chromosomes. However, your child can have blue eyes if one of you has a genetic link, down the family tree.
The interaction of the gene with other genes and the continual interaction. He's our miracle baby, said ashleigh coulter. So could such a technique potentially enable two women to have a biological baby?
Females have two x chromosomes and no y's, while males have one x and one y. Some genes can only be passed on by the mother and some things can only be passed to boys and some only to girls. A baby will inherit half its genes from its mother.
Genes are the elements that determine the structure of the body. There are a couple different possible methods for getting around the issue of imprinting to create a baby from two. Gene expression whether or not a gene is expressed depends on two different things:
It took a substantial feat of genetic engineering to break the rules of reproduction. In addition, females have two x chromosomes and males have one x and one y chromosome. A larger x chromosome paired with a smaller y chromosome.
For chromosomes 1 through 22, the two members of the pair appear identical. Genetically, if you have blue eyes and your baby's father has dark eyes, your child has higher chances of having brown eyes. Generally, active genes from the father directly or indirectly promote growth, whereas active genes from the mother suppress growth.
After conception (when a sperm cell and an egg come together to make a baby), the chromosomes duplicate again and again to pass on the same genetic information to each new cell in the developing child. Everyone knows it takes a male and a female to make a baby.
