Question

What genes are inherited from the mother only?

Answer 1

It's simple to imagine a baby's genetic makeup as 50 percent mother and 50 percent father. In truth, it's a little more complicated. Learning a little about how genetic traits are inherited will help you understand why parents are accountable for particular behaviours.

Complete answer:
Our mitochondrial DNA makes up a modest percentage of our overall DNA. Only 37 of our body's 20,000 to 25,000 protein-coding genes are found there. However, it differs from DNA in the nucleus. Unlike nuclear DNA, which is inherited from both parents, mitochondrial DNA is inherited exclusively from the mother.

Nobody knows why or how mitochondrial DNA from fathers is deleted from cells. To find answers, an international team of scientists looked at mitochondria in the sperm of a roundworm called C. elegans.

In humans and most multicellular organisms, the transmission of mitochondrial DNA from mother to offspring, often known as maternal inheritance, happens. Maternal inheritance is what allows 23andMe and other genetic testing organisations to trace our maternal ancestors. Your mitochondrial DNA was inherited from your mother, who inherited it from her mother, and so on.

In terms of genetics, you have more of your mother's genes than your father's. This is due to the mitochondria, which are little organelles that exist within your cells and are exclusively given to you by your mother.

We inherited the following from our mother are-
- Intelligence.
- Hemophilia and autism.
- Height.
- Eye colour.
- Curly hair

Girls inherit two X chromosomes, one from their mother and one from their father. This means that your daughter will receive both her father's and mother's X-linked genes. Is it true that if your daughter inherits his X chromosome, she would receive all of his X-linked genes and traits? Yes, there are genes.

Note: The majority of human features are polygenic, meaning they are influenced by a combination of genes from both parents. There are at least 700 sequences in your genetic code that can influence height, for example. Similarly, the colour of your skin, hair, and eyes is determined by a jumble of genes, which explains why our eyes have such a diverse range of colours.
