A woman’s fertility may be impacted by a gene she inherited from her father, according to a study published in Science. In a normal egg cell, a part of the cell called the centrioles is eliminated as part of the natural development process. However, if the centrioles aren’t eliminated – often due to a genetic dysfunction, passed on by her dad – then the woman is sterile, researchers explained.
You may have heard that how and when a man loses his hair is due to an inherited trait from his mum’s side. However, a study, published in PLoS Genetics, of over 55,000 men has proved this to be a myth. Researchers found 287 independent genetic signals that were linked to male-patterned hair loss and while 40 were only found on the X chromosome, meaning they were inherited on the maternal side, the rest were scattered throughout DNA inherited from both patterns. Interestingly, some genes associated with hair loss also seem to be associated with an increased risk for heart disease in men. While some traits are inherited, others are learned.
