Genes are the basic unit of heredity and are passed on from parents to their children. Genes are responsible for determining physical characteristics, such as hair and eye color, as well as influencing other characteristics, such as intelligence and personality. While most genes are inherited from both parents, some genes are only passed on from the father.
The X and Y chromosomes are responsible for determining a child’s gender. Females have two X chromosomes, one inherited from the mother and one from the father. Males have one X chromosome from their mother and one Y chromosome from their father. Therefore, all gender-linked traits, such as sex-specific physical characteristics, are inherited from the father.
In addition, some diseases are determined by a single gene and can only be passed on from the father. For example, Duchenne muscular dystrophy is caused by a mutation in a gene found on the X chromosome. Because females have two X chromosomes, they can have one normal and one mutated X chromosome. If they have a mutated X chromosome, they may be carriers of the disease, but they will not display any symptoms. However, males only have one X chromosome, so if they have a mutated X chromosome they will show symptoms of the disease.
In conclusion, genes inherited from the father can determine the gender and some medical conditions of a child. It is important to remember that a child’s physical and personality traits are determined by a combination of genes from both parents.
