Chromosomes are made up of DNA, which is the genetic material that contains the instructions for how the body grows and functions.<\/p>\n<p>The 46 chromosomes are divided into 23 pairs. 22 of these pairs are called autosomes, and the remaining pair is called the sex chromosomes. Females have two X chromosomes, while males have one X chromosome and one Y chromosome.<\/p>\n<p>The number of chromosomes in a cell can vary depending on the type of cell. For example, sperm cells and egg cells only have 23 chromosomes each. This is because when a sperm cell fertilizes an egg cell, the resulting cell (a zygote) has 46 chromosomes.<\/p>\n<p>The number of chromosomes in a cell can also change due to a genetic disorder. For example, people with Down syndrome have an extra copy of chromosome 21.<\/p>\n<p>Chromosomes are important because they contain the genetic information that determines a person&#8217;s physical characteristics, such as hair color, eye color, and height. They also play a role in determining a person&#8217;s risk of developing certain diseases.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;42&#8243; option2=&#8221;44&#8243;
