What are genetics explained by kids?
Genetics is the study of how genes and how traits are passed down from one generation to the next. Our genes carry information that affects our health, our appearance, and even our personality!
What genes does a child inherit?
One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.
Do genetics come from Mom or Dad?
Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.
What are 5 facts about genetics?
14 strange facts about your DNA
- Around 5-8% of your DNA isn’t human – it’s viral DNA.
- We share 96% of our DNA with primates such as chimpanzees, gorillas and orangutans.
- Around 99.9% of the DNA in all humans is identical.
- Humans have approximately 10 trillion cells.
What do mothers pass on to their daughters?
Mitochondrial inheritance, also called maternal inheritance, refers to genes in the mitochondria. Although these conditions affect both males and females, only mothers pass mitochondria on to their children. A father can never pass on a mitochondrial condition, because he does not pass on his mitochondrial genes.
Does intelligence run in families?
General intelligence definitely runs in the family. Twin studies (on both identical twins and fraternal twins) have found a heritability of IQ between 57% and 73%, and in some cases, even higher.
Can a child look nothing like either parent?
“Children in general do not look enough like their parents for a resemblance to be detected,” researchers from the University of California at San Diego report in today’s issue of the journal Nature, “with the one exception that one-year-olds look like their fathers.”

What are examples of genetics?
What Is Genetics? Genetics is the study of genes. Our genes carry information that gets passed from one generation to the next. For example, genes are why one child has blonde hair like their mother, while their sibling has brown hair like their father.
