Answer 1

Genetic diseases are normally divided into two types those are recessive and dominant genes, those in recessive genes require both parents to be carrying the defective gene, otherwise the healthy gene from one parent overrides the unhealthy gene from the other parent. This type of gene can mean there are a lot of carriers of the recessive gene in the population without knowing it. The dominant gene means that the parent will have the condition and is far more likely to pass it on to the child, due to the disadvantages with having the gene these tend to be rarer. https://youtu.be/GTqXdraHe3E
