offspring had red flowers, but some had white. This was because the allele for red flowers is
dominant, and the allele for white flowers is recessive. Genetic diagrams help to show how
this works. In a genetic diagram, you show all of the possible alleles for a particular…

61. How is cystic fibrosis passed on?

Cystic fibrosis is an inherited disorder that affects the cell membranes, causing the
production of thick and sticky mucus. It is caused by a recessive allele. This means that it must
be inherited from both parents. The genetic diagram shows how…
