Question

The pedigree chart below shows the individuals in a family who exhibit a certain trait. Based on the information in the chart, which of the following provides the best evidence that this is a recessive trait?

Answer 1

You did not provide us with any chart. However, determining a recessive trait is very straightforward, you have to look for traits that can be carried on from parent to offspring and that happen very often. As recessive traits most often become apparent when both parents are heretozygotous and can pass one the recessive trait to their offspring.
