The probability of inheriting almost any trait can be predicted if the genetic makeup of the parents is known. The likelihood of both good and bad traits showing up in the phenotype can be determined using Punnett squares., If two people who are both carriers for a genetically inherited fatal recessive disease decide to become parents, there will be a 50% chance of having a carrier child. Similarly, each time there will be a 25% chance of having an offspring who will inherit the disease and die., Phenotype is the observable characteristics, including physical appearance. It results from the genotype and environmental influences. A phenotype includes not only easily measured traits like hair color but also less apparent ones such as blood type..
