Pedigree Chart For Free Or Attached Earlobes Answers
What Is A Pedigree Chart?
A pedigree chart is a diagram that shows the genetic relationships between family members over several generations. The chart is used to track the inheritance pattern of a particular trait or disease within a family. The chart consists of squares and circles that represent males and females, respectively, and lines that connect them to show their relationships.
What Are Free Earlobes?
Free earlobes are earlobes that are not attached to the side of the head. They hang freely from the earlobe and are not connected to the skin of the head. Free earlobes are the dominant trait, meaning that if one parent has free earlobes, their offspring will also have free earlobes.
What Are Attached Earlobes?
Attached earlobes are earlobes that are connected to the skin of the head. They do not hang freely like free earlobes. Attached earlobes are the recessive trait, meaning that if both parents have attached earlobes, their offspring will also have attached earlobes.
How Are Pedigree Charts Used To Determine Earlobe Traits?
Pedigree charts are used to track the inheritance pattern of earlobe traits within a family. If a family member has free earlobes, they are represented on the chart with a capital "F" in the square or circle. If they have attached earlobes, they are represented with a lowercase "f".
To determine the probability of a child inheriting free or attached earlobes, the chart is used to track the genetic makeup of the parents. If both parents have free earlobes, their child will also have free earlobes because the trait is dominant. If both parents have attached earlobes, their child will also have attached earlobes because the trait is recessive. If one parent has free earlobes and the other has attached earlobes, the child's earlobe trait will depend on the specific genetic makeup of the parents.
Conclusion
A pedigree chart is a useful tool for tracking the inheritance pattern of genetic traits within a family. By using the chart to track the genetic makeup of parents, it is possible to determine the probability of a child inheriting a particular trait, such as free or attached earlobes. Understanding the inheritance pattern of traits can help individuals make informed decisions about their health and the health of their offspring.
