They have a son, Les, who is a healthy nine-year-old with myopia (nearsightedness) but no sign of galactosemia.Jane’s mother, Hilda, is alive and healthy; Jane’s father, Henry, passed away last year of a sudden heart attack. Hilda and Henry have no family history of galactosemia.Use the information in the family history to construct a pedigree for this family.

Answer 1

Pedigree is the symbolic representation of the history of an individual's family connections, presenting their ascendants and descendants in an organized manner. This is an important instrument in the genealogical process, as it is a way of gathering data about the ancestors of the members who participated in a person's family building so that the connections between these individuals are established.

The family pedigre shown in the above question would be:

Hanna's mother and Hanna's father have three daughters of Hope's order, Holly and Hanna. Hanna and Harry have a son named John. John is married to Jane. His children are Lee and Leah (diagnosed with galactosemia ). Janes's mother is Hilda and the brother is Joe. Joe is married to Jen and his son is Les.

Answer 2

Answer:

The image with the answer is attached.

Explanation:

When drawing a pedigree in genetic the circle represents a woman, square represents a man, any square or circle with a line in the middle means that the person passed away, a colored circle or square indicates the one that is affected with the trait (in this case galactosemia), The line that connects a square and a circle indicates that those two people are married.

Pedigrees are very useful to determine if there is anyone else in the family with that trait or who will carry that trait in the future.
