Pedigree Chart Activity Worksheet (Page 3 of 4) in pdf

Generations should be numbered at the left of the chart (using Roman numerals). This simplifies any

explanations you will make.

Number each individual in a generation from left to right (1,2...) to again simplify explanations.

Now, follow the story, and make the appropriate pedigree chart.

This is the story of Grandma and Grandpa Flipnob, and their clan! They were married way back in 1933, and have been just like

newlyweds ever since. From their union, 4 individuals were created. Elizabeth, the eldest, was born in 1935. Fred soon followed in

1936. In 1939 Michelle was brought into this world. Mickey (a surprise to the whole family was the baby of the family, not being born

until 1950.

Elizabeth fell in love at a young age, and wed her high school sweetheart, David, in 1954. From this marriage, two bundles of joy

came about (at the same time):

John and Sonny - 1955 (twins)!

It took Fred a little longer to find his soul mate. Finally in 1970, Fred found the woman of his dreams, Wilma, and they were married.

Since they married so late in life, they only brought one new person into this world:

Barney - 1972

Michelle was a hard working woman, and never found time in her schedule for love. She led a very productive and fulfilling life, but

she never did marry and have children.

Mickey was a wild one!! After a long string of girlfriends, he finally chose Monica to spend the rest of his life with. They were wed in

1975 and brought two girls into this world:

Krista - 1977

Janet - 1979

Answer the following questions regarding your pedigree:

1. Who are the inlaws?

2. What is the relationship between the people in the third generation?

Now that you have your pedigree chart together, shade the appropriate circles and squared from the information to follow. Remember

that individuals who possess the RECESSIVE trait are to be filled in. Those individuals not filled in possess at least one dominant

trait.

Dominant/Recessive Inheritance - Freckles

Not having freckles is a recessive trait.

Grandpa Flipnob did not have freckles, but his beautiful bride did.

Fred and Michelle were the only two of their siblings to have freckles.

Of the grandchildren, the twins did not have freckles, and neither did Barney, but the two girls did.
