hey i need help for some of these questions and on pedigree with the help of this story......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:
1. Who are the in-laws?
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 squares using the information below. Remember that individuals who possess the RECESSIVE trait are to be filled in completely. Individuals not shaded in carry at least one dominant allele.
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.
Using the guide provided, determine the genotypes of all individuals in this pedigree chart for freckles. Remember, having no freckles is a RECESSIVE trait.
thank U :)
We're all lazy sad sacks.
Oh crap, these are from like, 7 to 10 years ago. Well then. I still need help LOLOLOLOL I'm losing my mind as is :))))
i got this project too. can u help
why isnt anyone answering??? its not that hard .
\wh
To answer the first question, we need to identify the in-laws in the story. In-laws refer to the spouses or partners of the family members. Based on the information given, the in-laws are:
1. Elizabeth's husband, David.
2. Fred's wife, Wilma.
3. Mickey's wife, Monica.
Now let's move on to the second question, which asks about the relationship between the people in the third generation. In this story, the third generation includes the grandchildren. The relationships between the individuals in the third generation are as follows:
1. John and Sonny are twins.
2. Krista and Janet are sisters.
Now, for the part where we determine the genotypes of individuals in the pedigree for freckles.
We are told that not having freckles is a recessive trait. Grandpa Flipnob did not have freckles, but his wife did, so we can infer that Grandpa Flipnob carries at least one dominant allele for freckles.
Fred and Michelle are the only two siblings to have freckles. This implies that both Fred and Michelle carry at least one recessive allele for freckles.
Based on this information, we can determine the genotypes for each individual in the pedigree as follows:
- Grandpa Flipnob: Genotype - Ff (carries one dominant allele and one recessive allele for freckles).
- Grandma Flipnob: Genotype - ff (has two recessive alleles for freckles).
- Elizabeth: Genotype - Ff (carries one dominant allele and one recessive allele for freckles).
- Fred: Genotype - FF or Ff (has either two dominant alleles or one dominant and one recessive allele for freckles).
- Michelle: Genotype - ff (has two recessive alleles for freckles).
- Mickey: Genotype - FF or Ff (has either two dominant alleles or one dominant and one recessive allele for freckles).
- John (twin): Genotype - ff (has two recessive alleles for freckles).
- Sonny (twin): Genotype - ff (has two recessive alleles for freckles).
- Barney: Genotype - FF or Ff (has either two dominant alleles or one dominant and one recessive allele for freckles).
- Krista: Genotype - ff (has two recessive alleles for freckles).
- Janet: Genotype - ff (has two recessive alleles for freckles).
Remember, lowercase letters (ff) represent recessive alleles, while uppercase letters (Ff, FF) represent dominant alleles.
I hope this helps you understand how to answer these questions and determine the genotypes for freckles in the pedigree chart! Let me know if there's anything else I can assist you with.
