Two parents learn they are each carriers for Cystic Fibrosis, each having the genotype (Aa). Using a punnett square, perform a genetic cross to determine the probability that their children will inherit two recessive alleles and have Cystic Fibrosis (aa).   In your answer, explain the probability using either percentages (%) or odds out of 4 (1/4, 3/4, etc).

Jill has a son named Jack. She claims that James is the father. James denies this. Jill has Type A blood. Jack has Type O blood. James has Type B blood. Based on this information, what would a court decide on this problem?   Question 3 options:   James could be the father of Jack because James could be heterozygous   James is not the father of Jack because their phenotypes are different   James is not the father of Jack because their genotypes are different   James could be the father of Jack because type B blood is usually I^Bi   James is the father of Jack because he passed on a recessive allele

Cystic Fibrosis is an autosomal recessive disorder. A couple are both carriers of the recessive allele (both heterozygous (Cc)) and have the normal wild-type phenotype. What is the probability of the following occurring; If they have two children, what is the probability of them both being unaffected (CC or Cc) by the disease?

State the name of the analysis/ chart and explain in at least one sentence. Question #2 Which of Mendel's postulates can only be demonstrated in crosses involving at least two pairs of traits? State the postulate and explain in at least one sentence. D. Focus Question #3

Uncle Smiley, who is heterozygous for a yellow face (Yy), married a woman with a green face. Both of them have always wanted a large family. If they were to have 12 children, what is the probability that the children would have yellow faces? How many would have green faces? Create a Punnett square to help you find your answers.

The allele for freckles (F) is dominant to the allele for no freckles (f). A freckled man and an unfreckled woman have two children, a boy with freckles and a girl without freckles. What are the genotypes for all four?   Question 6 options:   Mom: XfXf, Dad: XY, boy: ff, girl: ff   Mom: ff, Dad: FF, boy: Ff, girl: ff   Mom: ff, Dad: Ff, boy: Ff, girl: ff   Mom: ff, Dad: FF, boy: Ff, girl: FF

The diagrams represent two human somatic cells, one from a female and one from a male, and the letters in the cells represent alleles for two different traits.           Male                             Female          B = Brown hair (dominant)          b = Blond hair (recessive) E = Brown eyes (dominant)         e = Blue eyes  (recessive)                                                                                                   According to Mendel’s Law of Independent Assortment, what are the allele combinations expected in each of the sperm cells and what combinations are expected in each of the eggs produced by these cells during meiosis? One sperm fertilized one egg, and the resulting child has blond hair and brown eyes. How is this possible given the parents' genotypes?

Mr. and Mrs. Flynn are concerned because their new baby doesn't resemble either of them and has type O blood. Mr. Flynn is type A and Mrs. Flynn is type B. They're sure that it's impossible to have a baby with a different blood type than the parents, and so they conclude that a mistake has been made. Are they correct? Explain your answer. Be specific. Use the correct blood alleles (IA, IB, i) in your explanation.   genotypes:   Mr. Flynn _________         Mrs. Flynn __________           their baby ___________ Display keyboard shortcuts for Rich Content Editor

Below is a pedigree chart for a family that has a history of Alkaptonuria.   Individuals infected with this condition can have darkened skin, brown urine, and can suffer from joint damage and other complications.  Given this pedigree answer the following questions.   Given the data in the pedigree chart is this genetic condition autosomal dominant or autosomal recessive? What are the genotypes for #1, #2, and #3?  If either of the 4th generation "aa" females were to mate with a homozygous dominant male would any of their offspring illustrate the phenotype?  Why or why not?
