Homework Answers
1.
Autosomal dominant
The given pedigree is autosomal because it is present in both males and females with an equal chance.
It is dominant because it is present in all the generations. Affected parents have affected progenies.
Normal = aa
Affected = AA or Aa
According to guidelines, only first question can be answered. Please give a good rating.

conditions
The pedigree from Part A is shown below. Fill in the most likely
genotypes of the indicated individuals in the pedigree. Note that a
dominant allele followed by an underscore (_) indicates that either
the dominant or the recessive allele may be present at the second
position. Drag one pink label (for condition A, autosomal
recessive) to each pink target. Drag one blue label (for condition
B, X-linked recessive) to each...

need help with pedigrees
You are a genetic counselor. The data: Henry has a double row of eyelashes, which h is a dominant trait. Both his maternal grandfather and his mother have double eyelashes. Their spouses are normal. Henry is married to Isabella and their first child, Polly, has normal eyelashes. The couple wants to know the chances of any child having a double row of eyelashes. Construct two blank pedigrees. Begin with the maternal grandparents and end with Polly...

PEDIGREES When a trait follows Mendelian inheritance it is often possible to figure out its dominance state by using a pedigree. Below are four pedigrees for four different traits. They are all autosomal traits (meaning they are not inherited on the X or Y chromosomes). For each trait, determine if it is dominant, recessive or unable to be determined. And explain each answer If it helps your explanation, you may label the symbols with letters Remember squares are males, circles...

A color-blind father and normal vision mother have three children. One daughter has normal vision; another daughter and son have red-green color-blindness. Draw the pedigree chart for this family, using the generally accepted symbols and including a legend, and indicate the genotypes of all...

For each pedigree below determine the most likely mode of
inheritance and label each individual with a genotype. If you know
they have a dominant phenotype, but don’t know the genotype, then
label them with both possibilities. Please use the alleles A and a
for autosomal modes of inheritance and XA, Xa and Ya for any types
of sex-linkage (note: an “a” is only on the Y if the trait is
Y-linked). Modes of inheritance are autosomal dominant, autosomal
recessive,...

NAME: 6. Red-green color deficiency is an X-linked recessive trait. A woman with normal color vision has a father who is color-deficient. The woman has a child with a man with normal color vision. Which phenotype is NOT expected as a possibility for that child? a) a color-deficient male b) a color deficient female c) a male with normal color vision d) a female with normal color vision 7.

Q5. You also want to determine the genotype of your parental pea plants based on the color of the plant (green is dominant to albino). One of your pea plants is green and the other is albino. What could you do to determine the genotype for color of each of your pea plants? 13 Q6. Based on the information you added to Table 8.2, explain why autosomal recessive traits can skip generations but autosomal dominant traits generally do not. /2...
