Someone help!!! Plz plz

You need to determine the sequence of a linear decapeptide. The following experiments have been performed:
1. Edman degradation generates 10 amino acids: Q, E, M, R, K, C, F, P, Y, A.
2. Cyanogen bromide (CNBr) cleavage gives two pentapeptides (5 aa’s).
3. Trypsin cleavage gives two tripeptides (AMR and QFK), and a tetrapeptide.
4. Chymotrypsin cleavage gives a dipeptide QF, a single amino acid, and a heptapeptide (7).
5. The C-terminal residue is identified as Cys using carboxypeptidase C, which removes amino acids from the C-terminal end of a polypeptide.
Give two possible sequences for the decapeptide, using aa three-letter codes.

A genetic trait is inherited via the Y chromosome such that for a father with the trait, his male offspring have a 25% chance of inheriting it but his female offspring cannot inherit it. Suppose that in a certain population, 40% of offspring are male and offspring genders are independent events. For a father with the trait who has two offspring, what is the probability that the older offspring has the trait and the younger offspring does not?

what are the various characters of living beings​

In rats, gene B produces black coat color if the genotype is B-, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D-, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. A third independently assorting gene involved in determination of coat color in rats is the C gene. At this locus, the genotype C- permits expression of pigment from genes B and D. The cc genotype, however, prevents expression of coat color and results in albino rats. For each of the following crosses, determine the expected phenotypes and their ratio in progeny:Part ABbDDCc x BbDdCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part BBBDdcc x BbddCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part CbbDDCc x BBddCcExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).Part DBbDdCC x BbDdCCExpress your answer as five numbers separated by colons. If there is no progeny of a particular phenotype, enter zero (black:brown:yellow:cream:albino).

The Siamese cat breed has a light colored body and dark colored head, tail, and feet, all of which are called points. The Burmese cat breed has a dark colored body and points that are almost the same color as the body. Crossing Siamese with Burmese can produce the Tonkinese cat breed, which has coat and point color that is intermediate to the Siamese and Burmese parents.

In all three breeds, a temperature sensitive enzyme is responsible for the dark coloration of the points. However, it is active only at the extremes of the body where it is coolest. Select the statements that are true regarding the evidence of incomplete dominance and incomplete penetrance in these breeds.

a. Intermediate coat color in Tonkinese demonstrates incomplete dominance.
b. Development of points in Tonkinese demonstrates incomplete penetrance.
c. Light coat color in Siamese demonstrates incomplete penetrance.
d. Darker color at the extremes of the body in Tonkinese demonstrates incomplete dominance.
