Magical ability is a dominant trait controlled by two loci. To be able to perform magic, a person would need to carry at least o

n copy of the dominant allele on each of the two loci. Hermione Granger has magical ability but neither one of her parents does. Which of the following are possible genotypes for Hermione Granger’s parents?
a. AAbb x Abb
b. aaBb x AAbb
c. aaBb x aaBB
d. AaBb x AaBb
e. None of the above

Answer:

b. aaBb x AAbb

Explanation:

According to the information in this question, the trait for magic ability is controlled by two genes, each comprising of two alleles i.e. A,a and B,b. However, to be able to perform magic, a person would need to carry at least one copy of the dominant allele (A and B) on each of the two loci.

Hermione Granger has magical ability but neither one of her parents does. This means that although Hermione can perform magic, none of her parents can. Genetically, it means that Hermione posseses at least one copy of the dominant allele on each of the two loci i.e. her genotype is A_B_.

This is only possible in Hermione if her parents transferred a dominant allele at each loci to her. This means that the possible genotypes for Hermione Granger’s parents are aaBb (no magical ability) x AAbb (no magical ability). See the punnet square attached where the probability of producing offsprings with magical ability is 1/2 or 50%.

Dna testing was commonly used in forensic science beginning in the 1920s. True or false?
Molodets [167]

Answer:

False.

Explanation:

I am almost entirely sure that DNA testing had not been discovered at this time, but regardless of whether that is true, the very first criminal case that DNA testing was used in occurred in 1985. So no, it was not used commonly in the 20's.

What will happen when the 14 grams of protein in the Greek yogurt is eaten by person
elena-s [515]

Answer:

it gives energy.

Explanation:

If a person consumes 14 grams of protein present in the Greek yogurt, it gives high amount of energy because protein is a macromolecule which is needed by the human in large amount in order to maintain health of the body. This protein is broken down by a number of enzymes and converted into amino acids which is used in the growth of the body, formation and repairing of muscles.

When is the generation of an action potential impossible no matter the strength of the stimulus?
ANTONII [103]
The right answer is <span>Refractory period.

At the moment when the action potential is emitted, the fiber being depolarized, it is impossible to depolarize it again. It is, therefore, necessary to wait until the membrane potential returns to a value below the critical threshold in order to be able to excite it again. We are thus led to distinguish two periods that characterize its excitability.
An absolute refractory period: during which any stimulation, even supraliminal, is ineffective since the fiber is already depolarized.
A relative refractory period: during which a second action potential can be omitted provided that the depolarization produced by the excitation reaches the critical threshold, which implies that it is more important since the value of the resting potential has not been restored yet.</span>
