Epistasis (Greek: 'standing upon') occurs when one gene (the epistatic gene) masks or suppresses the phenotypic expression of another gene at a different (non-allelic) locus (the hypostatic gene). This is a form of gene-gene interaction (non-allelic interaction). Classic examples: coat colour genes in Labrador dogs; feather colour in chickens. Epistasis modifies expected Mendelian ratios (9:3:3:1) to produce ratios like 9:7, 12:3:1, 9:3:4, or 15:1.

Chemistry QUESTION #7174

Question 9067

In the context of the Bohr model of the atom, which of the following statements is true regarding the angular momentum of an electron in a hydrogen-like atom?

It is proportional to $\sqrt{n}$
It is an integral multiple of $\frac{h}{2\pi}$✔️
It is independent of the orbit number
It is proportional to $n^{2}$

Correct Answer Logic:

Bohr's second postulate states that the angular momentum ($L$) of an electron orbiting the nucleus is quantized and can only take values that are integral multiples of $\frac{h}{2\pi}$. Mathematically: $mvr = \frac{nh}{2\pi}$, where $n = 1, 2, 3...$

Question 9070

What is the maximum number of electrons that can be associated with quantum numbers $n=3$, $\ell=1$, and $m=-1$?

2✔️
10
6
4

Correct Answer Logic:

For $n=3, \ell=1$ (3p subshell), $m=-1$ specifies a single orbital (one of the three 3p orbitals). Each orbital holds a maximum of 2 electrons (with opposite spins, $s = +\frac{1}{2}$ and $s = -\frac{1}{2}$), by the Pauli exclusion principle.

Dairy Food Science and Technology QUESTION #5959

Question 9072

The 'string test' for mozzarella quality assesses:

$\text{pH}$ of the cheese brine
The stretching ability and fibrous texture of the pasta filata curd, indicating proper casein alignment (requires curd $\text{pH}\;5.1\text{–}5.3$ and temperature $55\text{–}65^{\circ}\text{C}$)✔️
Fat content by the length of the string formed
Moisture content by the weight of the string

Correct Answer Logic:

The string (pull/stretch) test evaluates whether mozzarella curd has been properly plasticized and stretched. Good mozzarella forms continuous elastic strings when pulled; poor plasticization at incorrect $\text{pH}$ or temperature results in breaking rather than stretching.

English Literature QUESTION #10699

Question 9073

Who was the principal contributor to the development of the linguistic (historical/comparative) period in language study?

Bartlett
Piaget
Hermann Paul✔️
Chomsky

Correct Answer Logic:

Hermann Paul (1846–1921) was a leading figure of the Neogrammarian school, which dominated 19th-century historical-comparative linguistics. His major work Principien der Sprachgeschichte (Principles of Language History, 1880) systematised the study of language change. Chomsky belongs to the generative/transformational period; Piaget to cognitive development; Bartlett to memory psychology.

Quantitative Reasoning QUESTION #8133

Question 9075

Only by ignoring years of mismanagement and inefficiency could investors believe that a new injection of capital would provide anything other than a _______ solution to the company's financial problems.
(Select the best word. Note: two words produce sentences alike in meaning — choose the most accurate.)

fleeting✔️
complete
premature
trivial

Correct Answer Logic:

The sentence implies that without fixing underlying problems, any cash injection would only work temporarily. Fleeting (lasting only a short time) is the best fit — a stopgap, not a real fix. 'Momentary' would also work (these two are the synonym pair in the original). 'Complete' is the opposite of what's implied. 'Premature' means too early, not temporary. 'Trivial' means insignificant, not temporary.

Research consistently shows that poor work performance is the result of:
