In humans, height, skin color, hair color, and eye color are examples of polygenic traits.
A polygene is a member of a collection of non-epistatic genes that interact additively to steer a phenotypic trait, consequently contributing to more than one-gene inheritance, a sort of non-Mendelian inheritance, in preference to unmarried-gene inheritance, which is the core belief of Mendelian inheritance.
A polygenic trait is a feature, which includes height or skin coloration, that is encouraged by way of or extra genes. because a couple of genes are concerned, polygenic developments do not comply with the styles of Mendelian inheritance. Many polygenic traits are also stimulated by means of the environment and are called multifactorial.
Most inherited trends in animals are polygenic. a few examples are: conformation, kind, size, sturdiness, disorder resistance, temperament, velocity, milk and egg production, growth fee, maturation and sexual adulthood rate, and numerous inherited diseases.

Answer: Volume of the gas at STP is 22.53 L.
Explanation:
Given : Volume = 125 mL (as 1 mL = 0.001 L) = 0.125 L
Temperature = 
Pressure = 
According to the ideal gas equation, the volume of given nitrogen gas is calculated as follows.
PV = nRT
where,
P = pressure
V = volume
n = number of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
Hence, volume of the gas at STP is 22.53 L.
<u>Ionic Bond</u> is formed when the electronegativity difference is 0.4 > 2.0. Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.
Explanation:
Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.
An electronegativity of an atom is affected by
- The atomic number of the atom
- Secondly by the distance at which the valence electron are residing from the nucleus
1. In case the electronegativity difference (which is denoted by ΔEN) is less than 0.5 then the bond formed is known as N<u>onpolar covalent.
</u>
2. In case the ΔEN is in between 0.5 and 1.6, the bond formed is referred to as the<u> Polar covalent
</u>
3. In case the ΔEN is more /greater than 2.0, then the bond formed is referred to as<u> Ionic Bond</u>
<u>2 Examples of Ionic bonds</u>
- The formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom is an example of Ionic bond formation.
- Another example is the formation of NaCl from sodium (Na),which is a metal, and chloride (Cl), which is a nonmetal
