What are 4 polygenic traits?.

Chemistry
1 answer:
Veseljchak [2.6K]1 year ago
6 0

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.

What are quantum numbers?

  • Quantum numbers are used to describe where around a nucleus a particular electron can be found.
  • In any given atom, each electron can be described by four quantum numbers.
  • These are n,l,m1,ms
  • The values that each number can be are based on a set of rules.

What is a magnetic quantum number ?

  • It describes the orientation of the orbitals.
  • It is represented as ml.
  • The value of this quantum number ranges from (-l to +l).

How many grams of K2CO3 are needed to prepare a 400.0 mL of a 4.25M solution?
Basile [38]

Answer:

235 g

Explanation:

From the question;

  • Volume is 400.0 mL
  • Molarity of a solution is 4.25 M

We need to determine the mass of the solute K₂CO₃,

we know that;

Molarity = Number of moles ÷ Volume

Therefore;

First we determine the number of moles of the solute;

Moles = Molarity × volume

Moles of  K₂CO₃ = 4.25 M × 0.4 L

                           = 1.7 moles

Secondly, we determine the mass of  K₂CO₃,

We know that;

Mass = Moles × Molar mass

Molar mass of  K₂CO₃, is 138.205 g/mol

Therefore;

Mass = 1.7 moles × 138.205 g/mol

         = 234.9485 g  

         = 235 g

Thus, the mass of  K₂CO₃ needed is 235 g

Definition for starch in science ?
Akimi4 [234]

Answer:

  1. Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. or
  2. Starch is a long-chain polymer of glucose molecules joined together. or
  3. A starch is a complex polysaccharide made up of a large number of glucose units joined together by glycosidic bonds.

Explanation:

starch, a white, granular, organic chemical that is produced by all green plants. Starch is a soft, white, tasteless powder that is insoluble in cold water, alcohol, or other solvents.

Starch is amongst the most abundant plant products and is a mixture of two polymers, amylose and amylopectin. During food processing starch is transformed by hydrothermal treatments. ... The structure of starch is also influenced by specific and non-specific interactions with other food constituents and ingredients.
