''A polygenic trait that follows non-Mendelian inheritance patterns'', is the statement best describes human eye color.
What is meant by non Mendelian inheritance?Any pattern in which characteristics do not segregate in line with Mendel's rules is referred to as non-Mendelian inheritance. These principles describe how qualities connected to a single gene on nuclear chromosomes are passed down across the generations. Each parent contributes one of the two potential alleles for a characteristic in the Mendelian system of inheritance. The distribution of phenotypes anticipated for a population of children may be calculated using Mendel's laws if the genotypes of both parents in a genetic cross are known. The proportions of phenotypes observed in the progeny occasionally do not match the values expected.Many diseases that affect the processes are impacted by non-Mendelian inheritance.Learn more about non Mendelian inheritance refer to :

Which statement is true regarding action potentials?
a. The generation or creation of an action potential does not depend on the strength of the stimulus a neuron receives.
b. Action potentials travel slower in myelinated axons.
c. An action potential once started, cannot be stopped or negated.
An action potential once started, cannot be stopped or negated
The action potential is initiated by a stimulus beyond a certain intensity, known as the threshold stimulus. Beyond the threshold stimulus, the strength of the stimulus does not affect the amplitude of the impulse.
What is action potential ?A neuron transfers information away from the cell body through an axon, resulting in an action potential. For the action potential, neuroscientists sometimes use the terms "spike" or "impulse." A depolarizing current produces the action potential, which is a surge of electrical activity.
Action potentials, nerve impulses, or occasionally just spikes are terms used to describe these spike-like events. The primary events used by nerve cells to convey information from one location to another are action potentials.

A biological catalyst is an enzyme. Reactions' activation energies are reduced by catalysts. The rate of a reaction increases with decreasing activation energy. Enzymes accelerate processes by reducing activation energy.
The bonds holding together the atoms in molecules are ruptured, altered, and repaired during a chemical reaction, recombining the atoms to form new molecules. By lowering the activation energy, the energy hurdle that must be cleared for a chemical reaction to take place, catalysts improve the efficiency of this process. As a result, catalysts facilitate the formation of chemical bonds between atoms to create novel combinations and new compounds. Chemical reactions are accelerated and become more energy-efficient when catalysts are used. Additionally, catalysts possess a crucial quality known as selectivity that allows them to control an unwanted products.

what is the role of the sodium potassium pump in establishing and maintianing resting membrane potential
The sodium-potassium pump continually removes three sodium ions from the cell for every two potassium ions it introduces. Thus, it preserves the significant potassium ion gradient across the membrane, which served as the foundation for the resting membrane potential.
What is the role of sodium-potassium pump?
The sodium-potassium pump is a protein that has been found in many cells and is responsible for keeping the internal concentration of sodium ions [Na+] lower than that of the surrounding medium (blood, body fluid, or water) and the internal concentration of potassium ions [K+] higher than that of the surrounding medium (blood, body fluid, or water). The adenosine-triphosphatase (ATPase)-active pump moves across the cell membrane and is triggered by both internal [Na+] and external [K+].
This enzyme pumps K+ inward and Na+ outward using metabolic energy. The steady state differential in Na+ and K+ concentrations maintained by the pump is essential for maintaining the resting potential of cells and associated bioelectric phenomena like the action potential. There have also been discovered additional ion pumps that transfer various ions.

suppose you identify a new gene in mice. one of its alleles specifies white fur, another specifies brown. you want to see if these alleles are inherited in a mendelian pattern, or with incomplete dominance. what crosses would give you the answer?
We can make three crosses. first, assuming that white is dominant, Assuming the brown-furred to be dominant, and Incomplete dominance to see if these alleles are inherited in a mendelian pattern,
The geneticists assign the alphabet at random if the alleles follow a non-Mendelian inheritance pattern. We select a true breeding strain of brown-furred mice and a true breeding strain of white-furred mice, both of which consistently produce heterozygous offspring; and the dominant allele is what causes the heterozygous phenotype. It is heterozygous for the F1 generation. Additionally, there must not be a link between the genes because mixing alleles prevent crossing over. A monohybrid crossing between a true-breeding brown-furred strain Mice and a true-breeding white-furred strain mouse is carried out assuming that the gene is only present in one locus.
Cross 1
assuming that white is dominant.
WW × ww
W W
w Ww Ww
w Ww Ww
In keeping with the Mendelian inheritance pattern, all of the F1 offspring are white. The F2 generation's ratio would be 3:1, with three white and one brown individual. This indicates that Browns is outnumbered by white
Cross: 2
Assuming the brown-furred to be dominant:
BB×bb
B B
b Bb Bb
b Bb Bb
All the posterity created in the F1 age is earthy colored following a Mendelian example of legacy. The F2 generation's ratio would be 3:1, with three brown and one white individual. This indicates that white is outnumbered by brown.

In the F1 generation, crossing over WW (white) and WW (brown) results in a tan color given by WW. In the F2 generation, this genotype exhibits a genotype ratio of 1:2:1 when self-crossed in the F1 generation. We discover that the obtained ratio is one white: 2 tan: 1 brown.
