The parts of the microscope through which you view the specimen are called the eyepieces. The eyepieces are located at the top of the microscope and are usually magnifying lenses that magnify the image of the specimen.

They are the first optical components that the user looks through and typically magnify the image by 10x.

The eyepieces are usually located near the focus of the microscope and work in conjunction with the objective lens, which is located at the bottom of the microscope, to magnify the specimen. The objective lens is typically focused onto the specimen, and the image is magnified as it passes through the eyepieces.

The combination of the objective lens and the eyepieces determines the overall magnification of the microscope, with higher magnification achievable by using higher power objective lenses and eyepieces.

Recessive features often only manifest in the phenotype when two of these (recessive) alleles are present, and carriers (heterozygous people) make up the majority of the population.

An individual inherits one of each of the two alleles for each gene from each parent. When a trait is recessive, both of the gene's (recessive) alleles must be present in order for the trait to be present. An allele has no effect if there is only one copy of it.

Dominant describes the association between two genetic variations. An individual inherits one of each of the two alleles for each gene from each parent. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be expressed.

It is true that the overuse or improper conditioning of the leg muscles is the main cause of shin splints.

Shin splints, sometimes referred to as medial tibial stress syndrome, are a frequent overuse condition that mostly affects the front and inside of the shin bone in the lower leg (tibia).

The muscles, tendons, and bones in the lower leg are repeatedly stressed and strained in this condition, frequently as a result of overuse or poor training.

Running or leaping on hard surfaces, stepping up the intensity or duration of exercise too rapidly, wearing unsuitable or worn-out footwear, and having weak or imbalanced leg muscles are all common causes of shin splints. Shin splints cause pain along the inner rim of the shin bone, which can be anything from a faint ache to a searing pain.

When one allele (variant) of a gene is present on one copy of a chromosome, and its effects of the other allele (variant) of the same gene on the other copies of the chromosome can be suppressed or overridden. This is known as dominance. Recessive describes the second form whereas the dominant characterizes the first. The fundamental cause of the phenomenon of two unique variants of the same genes on each chromosome is a gene mutation, either new (de novo) or inherited. Autosomal dominant and autosomal recessive are names which is used to describe traits of gene variations on non-sex chromosomes (autosomes), whereas X-linked dominant, X-linked recessive, and Y-linked are the terms which are used to describe traits of gene variants on sex chromosomes (allosomes).

When a black is mated to a brown mouse, all of the progeny are black. This tells us that the genotypes of the parents are homozygous each.

The cross between a black mouse and a brown mouse can be explained with the help of the Mendelian monohybrid cross. Monohybrid cross is used to illustrate the inheritance of only single character from the parents to the offsprings. Here, the character inherited is the color of the mouse. If the F1 progeny produced after the cross of the parents is expressive of one of their parents, this means that the character expressed is dominant over the other. Hence, black color is dominant over brown color. The parents, therefore, were homozygous dominant, say BB for black, and homozygous recessive, say bb for brown.
