Variation Course Works Samples For Students

- Factors in phenotypic variations
Factors in phenotypic variation consist of: Variation in phenotype (Vp); Variation in phenotypes caused by genetic variation (Vg); Variation of phenotype caused by environment (Ve); Variation in phenotype caused by interaction of genotype and environment (Vgxe). In addition to the above factors, phenotypic variation is also influenced by effects of genotype on phenotypes.

- Additive genetic variation formula shows that Va is influenced by phenotypes (p), additive (a) and dominance (d). As population evolves, the values of p, a, and d change. Consequently, Va value also changes. Based on the narrow sense heritability formula, change in Va ...

Question 1

Quality can be defined as elusive in that different people interpret it differently. Few can define quality in measurable terms that can be operationalised.

- Transcendental quality

According to this approach, Quality is a natural factor that is recognizable worldwide as a mark of high standards free from any defects. Some people see it as one which cannot be given a definite definition since human beings can only learn through experience. Examples of this are;

“Where shopping is a pleasure” Supermarket; “We love to fly and it shows” Airline.

Meiosis and mitosis

Gene transfer occurs during cell division from mother cells to daughter cells. The DNA carries the genetic information transfer which it from one cell to another during cell division. Genes are located on the DNA strand that is contained in a chromosome. Mitosis and meiosis are the two types of cell division that occur during reproduction in various organisms. Mitosis involves the nucleus dividing into two identical daughter cells. Mitosis goes in hand with cytokinesis, which result in two separate daughter cells at the end of division. The process of mitosis takes place in four phases namely the prophase, metaphase, ...

Control charts are statistical tools that plot quality characteristics in order to measure whether a process is under statistical control. Their basic purpose of such charts is to control process variation. The characteristic measured by control charts is usually plotted on the vertical axis, while the sample is displayed on the horizontal axis. Control charts also illustrate the process mean as well as upper and lower control limits, which are drawn 3 standard deviations above and below the central line respectively.

These limits are used to make conclusions about the statistical stability of the process.
In case control charts ...

Introduction

Selection of materials is an important part of engineering design. Material selection is aimed at increasing the performance as well as the life of the engineering component and hence, very important for success of engineering component.

1.Jupiter was the first. Giant lies just beyond the frost line. As the frost line accumulated great amounts of water via evaporation from infalling icy material, it created a zone of lower pressure that increased the speed of orbiting dust particles and halted their motion toward the Sun. As a result , the frost line acted as a barrier whice lead material to accumulate. This excess material coalesced into a huge embryo of around 10 Earth masses, which then began to grow rapidly by swallowing hydrogen from the surrounding disc, reaching 150 Earth masses in only another 1000 years and finally topping out at ...

There are five principles of verbal communication and a further five for nonverbal communication. These principles are important for the sender and receiver to achieve effective communication and establish a shared understanding (Cheesebro, O’Connor & Rios, 2010).

The first principle of verbal communication is to recognize that all languages have value. There is no language that is better than the other in terms of logic, ability to convey thought or complexity.

The second principle is to understand that everyone speaks a dialect. A dialect is a regional variation of language. It includes unique pronunciation, vocabulary and grammar. Despite the differences in dialects, ...

Reliability and Validity

I. Reliability of a Test

The reliability of a test is defined as its degree of consistency, stability, accuracy and predictability hence the repeatability of its scores. Generally, it refers to the extent to which the ultimate results of a given test are consistent over time thereby presenting a degree of accuracy representative of the total population considered under the study. Reliability is quantified in terms of reliability coefficient. The reliability coefficient give insight on the significance of the scores (Waltz, Strickland, & Lenz, 2010). A high reliability coeffiecient implies that the findings are considerably plausible, while a low reliability coefficient implies that the ...
