Organizational behavior is a field of study that investigates the impact that individuals, groups, and structures have on behavior within organizations, for the purpose of applying such knowledge toward improving an organization's effectiveness. Organizational behavior is an interdisciplinary field that includes sociology, psychology, communication, and management. It is a broad field that examines various aspects of human behavior in organizations and the ways in which these behaviors can be improved or modified to enhance organizational effectiveness.

One key aspect of organizational behavior is the study of leadership. Leadership refers to the ability of an individual or group to influence and guide others towards the achievement of a common goal. There are many different leadership styles, including autocratic, democratic, and laissez-faire, each with its own unique set of characteristics and effects on organizational behavior.

Another important aspect of organizational behavior is motivation. Motivation refers to the forces that drive an individual to behave in a certain way. It can be intrinsic, such as a personal desire to achieve a goal, or extrinsic, such as a reward or punishment. Motivation is a key factor in determining an individual's level of engagement and performance in an organization.

Group dynamics is another important aspect of organizational behavior. Group dynamics refers to the way in which individuals in a group interact with one another and the impact that these interactions have on the group's behavior. Group dynamics can be influenced by a variety of factors, including group size, diversity, and communication patterns.

Organizational culture is another important concept in organizational behavior. Culture refers to the shared values, beliefs, and behaviors that are characteristic of an organization. It is the unique personality of an organization, and it can have a significant impact on the behavior of its members.

There are many other topics that fall under the umbrella of organizational behavior, including communication, decision-making, conflict resolution, and power and politics. Understanding and studying these topics can help organizations to better understand and improve the behavior of their employees, and ultimately lead to increased effectiveness and productivity.

In conclusion, organizational behavior is a multifaceted field that investigates the various factors that impact the behavior of individuals and groups within organizations. By understanding and studying these factors, organizations can improve the behavior of their employees and increase their overall effectiveness and productivity.

The pea plant was perfect organism for Mendel to observe because it reproduces quickly, and in large numbers, and is fairly easy to manipulate. Take the photos of your experiments in each activity as directed below. The format and requirements of the lab report are in Lab Report writing aid. Smooth shapes seem hard and starchy. For the second generation I was able to discover that offspring would show a ratio of 9:3:3:1. The Title page information should be absolute centered on the page. RESULTS: MONOHYBRID CROSS First generation Phenotype: smooth x shrunken Genotype: SS x ss S S s Ss Ss DIHYBRID CROSS First generation Phenotype: purple, smooth x yellow, smooth Genotype: YYSS x yySS Gametes: All YS x all yS YS YS YS YS yS YySs YySs YySs YySs yS YySs YySs YySs YySs yS YySs YySs YySs YySs yS YySs YySs YySs YySs All of the F1 generation would all be heterozygous for both characteristics.

All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying APA citations. The combination of the two alleles is known as a gene. This also mean there is 50 % chance that their offspring would be a carrier, since half of those born are heterozygous Cc. Do NOT make any statements about the data collected. Read the previous paragraph to answer this question! The hypothesis we concluded for the simulations is that the predators on the light towel bench, which represents one of our three environments, would be more fit than the predator in the other two environments.

Make a cross between a true breeding tall pea plant and a true breeding short pea plant. Once we have about 6 virgin wild type females in the vial, we isolated 6 ebony males and placed them in to the vial. The F1 from a cross of two pure lines contains one allele for the dominant phenotype and one for the recessive phenotype. If the pigmentation gene is turned off long enough by transposon, the grain will be completely unpigmented. The resulting generation is the F 2 generation hybrids of hybrids , and the results awaiting him were another surprise to M endel.

You should NEVER DISCUSS what the data MEAN in this section. Females are sexually mature after 8 hours and can then begin to mate and lay eggs. The unit will be placed in the spray booth. Based on the Punnett square above, what is the percentage of offspring that are predicted to have purple stems and yellow-green leaves? For this experiment specifically, Drosophila were a great organism to use, as we wanted to look at Mendelian Inheritance, so phenotypes of parents and their offspring, and we only had a brief time span to observe this. If I take all ACCEPTED data, crosses 1,2,3,4 and 6, the chi square value is 0. This law states that for every gene there are two alleles that segregate during meiosis Griffiths et al.

Materials and Methods For this experiment, I was given a container of Drosophila marked with yellow tape and the number three. References are never bulleted or numbered. A list of the genotypes in each of the parental P1 , F1 and F2 generations. To test the theory of inheritance, scientist Thomas Hunt Morgan used the fruit fly. . I used the paint brush to aid me in moving the flies to where they needed to be. First thing we did was set up additional stocks of both types of drosophila.

Despite differences between my data and the compiled data, both chi-squared analyses both failed to reject the null hypothesis. After that, I was able to perform Chi-square test. All flies that emerge once the F1 parents have been removed are now F2 generation. Inevitably, the study of inheritance always leads to additional questions. Again, after 7 to 10 days once larvae appear the parents are removed. Basic Format for List of references at the End of the Lab Report : APA style dictates that authors are listed last name first followed by first name initials; publication year goes between parentheses, followed by a period.

Also under the first level 1 heading, present a box and line process flow diagram PFD drawing of the selected scenario. It is also beneficial that the flies have a short lifespan. The first is the law of segregation. First, I used the fly nap to get the flies to stay still while I sorted them. Materials and Methodology This section is used to describe HOW the experiment was performed.

All tables and figures should be described in NARRATIVE format. Examples might include a water treatment facility that utilizes liquefied chlorine gas, a coal fired power plant that utilizes liquefied chlorine gas for water treatment, a food processing plant with a large ammonia refrigeration system, a fertilizer manufacturing or storage facility, a chemical manufacturing facility, etc. We wanted to determine whether the mutant alleles were dominant or recessive, whether they were X-linked or autosomal, and whether the two genes are linked. The Punnet square protocol A cross of FF purple-flowered peas with ff white-flowered peas is shown as an example. With this data, a chi-square analysis was conducted.
