Twins have a very high correlation of loops‚ whorls and ridges. But the details (for example‚ where skin ridges meet‚ divide into branches‚ or end) differ between twins. Twins share the same genetic makeup (DNA) because they are formed from a single zygote. However‚ fingerprints are not an entirely genetic characteristic. They are determined by the interaction of genes in the developmental environment of the womb. Fingerprint patterns are set between the 13th and 19th weeks of development in the womb

from the woman’s ovaries and letting sperm fertilise them in a fluid medium in a laboratory. When a woman’s natural cycle is monitored to collect a naturally selected ovum (egg) for fertilisation‚ it is known as natural cycle IVF. The fertilised egg (zygote) is then transferred to the patient’suterus with the intention of establishing a successful pregnancy. In the video we saw a couple struggling to save the life of their only daughter with hopes of the mother conceiving another child to be a viable

INTRODUCTION TO SCIENTIFIC TERMINOLOGY The purpose of this document is to introduce root words and their definitions. These words play a vital role in Biology because many scientific terms are based on these words. Because these root words are Greek or Latin in origin‚ their meanings have remained consistent throughout time. By becoming familiar with root words and their definitions you can determine general meanings of many terms by simply applying these root word definitions. For example‚ the

According to Iris Young‚ the author of the chapter Five Faces of Oppression‚ the word oppression has come to represent communities and individuals that are being discriminated by the way society is structured‚ rather than a single leader oppression.

Group selection describes natural selection operating between groups of organisms‚ rather than between individuals. This would produce adaptations that benefit the group‚ rather than the individual. Darwin’s theory of evolution was based upon individual selection‚ and he rejected the idea of group selection. Artificial selection is the selective breeding carried out by humans to alter a population. It is a procedure often used in agriculture: artificial selection has been used to alter the number

· Taxonomy ○ Science of classification ○ Provides an orderly basis for the naming of organisms and for placing organisms into a category (taxon) ○ Makes use of and makes sense of the fundamental concepts of unity and diversity among living things ○ Basic principle is that members of higher-levels groups share fewer characteristics than those in lower-level groups * Escherichia coli - rod shape and have a Gram-negative cell wall * Even members of the same species display variations

Chapter 12 Cyclins and cyclin-dependent kinases are regulatory proteins that assist in the cell cycle. Particular protein kinases give the go-ahead signals at G1 and G2 checkpoints. These protein kinases are present at a constant concentration in the cell but are inactive unless in the presence of cyclin‚ these are cyclin dependent kinases. The activity of a cdk rises and falls with the concentration of cyclin. Cyclin levels rise during the S and G2 phases then fall abruptly in the M phase

Chapter 10 Foundations of Genetics Lecture Notes 1 Foundations of Genetics Mendel and the Garden pea The father of modern Genetics is Gregor Mendel. Gregor Mendel (1822-1884) was an Austrian monk who lived in a monastery where the experiments with the garden pea were performed. Mendel’s work with the garden pea was the fundamental study which unveiled the laws that govern genetics and heredity. Mendel was the first to use the scientific method in a very systematic and analysed his results
