Biology Review of Genetic Behavior 150 150 Deborah

Biology Review of Genetic Behavior

Overview:  What Is Genetic Behavior? Morgan’s discovery of gender-linked traits was further evidence that genes were located on chromosomes.  However, other research indicated that the behavior of genes during meiosis was sometimes more complex than with gender-linked traits.  With the development of more powerful techniques of observation, specific genes could sometimes be located. What Is…

Biology Review of Chromosome Theory 150 150 Deborah

Biology Review of Chromosome Theory

Overview:  What Is the Chromosome Theory? The results of Mendel’s experiments on cross-breeding pea plants led to principles of heredity, but he wasn’t able to observe either chromosomes or genes in cells.  Microscopes in his time weren’t strong enough to detect those features.  In the late 1800’s and early 1900’s, scientists observed the processes of…

A Statistics Review of Confidence Intervals

Overview:  What Is a Confidence Interval? Unless the population is small enough to determine each member, researchers cannot know the exact value of the population mean.  However, using statistical techniques, it can be predicted that the mean falls within a certain range, called the confidence interval.  Using properties of sample size, standard deviation, and probability…
