What can you say about this plant? If the genotype is Rr, the phenotype will be red-flowered. Which observation led Mendel to the idea that traits were controlled by more than a single factor? A trait that was not seen in the first generation may later reappear in the second generation. The two different X in Y individuals plays ...

Gene vs Allele - Gene: A section of DNA that controls a certain trait. Example: Eye color. Allele: A specific variation of a gene. Example: Having blue eyes. Dominant vs Recessive - Dominant: Determines the expression of a trait (visually). Example: Brown eyes, dark hair. Recessive: Much less likely to determine the expression of a trait. Example: Blue eyes, blonde hair. Homozygous vs Heterozygous - Homozygous: A homozygous trait is when two of the same kind of alleles combine...

The term "n" refers to the size of a population, that is, the number of individuals in that population. In general, in a sample of n individuals, the frequency of an allele is: - Answer-the number of occurrences of the allele divided by twice the number of individuals in the sample (2n) If a population is not in Hardy-Weinberg equilibrium, we can conclude that: - Answer-evolution has occurred because one of the assumptions of the Hardy-Weinberg equilibrium has been violated The goldenrod ...

Learning Objectives:  Estimate the sex, stature, and age of death of an individual based on skeletal remains.  Identify and interpret the skeletal manifestation of some pathologies.  Critically evaluate the notion that there are different biological human races. Purpose: To become familiar with the methods employed by forensic anthropologists to create biological profiles of skeletal remains. Forensic anthropologists apply their knowledge of biological anthropology to modern medi...
