Study Notes
NCEA Biology Standard 91606
- Focuses on understanding the principles of genetics, specifically relating to the transmission and expression of traits.
- Assesses students' ability to analyze and interpret genetic data and processes.
Studying Allelic Frequency
- The most effective method for studying allelic frequency in a population is by conducting population sampling and genetic analysis.
- Techniques like gel electrophoresis or DNA sequencing provide insights into variations in allele frequency.
Carrying Capacity in Ecological Interactions
- Carrying capacity refers to the maximum population size of a species that an environment can sustain indefinitely without degrading that environment.
- It is influenced by resource availability, habitat space, and the impact of competing species.
Inheritance Patterns
- Traits controlled by multiple genes exemplify polygenic inheritance.
- This results in a wide range of phenotypic expressions, often observed in characteristics like height, skin color, and intelligence.
Natural Selection Process
- Natural selection is defined as the process where organisms with advantageous traits survive and reproduce more successfully than those without these traits.
- It leads to the gradual adaptation of populations to their environments over generations, contributing to evolution.
