Crossing Over (Noun)
Meaning
The interchange of sections between pairing homologous chromosomes during the prophase of meiosis.
Classification
Nouns denoting natural processes.
Examples
- Crossing over increases genetic variability by creating new combinations of alleles that can lead to adaptation and evolution.
- The process of crossing over is critical in meiosis, as it allows for the shuffling of genetic material and the creation of unique offspring.
- Crossing over can result in increased fitness and diversity in a population, thereby enhancing its ability to adapt to changing environments.
- During prophase I of meiosis, crossing over occurs between homologous chromosomes, leading to the exchange of genetic material.
- The frequency and location of crossing over events can be influenced by various factors, including the distance between genes and the degree of chromosomal synapsis.
