Natural Selection the process that results in adaptation of a population to the biotic and abiotic environments. Polygenic controlled by more than one pair of alleles located at different gene loci Directional Selection occurs when an extreme phenotype is favored and the distribution curve shifts in that direction. Example: resistance to antibiotics and pesticides Stabilizing Selection Occurs when an intermediate phenotype is favored. Individuals near the average are fav...

CHAPTER CONCEPTS ■ ■ The failure of chromosomes to properly separate during meiosis results in variation in the chromosome content of gametes and subsequently in offspring arising from such gametes. ■ ■ Plants often tolerate an abnormal genetic content, but, as a result, they often manifest unique phenotypes. Such genetic variation has been an important factor in the evolution of plants. ■ ■ In animals, genetic information is in a delicate equilibrium whereby the gain or loss of a ch...

GENETIC DIVERSITY AND MEIOSIS I - Introduction to genetics - Mendel rules - Meiosis We are talking about the change of generation and how genetic elements are behaving when they move from one generation to the next. We can think about this how our chromosomes as carries of genetic material and are moving from one generation to ne next, we have somatic cells, generative cells, we are changing between different ploidies and any polyploid organism would have the genetic set prior to the fe...
