ANTH 101 Lecture Notes - Gregor Mendel, Homologous Chromosome, Dihybrid Cross
Document Summary
As mentioned in previous pages, the genetic information found in dna is essential in creating all the characteristics of an organism. This remains the case when passing genetic information to offspring, that can occur via a process called meiosis where four haploid cells are created from their diploid parent cell. For a species to survive, and genetic information to be preserved and passed on, reproduction must occur. This can be done by passing on the information found in the chromosomes via the gametes that are created in meiosis. Humans are diploid creatures, meaning that each of the chromosomes in our body are paired up with another. Haploid cells possess only one set of a chromosome. For example, a diploid human cell possesses 46 chromosomes and a gamete created by a human is haploid possesses 23 chromosomes. Tetraploid organisms possess more than 3 sets of a particular chromosome.
