Document Summary

Darwin could not explain heredity so he adopted the ancient theory of. Pangenesis : everyone has some particles in them, the parents" particles merge and form a mixture in the children which explains the similarities and differences ( you have your mother"s eyes more eye particles from mother) Today we know that there are co-dominant traits. The idea that you get one trait from each parent is called the principle of. The recessive particle that they referred to is now known as the homozygous gene and the dominant particle is the heterozygous gene . Each different variant came to be known as an allele. It was eventually suspected by biologists that the genes are within the chromosomes saw that they occurred in pairs. Mitosis is the cells making copies of themselves reproduces all the pairs of chromosomes. A lot of hereditary traits have a lot of alleles polygenetic trait . One single gene can affect a lot of traits (pleiotropy)
