Document Summary
Presented the work to the natural history society of brno: 1865. Mendel"s work re-discovered independently by hugo de vries and carl correns in the context of their own experiments: 1900. Mendel s peas were highly in-bred because lower structure promoted self- ferilizaion: therefore bred true (ex. when two tall plants were crossed, they only produced tall progeny) Mendel s experiments were designed so that he could study one trait at a time. A monohybrid cross (a single trait is followed) In a geneic cross, the parents are referred to as the parental (p) generaion. Their ofspring represent the irst ilial (f1) generaion. Each trait controlled factor that two forms: o o. Dominant forms traits behaved the appeared to be by a heritable came in one of. Recessive heritable factor = and recessive called alleles. Heterozygous the two alleles are diferent. Locus ixed posiion on a chromosome (plural loci) In a heterozygote, one allele may conceal the presence of another.
