Document Summary

Meiosis can result in 8. 4 million unique sets of dna excludes crossing over, within one person, not including complexity of sexual replication. Birth defects: genetic abnormalities, toxic substances, or viruses alter a speci c structure during a critical period, most birth defects occur during embryonic period, more sever than those that arise during the fetal period. Gregor mendel: austrian monk living in czech republic, grew and crossbred pea plants, other brain malformations, did so during period when darwin released the origin of. If trait is controlled by single locus and organism is diploid, then true breeding lines will be homozygous: no detectable variation for trait. Both copies are the same: breeding two homozygous individuals with di erent phenotypes results in heterozygous o spring, called monohybrid cross two di erent alleles - hybrid, one trait - mono. Punnet square represents how genes in gametes join if they are on di erent chromosomes.
