Document Summary

Genotype: the genetic make up of an organism, alleles contained. Homozygous: both alleles for a gene are identical. Used plants b/c you can control their production and they have shorter gestation pe production. Truebreeding: making sure plants were pure in one phenotype by mating them phenotype. Hypothesis: when 2 contrasting pea plants were mated, offspring would be irreversibl. What happened: round and wrinkled seed plants blended, first gen had only round but had one wrinkled seed plant. Test cross: test to find the genotype of a dominantly phenotype parent by crossing it w recessive plants and using the offspring ratio to discover the genotype. Law of segregation: when individual produces gametes, 2 copies of gene are separated so e. Law of independent assortment: alleles of different genes are assorted independently of ea formation. Believed genes were inherited independently but entire chromosomes with thousands single unit. In reality, linked genes on chromosomes and genes can be separated via recombinat.
