Blending inheritance - Study guides, Class notes & Summaries

What is Molecular Biology?A hybrid discipline that combines elements of genetics and biochemistry. It is the study of gene structure and function at the molecular level (cloning methodology, RNA, DNA, how genes operate, nucleic acid chemistry). Can the earliest work on genes be considered as molecular biology or molecular genetics?no Was the molecular nature of genes known?no What is the early work on genes termed?transmission genetics, as it dealt with the transmission of traits from...

1. How did the Hopi culture contribute to the high incidence of albinism among members of the Hopi tribe? Solution: In the Hopi culture, albino individuals were considered special and awarded special status in the village. Hopi male albinos were not required to work the fields, thus avoiding extensive exposure to sunlight that could prove damaging or deadly. Albinism was considered a positive trait and not a negative physical condition, which allowed albinos to have more children, increas...

Allele - alternative form of a gene (one member of a pair) located at a specific position on a specific chromosome (a letter) Codominance - occurs when BOTH alleles of a gene are expressed in an individual (ex. Black + White = Black & White Speckled) Dihybrid cross - a two-trait cross (ex. color & shape) Dominant Allele - an allele that produces the same phenotype whether its paired allele is identical or different (capital letter) F1 Generation - first filial generation is the generation...

Artificial cross-fertilization - Answer- removing anthers from a flower and introducing pollen of the desired type with a small brush Pure-breeding strains - Answer- strains that consistently produce the same phenotype Took Mendel two years to prepare his P1 (Parental) generation - Answer- The original parents F1 (Filial) generation - Answer- offspring of the P generation Replicate crosses - Answer- repeat each cross several times Reciprocal crosses - Answer- The same genotypes...

CBE 235 Final.Lac Operon - correct answer -involved in heating lactose: inducible operon 1) The lactose repressor protein coded by Lacl bound to the operator tightly near the mRNA start site, blocking the ability of RNA poly to bind 2) Lactose introduced--> Lac repressor binds to lactose and changes conformation such that it can no longer bond to the operator 3) RNA poly can access the promoter and transcription goes 4) LacZ,LacY,LacA are transcribed Gregor Mendel Experiment - correct ...
