Yesterday we had some time to finish up the "classwork quiz" and then looked at the directed reading and quiz for Mendel's theory. Today we started with a set of daily questions that reviewed this concept of genotype and phenotype:
*If someone exhibits a dominant phenotype – what are the possible genotypes they
could be? Dominant/Dominant TT (Homozygous dominant) or Heterozygous (Dominant/Recessive Tt)
*If someone exhibits the recessive phenotype, what are the possible genotypes they
could be? ONLY homozygous recessive (two recessive alleles) tt
*True or False: Dominant traits are more common in a population. Very Very False - being Dominant ONLY means that if it is present THAT is what is expressed. NOT that it is more common or "better" for instance. Having 6 fingers is a dominant trait. I don't know many people with 6 fingers on each hand.
After that we reviewed some of the notes on genotype vs phenotype and begin to make predictions of genotypes based on phenotypes with the widow's peak trait. This will lead us into an activity where we will be taking an inventory of our own traits starting tomorrow!
