*If someone exhibits a dominant phenotype – what are the possible genotypes they could be? Homozygous Dominant (TT) or Heterozygous (Tt) - Remember - a recessive allele can be present but is not expressed when a dominant allele is paired with it.
*If someone exhibits the recessive phenotype, what are the possible genotypes they could be? Homozygous Recessive (tt) - there is only ONE possible outcome to this. The ONLY way a recessive phenotype is expressed is if there are ONLY recessive alleles for that trait.
*True or False: Dominant traits are more common in a population. VERY VERY FALSE!!! Dominant only means that it is expressed if present- NOT that it is more common OR that it is "better" (For instance - the allele for having 6 fingers is dominant over having 5 fingers......)
After the daily questions we continued through notes focusing on predicting genotypes based on phenotypes. One trait we looked at was the presence or absence of a widows peak..
