Brenna FerrellGenotype/PhenotypeIntroductionGenotype: combination of alleles inherited from your parents.Phenotype: the trait expressed by the alleles.Homozygous: identical alleles for a trait. Example: DD or ddHeterozygous: combination of different alleles. Example DdDominant allele (D): covers up the recessive alleleRecessive allele (d): is covered by the dominant alleleBoth DD and Dd will result in the expression of a trait. You only need one of the dominant allele to exhibit the dominant trait. A person who exhibits a dominant trait will probably not know his/her genotype for that trait. On the other hand, aperson who exhibits a recessive trait always knows what his/her genotype is because no dominant allele is present.Interesting: Trait Frequency in General Population: Tongue rolling: Can roll tongue – 70%Cannot roll tongue – 30 %Follow the directions indicated on the chart to determine if you are dominant or recessive for certain traits. Once this has been established, predict what your possible genotype(s) is/are. Fill in the chart and submit for credit.
