Albinism is a genetic disorder caused by an autosomal recessive allele. The dominant allele results in the wildtype pigmentation. a) If an albino marries a homozygous person for the wildtype pigmentation allele, what would be the expected phenotype and genotype of their children? b) If an albino marries a person with wildtype pigmentation but that carries the albino allele, what would be the expected phenotypes and genotypes of their children? c) Two parents of wildtype pigmentation had an albino child....

Evaluating your phenotypes and genotypes and testing a genetic hypothesis in corn There are two activities in this write up. In the first, you will evaluate your phenotypes and genotypes and relate them to parental phenotypes and genotypes. In the second, you will test a hypothesis using a monohybrid cross in corn and carry out a Chi-squared analysis. For the write up, please copy and paste the remaining part of the Lab document into a new document, then fill in...
