Question

Part of the difficulty of the genetics unit is knowing what type of problem you are being asked to solve and then solving it correctly. The following problems are a mix of normal Mendelian inheritance, incomplete dominance, co-dominance, sex-linked, and dihybrid crosses. Complete each of the problems below. Show your work! It’s difficult for me to know where you are making your mistakes (and help you to correct them) if I cannot see how you completed the problem.

In seals, long whiskers (W) are dominant over short whiskers (w). What are the genotypic and phenotypic ratios for the offspring produced by mating a seal that is homozygous recessive with one that is heterozygous?

Genotypic Ratio:_______________________________

Phenotypic Ratio:_______________________________

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.
