    Using a Punnet Square to determine phenotype and genotype

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    I need to be able to list the work and list the expected phenotypic ratios for the following crosses:

    A. If a red cow is bred with a white bull, all offspring are roan, which have red and white hairs intermixed on the hide. I know this is an example of co-dominance, but what are the results of roan x roan?

    B. If solid x spotted = all solid, what will two heterozygous solids produce?

    C. heterozygous solid x spotted =

    D. AaBb x Aabb=

    E. AaBb x aabb=

    Solution Summary

    I use punnet squares to answer the following questions after defining allele, genotype, phenotype, cross, heterozygous, and homozygous.
    A. If a red cow is bred with a white bull, all offspring are roan, which have red and white hairs intermixed on the hide. I know this is an example of co-dominance, but what are the results of roan x roan?

    B. If solid x spotted = all solid, what will two heterozygous solids produce?

    C. heterozygous solid x spotted =

    D. AaBb x Aabb=

    E. AaBb x aabb=
