Question
Describe a specific example of a cross between two parents, each homozygous for different traits, which would result in a phenotype that is distinct from either parental phenotype.
1. Indicate the genotype and phenotype of each parent and the offspring.
2. Indicate the inheritance pattern of the character described.
Rules:
1. You may use imaginary organisms. Crosses involving dragons, hobbits, and unicorns are allowed.
2. The distinct offspring phenotype may not be a result of mutations.
3. Describe a cross that is not described in your textbook.
Explanation / Answer
Dominant alleles appear in a phenotype whenever they are present; recessive alleles contribute to the phenotype only if no dominant alleles are present. An individual is homozygous for a gene if both alleles are identical; in a heterozygous individual, the two alleles for a gene are different. An organism
