Diagnostic Misconceptions - Dihybrid Inheritance

Test yourself on Diagnostic Misconceptions - Dihybrid Inheritance

• What would the gametes be if there are two heterozygous parents with alleles for Long ears dominant over short (L and l) and Black fur dominant over white (B and b)?

• What are the phenotypic ratios for a dihybrid cross of heterozygous parents?

• What would be the potential offspring of a cross between two parents? One heterozygous and one homozygous recessive for both genes. Alleles are for Long ears dominant over short (L and l) and Black fur dominant over white (B and b).

• Which of the following is the gamete of a homozygous dominant parent?
