Black Andalusian chickens result when two alleles for melanin production are inherited (MM). White-splashed chickens result from the inheritance of two copies of a different allele (mm). The heterozygous condition (Mm) results in their famous bluish color.

1. Armin and Annie are going to have a baby. Annie has dimples in her cheeks (a dominant trait), while Armin does not. You know that Annie's father has dimples in both cheeks, while her mother does not. Her mother must have the recessive trait. Annie's father has the dominant trait. but vou don't know if he is a homozygote or heterozygote. But you still know what Annie's genotype must be because Annie must have a recessive allele since that is all she could have inherited from her mother. Since Annie has a dimple you know she inherited a dominant allele from her father. What are the chances Armin and Annie's baby will have dimples? Determine the Phenotype and Genotype and its probability.
8. In complete dominance, what is true about a dominant phenotype? It is seen only in the absence of the recessive allele in the genotype It is seen only when there are two recessive alleles in the genotype O It is seen no matter what the genotype is It is seen as long as there is one dominance allele in the genotype
