Black eyes are dominant to orange eyes, and green skin is dominant to white skin. sam, a mendalien with black eyes and green skin, has a parent with orange eyes and white skin. carole is a mendalien with orange eyes and white skin. if sam and carole were to mate, the predicted phenotypic ratio of their offspring would be

Sam, a mendalien with black eyes and green skin, has a parent with orange eyes and white skin. Sam has a dominant phenotype expressed but he has a parent with a recessive phenotype which means he has a heterozygote gene.

Carole is a mendalien with orange eyes and white skin. Since Carole express both recessive phenotypes she should be homozygote recessive.

The key to this problem is how Sam dominant gene will be inherited. Since there are two heterozygote genes, it will be 50% dominant gene inherited for each phenotype. Then the result should be: 
25% Dominant + Dominant =black eyes and green skin
25% Dominant + Recessive =black eyes and white skin
25% Recessive + Dominant  =orange eyes and green skin
25% Recessive + Recessive =orange eyes and white skin
