Predicted Phenotypic Ratio of Offspring from Sam and Carole Mating

Understanding Mendelian Genetics with Black Eyes and Green Skin

In Mendelian genetics, the dominant and recessive traits of parents determine the possible outcomes of their offspring. In this scenario, black eyes are dominant to orange eyes, and green skin is dominant to white skin. Let's look at an example involving two MendAliens named Sam and Carole.

The Parental Traits

Sam, a MendAlien, has black eyes and green skin. One of Sam's parents has orange eyes and white skin. Carole, the other MendAlien, possesses orange eyes and white skin.

Predicting the Offspring's Phenotypic Ratio

Based on the traits of Sam and Carole, we can predict the phenotypic ratio of their potential offspring. Since Sam carries the dominant traits of black eyes and green skin, these traits will be passed on to the next generation. Similarly, Carole's orange eyes and white skin will also be considered in the genetic combination.

The Predicted Phenotypic Ratio

Following the Mendelian genetics principles, if Sam and Carole were to mate, the predicted phenotypic ratio of their offspring would be:

1 black eyes, green skin : 1 black eyes, white skin : 1 orange eyes, green skin : 1 orange eyes, white skin

This ratio indicates that each trait combination has an equal chance of being expressed in the offspring. This simple Mendelian calculation helps us understand the inheritance patterns of traits in living organisms.

What is the predicted phenotypic ratio of the offspring if Sam and Carole were to mate?

The predicted phenotypic ratio of their offspring would be 1 black eyes, green skin : 1 black eyes, white skin : 1 orange eyes, green skin : 1 orange eyes, white skin.
