Co-Dominant Traits in Aliens

This video tutorial guides students through Activity B, focusing on how alien skin color is inherited. It begins with setting up the gizmo, creating green and pink aliens, and making predictions about their offspring. The concept of co-dominance is explained, where offspring show a mixture of parental traits. Students conduct an experiment by breeding aliens, recording results, and analyzing the data. The video concludes with a discussion on co-dominant traits and whether offspring always resemble their parents.

What is the main question being explored in Activity B?

• How do aliens communicate?

• How is alien skin color inherited?

• What do aliens eat?

• How do aliens travel?

What are the initial colors of the parent aliens in the experiment?

• Purple and Orange

• Green and Pink

• Red and Blue

• Blue and Yellow

What is a co-dominant trait?

• A trait where offspring show a mixture of both parents' traits

• A trait that is always recessive

• A trait that skips generations

• A trait that is always dominant

What was the result of breeding a green alien with a pink alien?

• A completely new color

• A pink alien with green spots

• A green alien with pink spots

• A blue alien

How many times were the aliens bred in the experiment to record results?

• 5 times

• 10 times

• 15 times

• 20 times

What was the most common skin color observed in the offspring?

• All green

• Blue and yellow

• All pink

• Green and pink

Did all offspring have the same skin color?

• Yes, they were all pink

• No, they were all different colors

• No, some were green and some were green with pink spots

• Yes, they were all green

What does the experiment suggest about co-dominant traits?

• Offspring always look like one parent

• Offspring traits are unpredictable

• Offspring never look like either parent

• Offspring can show a mixture of both parents' traits

What was the final ratio of green to green and pink offspring?

• 5 green and 5 green and pink

• 4 green and 6 green and pink

• 6 green and 4 green and pink

• 7 green and 3 green and pink

Do offspring of identical parents always look like the parents in co-dominant traits?

• Yes, but only in some cases

• No, they can show a mixture of traits

• Yes, they always look identical

• No, they never look like the parents
