What is it
- Codominance is a pattern in Non-mendilian genetics. It is when no single allele is dominant over the other, both are present at the same time.
- In codominance both traits are dominant and expressed in the offspring.
- Both alleles will have capital letters.
- Striped animals, checkered, and polka dotted animals are all ways codominance is expressed.
Example 1:

| This could come from a brown cow mating with another white cow. |
Example 2:
Reflection:
After researching this subject I realized that it is capable to have two traits being dominant without having a recessive gene in the offspring. This subject isn't hard to pick up after remembering how to do punnet squares by its rules. This is used almost everyday by scientist to determine what offsprings will come out and look like or what genes it will carry.

Your blog was very well put together and I like how you got right to the point. I do agree that this subject isn't hard and is east to pick up on. Also I think its cool that scientists use this process everyday. I think one thing you could have added is how to remember what codominance means so you don't get it confused with Incomplete dominance.
ReplyDeleteI like how your blog is organized and how you included examples so people can better understand the topic. In your reflection I agree with the fact that it's an easy topic to pick up after knowing how to do punnet squares by the rules and I also found this topic to be fairly easy. I think you maybe could have gone a little more in depth with codominance and talked about the other types of things that can be shown to show what the difference is.

ReplyDeleteI really like how you put things simply and how you organize the information. In response to your reflection, I agree it's fascinating that there can be two dominant genes instead of a recessive one making the organism heterozygous. I think something that's cool is how incomplete dominance is a blend of two traits, but codominance shows both traits.
