high school biology book question

[Henk69]

Extended black is dominant but I agree "dominant black" is not the best term.
It is used with mammals though.

the book is "a glencoe program Biology: the dynamics of life". if any one ever gets to look at this book it talks about the "checkered chickens" on page 316-317.

i'll be sure to give my teacher this link. Maybe she'll give me bonus points for finding this out

oh and we did talk about the red and white flowers producing pink flowers, but that was for incomplete dominance that shows a third phenotype.

Tim! It is good to see you back online!

A few years back I read an article about science textbooks (I think that it was mostly referencing elementary level texts), and how many of them have seriously incorrect information. It mentioned specific examples in a variety of major brands of textbooks. It was long enough ago, that I would have hoped that attrition and newer publications had removed the problem.

When I finish lunch I am going to walk down to the science lab and make sure the teachers are not using this book.

There is a type of carnation taht displays both red and white; don;t know what the variety is called, and I don;t know enough about plant genetics to know if it is truly co-dominance or not, but I think that Mendel produced both incomplete and co-dominance with various pea experiments.

They would have been better off using codominant black and white dragons in the example. They would have a harder time confusing the students who had knowedge in their heads before they got to class!

Some Rose of Sharon [Hibiscus Syriacus] will display Red and White in there blossoms.

I'm wondering if anything and white is a good example? And whether a better example would be two different colours of different pigments? For example, splash can look like black and white, but it is really not even close to co-dominance as it is varying dilution of one pigment. Red and blue or yellow and purple might be better examples. Assuming one could find the examples, lol.
