Question

Help understanding biology question?

A woman buys red-flowering and blue-flowering plants of the same species and plants them in her garden. The plant undergoes both self-fertilization and cross-fertilization. The woman collects seeds and plants them the following spring. What can the woman expect to observe in the flowers of the new generation of plants if the gene for flower color is codominant?

Answer 1

When we're talking about the height trait of pea plants,
we know that TALLNESS is DOMINANT,
and SHORTNESS is RECESSIVE.

TALLNESS and SHORTNESS are two possible phenotypes for the same trait -- HEIGHT.

One of the phenotypes is DOMINANT (Tall)
while the other phenotype is RECESSIVE (short).

~~~~~~~~~~~

CODOMINANCE is where there is MORE THAN ONE dominant phenotype, for the same trait.

Take a look at your question.

The trait we're talking about, here, is flower color.
FLOWER COLOR is the TRAIT.

And the PHENOTYPES, that are mentioned in the question, are RED, and BLUE.

What that means is that if a RED flower and a BLUE flower breed together,
they might produce a flower that is BOTH RED and BLUE.

Usually, only one color will show up.

But with CODOMINANCE,
BOTH colors can show up.

Now, if you remember back in elementary school art class,
you remember that RED + BLUE = PURPLE.

So, if a RED flower and a BLUE flower cross,
you might get a PURPLE flower.

I can see places where someone might be confused.
