Help!?!? 2. 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? (1 point) plants with red flowers and plants with blue flowers plants with both red and blue flowers plants with red flowers, plants with blue flowers, and plants with purple flowers plants with purple flowers

    Okay while I think about how I'm gonna outline this, do you then know what codominance is?

    Okay, codominance means that two genes are expresses well equaly... best example is blood type fx A and B is a codominant and therefore we have a bloodtype called AB. Same goes for the question: Now the plants undergoes both self-fertilization and cross-fertilization, due to the fact that the red and blue flower gene is codominant you can conclude that the original flowers that undergo fertilization most be homozygot with either the blue or red gene. Agree so far? :)

    Just trying to explain the theory, so you can solve a similar problem in the future :)

    So are you saying it would be either A or B?

    No no. That was just to explain what codominance was, that a domiant gene can well "co"rporate"" with another dominant gene creating a mixture between two genens.

    |dw:1357339579882:dw|Well lets try move on then: Now fertilization happens, self and cross. Becuase the P-generation was homozygote we most be able to set up the following lemma: *Self-fertilization: most result in that the follows have their same color becuase if self-fertilization the genes most be then same and we can then do a crosschart that show they all would have the same color (crosschart nr. 1 and nr. 2). *Cross-fertilization: Here there are 3 options/crosses: 1) red-red 2) red-blue 3) blue-blue Option 1 and 3 would give result as in self-fertilization due to the fact they still are homozygote. Option 2 however we need to do a crosschart with both red and blue (crosschart nr. 3). This crosschart only have RB, wich means they contain the gene for red and blue, but sence the two genes are codominant we get a mixture of the two genes. Based on all the theory I have provied, what do you think the answer is? |dw:1357339409928:dw| |dw:1357339490967:dw|

    Well if you're actually explaining to me the question, there arent any purple genes, so my best guess would be either A or B. Looking at the diagrams you drew, im thinking it would be B. (Sorry if im wrong. Im not very good at this.)

    Well there are purple :/ RB would be purple. A mixture between red and blue is purple, and this is where the codominat gene comes into play :/

    So are your diagrams explaining steps or should i consider them all together? Like if it was just explaining steps, i would say its D. But if i consider them all together, i would say its C.

    My diagrams are showing what kind of outpues that can come when the flowers are cross with them self or other flowers. From the diagrams you can then see there will be RR (red) BB (blue) and RB (red and blue - but there are codomiance so a mixture of red and blue = purple)

    No problem, I hope the theory helped to understand so you can answer similar questions your self :)
