BIOLOGY unit 4 SAC heredity

[rachid.kam]

on my sac, i had a question saying how co dominance occurs between white and red flowers and makes pink offspring. in the next part, it said the red flowers have curled leaves and white flowers have straight leaves. what would the offspring have?
Also, it said, given the above information, what can you deduce about this inheritance?

[Gogo14]

Because Red flowers have curled leaves, the gene that codes for the red pigment and the gene for curled leaves are linked (since they occur together)
Similarly with white flowers, gene for straight are also linked.

Pink offspring is a combination of both white and red pigment expression on a microscopic level (like a drawing with blue dots and yellow dots to make a green picture). Hence due to the fact that they are both expressed, you can guess that the offspring flowers should have both curled and straight leaves.

The inheritance is co dominant because the two genes are linked.

correct me plz if im wrong

@Gogo 14, thank you for saving my life. i wrote that on my sac and have been anxiously waiting to know if i got it right. Thank aqain. btw, did you finish or still doing biology in year 11?

[Gogo14]

Still doing bio. Honestly, dont take my word. It is just what I would have said. I trust you will do well tho

While I am in the HSC course for Bio, we do cover co-dominance in quite a bit of detail.
I mostly agree with this except for the part in bold. The way it got taught to me is that if straight leaves and curled leaves both are expressed, you will find yourself with "semi-curled" leaves.

The reason why there is not just straight and curled leaves is the same reason that white and red flowers make pink flowers and not just more white and red.

Feel free to argue against my points but i am pretty sure thats how it goes from my experience.

Hope I help
