1. Thanks for the﻿ lesson!

2. thank you sooo much!! you’ve just expalined it well. its a really great help﻿ especially i’m having a demonstration in our class :))

9. True. I did sacrifice time for﻿ quality 😉 Thanks for watching all the same!

10. contrary to the first seconds of the video, this is most definitely Biology in 8 minutes.﻿

11. thanks, I needed a good way to differentiate incomplete and codominant alleles for my exam. The subscripts work﻿ well, thanks!

12. GOOD! ﻿ Glad I could help 🙂

13. Thank you so much. You cleared up﻿ ALL my questions and I’m probably going to ace the exam because of you

14. George Lucas?

15. This was so﻿ clear. Thank you.

16. I’m sure different teachers demonstrate this differently. The basics of the problem still work. In other words, the letters you used work just fine and you will﻿ get the same phenotypic ratio. However, the problem comes with using rr. Technically incomplete dominance both red and white are BOTH dominant and there is no recessive trait. Since we use lower case letters for recessive traits, I don’t like using them for a non-recessive trait. Make sense?

17. aren’t you supposed to use the same letter like for red flowers RR, for white﻿ flowers rr, and for pink flowers Rr

18. Thank you so much! This helps me understand things﻿ so much better!

19. or u could say green (50%) is 2/4. usually ur genotype will be out of four. so 2/4 is 50 percent and 1/4 is 25% and 3/4 is 75% and﻿ 4/4 is 100%. think of it like quarters ^_^

20. thanks,﻿ rlly easy to understand.

21. not sure﻿ if this helped….

22. How can I pay attention to the lesson when there is a video of baby with﻿ 3 arms on the related vids?

23. It is a common mistake and LOTS of teachers actually get is backwards. For further information try: h t t﻿ p : / / w w w . emc.maricopa.edu/faculty/farabee/biobk/BioBookgeninteract.html

24. That is what is says on the screen.
25% Blue (which is 1/4)
50% green (which is 1/2)
25% yellow (which﻿ is 1/4)

25. Fractions, percents, and decimals are﻿ all the same thing. .5 is 1/2 is 50%. There is no difference in any of those.
