he had to be in order to have a Blonde daughter, he had to carry the blonde trait so his daughter could be blonde (bb) Otherwise if he was pure brown haired (BB) there would be no little b (blonde trait) to give his daughter, this would have made her a brunette, not blonde.
What do you do about someone on a pedigree who's genotype you are not sure about? Some people could be Homozygous Dominant or Heterozygous, and you cannot tell by looking at their parents of offspring. Do you then half-shade them or not half-shade them?
That is a good way to represent it genotypically. However, if the individual is actually Bb, they should be half-shaded, and if they are BB, they should not. Since there are usually people like this in a pedigree, I don't let my students do half-shading and have them write both possibilities under the individual (BB/Bb). That way the shading is not being potentially misrepresented.
Couldn't the last girl on the bottom right also be Bb tho? Which would still be dominant... the only way to know for sure is to see what kind of offspring she has.
I'm sorry, but I watched that video at times 2 speed, and it was still pretty slow. It taught me what I needed to know, so thank you, but the pacing of the video is pretty off.
This video is getting 1000 views today because our teacher made us watch this and we needed this for class work so there will be a lot of rewatching going on here XD.
I dont understand why the mom and dad are 'bb' and 'Bb'. why cant the mom be 'Bb'? and if thats a possibility, then why is the sun 'bb'? I have a test coming up, where she will have us figure out who is what. This video kind of confuses me.
Lena Katherine because "B" is the dominant allele. Which is brown hair. Since the mom is blonde she has the recessive allele, "b".The dad has to be a carrier for blonde hair because if he was homozygous all of their offspring would be brown haired.
Lena Katherine This is because blonde hair is a recessive trait and can only come up when both blonde alleles (bb) comes up. But to have brown hair you need either Bb or BB because brown dominates blonde. For the blonde son the father must have Bb for the son to have bb. When it comes to passing down traits it's random.
You're correct - in some situations however it is important to introduce these types of concepts in a way that people can visualize. Referencing humans when teaching humans is one of the best ways for us to grasp a concept. In this type of a introduction it may have been better to analyze the inheritance pattern of one of Mendel's identified pea traits.
Looks like the gene of not having a nose was kept in this family tree.
😂😂😂😂😂😂
Nose's are too mainstream

@@Sarah-sh1qy Those emojis don't have noses either!😊
The blonde haired boy got friendzoned
Robin Hood lol
How sad
When
I love the emphasis on 'once married - they reproduced' … LOL
Same as Richard, I'm not going to show this in science class because being married is not relevant to producing offspring.
Mmm, yes, I too thought that was interesting. Must be a pretty family-friendly Christian Minecraft-only TH-cam channel or something.
@smalta101 me too
Cause that’s how it’s supposed to be
WHERES THE MUSIC LINK
good video but i especially liked the 80s porn music
lmfao
oh yeah yeah
@@Woah6990 shut the fuck up
Thomas Muller o-
why lmfao omg
that moment you realize this guy is getting view because teachers make students watch it like if you agree
Harambe made me watch this
Syrian children made me watch this
hahahahaha
Stay_Finnessin my teacher made me watch this
You mean you guys don't do this of your own choice?
The female of the right bottom could also have been heterozygous, could you tell the difference?
wait, how did you know that the last daughter - the brown haired one - wasn't a carrier? (Bb)
pause
Because he made it up...
I
I know it has been 5 years but on a punnett square, there is a 25% chance that she would be BB. Whoever made the video just choice BB over Bb.
really explains it well now i feel more confident for my exam
I feel sorry for the first born boy. Wish he finds someone soon 😇
Because of this, I now understand the pedigree chart. Thank you so much
Somehow I understand it less
In the example, is there a way to find out if the son in law was indeed hererzygous or was that given in the statement?
he had to be in order to have a Blonde daughter, he had to carry the blonde trait so his daughter could be blonde (bb)
Otherwise if he was pure brown haired (BB) there would be no little b (blonde trait) to give his daughter, this would have made her a brunette, not blonde.
How do you know if the parents is dominant or recessive?
What do you do about someone on a pedigree who's genotype you are not sure about? Some people could be Homozygous Dominant or Heterozygous, and you cannot tell by looking at their parents of offspring. Do you then half-shade them or not half-shade them?
Nice presentation and well thought out cognitive application.Very useful for class demonstration.Thanks a lot Benjamin.
In this example it would be B-
That is a good way to represent it genotypically. However, if the individual is actually Bb, they should be half-shaded, and if they are BB, they should not. Since there are usually people like this in a pedigree, I don't let my students do half-shading and have them write both possibilities under the individual (BB/Bb). That way the shading is not being potentially misrepresented.

Both
what software was used to make video like this?
could the brown haired daughter (granddaughter) also have Bb gene
This really helped me complete my biology work. Thanks!
this does not help with the worksheet I'm doing in pre ap biology ugggggg
Song name?
Couldn't the last girl on the bottom right also be Bb tho? Which would still be dominant... the only way to know for sure is to see what kind of offspring she has.
HOW ARE YOU SUPPOSED TO KNOW WHAT LETTERS THEY ARE
For example if there was a girl with brown hair write b
My teacher made me watch this lol
Mine too
Me too
Harambe made me watch this,,,, was not disappoint

Bus number 73 made me watch this

it's perfect speed for my middle school students.

That was easy,sir!Thank you~
Perfect explanation, thank you!
I rate 9/11

I'm supposed to be doing homework, but I can't stop laughing at all of the comments. Ha ha!
Care
Thank you, Mark! Very cool!!
thanks bro, really helped me with my assignment
why are you talking as slow as possible
are you *trying* to make the kids in class fall asleep?
thank you! so much! I use it to my report this morning! :)
thank you
omg the background song was waiting on the world to change! Right?
no
nope
Great video :) Thanks so much!
Brilliant
Thank you!!! I really didn't get it before, and now i do!! Thanks so much
Thank you for making this video it helped me clarify a few things and learn a few new things too. Keep it up
Thank You it really helped for My biology class❤️
Nice explaining all this.
nice video got headache from voice and music
That music better be royalty free or your channel is outta here
Thanks for this summary.

i had to watch this for my school work
I came here for dog food...
Wrong place.
Helpfulness level 99999999999999
thanks for the vid i love you i learnd alot
If the father was brown hair then shouldn't it been BB
Alvin Yang
No, because brown was dominate
Could have been Bb (heterozygous)
Fabulous. ...
Helped me a lot thanks
thank you so much i understand this so much better now :D
my right ear enjoyed that..
My left nut enjoyed that
