i really like this method. but in our test, the teacher premade the punnet square for us which is already the gigantic one HAHAH
Am just a learner, but is d question not saying heterozygous
W
Doesn't show how you get the ratios or why you got .75% and .25 instead of just 75% and 25%.
Completely unrelated to the topic, but I wanted to say your calligraphy is absolutely beautiful!
Thank youu
Que le paso a ella? Donde esta?
Hey tutor u look cool
What if they ask me for the genotype?
helped really in my final examination thanks
Urs is so clear, tnx
"Die- hi- brid" "Big F" "Long things" Outstanding wordplay
Really good job! You are the best, I couldn't understand before watching this video.
this explanation was way easier to understand than what my professor was teaching, thank you
Wow, my teacher didn’t teach us like this. Much easier with two punnet squares!! Thank you so much
"looks like long fang is long gone!"
~where are you now~ mam?
come back mrs k
Yes please
My teacher gave to me with a worksheet and it doesn’t help,,
How would you find the ratios though
Look behind your ear
you can find the ratios simply by using the fork-line method. It is easier.
good explain
Bruh I’m doing this
You say bruh. Gaurantee, you failed.
You just saved my homework
Bruh
What would a dihybrid cross look like if AaBb x AaBb? A = normal skin color, aa = albino skin, absence of normal color, B = brown eye color, and bb = blue eye color.
Idiots
You’re the best
thankyou very much
Alison Perez right lmao
Thank you for taking time into making these videos, it helped me a lot!!!
My professor makes everything so complicated and confusing and can't even explain properly but you make everything so easy to understand. Thank you so much I love all of your videos!!!!!
