Genotype and Phenotype Ratios and Percents ( Punnett Square Basics)

Learn how to solve Punnett squares. In this video, I review how to write genotype and phenotype ratios and percents.
Key topics covered include solving a monohybrid cross, how to write homozygous, heterozygous, and recognizing dominant and recessive.

with different variations and soo many examples....its was a great lesson!

thank you so much, this really helped me understand my genetics unit in biology !! xx

I'm glad to see I'm not the only person who suddenly got this video loading all the rime

[TheNaffineMachine]

Great video, really informative! keep up the great work 😀

[lilmissy]

It really helped practice with you!! I will A’s this exam >;D tyyyy

I am a biology teacher. I am afraid that I have to point out two mistakes in this video.
Firstly, I have never heard of heterozygous recessive alleles. Do you mean heterozygous alleles? It includes a pair of a dominant allele and a recessive allele, which will show the observable characteristic of a dominant allele.
Secondly, a heterozygous white rabbit shouldn't have Tt to be its genotype. It should be written as Ww. The letter should be determined by the dominant allele.

my exam starts in an hour yall im f*cking cooked

[Yahoooo.]

Thank you kind mister, you really saved my live with that one.

[namuganzanoerine]

It is great to have such lectures.we appreciate

[Nabbbelion]

I don't understand how you get the percentage

[gamerph]

THIS HELPED MEEE THANK YOUU!!!! GOD BLESS YOU !!

[PowerOfTheBanana]

This was super helpful and great extra practice. Thanks!

On your first problem, will there actually be 4 chances that the offspring will result in a recessive phenotype? I'm a little confused on this one.

[iyanechauz]

Thank you so much this help me verry well explained

[meryemkircal]

Thank you so much, this helped me a lot for my assignment.

[makereh]

how would you find the ratio if it was - BB and bb

[youtubeviewer]

thanks man this actually taught me something

[maryannginga]

Help me to figure this out!!!
Predict the phenotypic ratios offspring when a homozygous white cow is crossed with roan bull. Illustrate using punnett square.

[amandacunliffe]

Do you have worksheets I could practice with?

[ziyuchen]

it's beneficial! thank you, but hope we can talk from easy questions to tricky question
