Back in the day, Mendel was working on those pea plants
How is it he wondered, some are small and some are Gi-ants, For he would cross two talls and notice one in four were smalls.
What is causing this? Someone help this monk brother out, y’all! Dominant, when an allele or trait must be expressed
Recessive, then, well it will always be suppressed There are just TWO of them, –Two alleles for every gene,
That’s right and one will win, one will win. Is it hybrid, or is it purebred?
The alleles will show, (Hey!) yeah they will show (Hey!) Heterozygous, or Homozygote,
How can we know? (Hey!) How can we know? (Hey!) Just by looking at alleles found in their
DN-NNNNNNNNNNNNNNNN-A All traits you inherit from your father and your mother,
They are parts of you, like your skin tone and hair color, Any trait you can see is what we call a phenotype,
And anything that’s just a gene we call a genotype With the punnett square, We can predict a baby’s genes,
so start from outside-in, Move up to down, left to right, and It’s so easy, man, You now see the probability,
And percentages, percentages Fertilized, these eggs are fertilized,
Baby, baby, pollinate and they are fertilized Fertilized, these eggs are fertilized,
Baby, baby, pollinate and they are… WHATCHA CALLIN’ IT!
