Was there a scientific way to predict the outcome of a cross between two parents?

Would the answer beThe Punnett Square

Hello there! 

There was not a scientific way to predict the outcome of a cross between two parents until Gregor Mendel experimented on this. Mendel found that individual traits are determined by "discrete factors" later known as genes, which are inherited from the parents.  

Hope this helps.

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
