In Which I Discuss Genetics

     We might not all have the working knowledge of genes that a geneticist with a PhD would have, but we still have a general knowledge. "He gets his eyes from his mother!" "Toby's freckles are a family trait!" "Well, I inherited my curly hair from my mother!" We're talking like scientist without even knowing it. Now some things (like rolling your 'r's' and musical ability) are kinda sketchy, as it is not yet proven that those things can be inherited through genetics (i.e. it's all hokey). As for genes and DNA, how does it all work?
     To get a general idea of what genetics are I have made a sort of graphic organizer to show you the basics.

     Also relating to genetics (specifically Alleles and genes passed on) is the Punnet square. Each little phenotype for parts of DNA and genetics is determined by these little boxes. As was listed in the results, the dominant is Capitalized (or mixed) and recessive is lower case. A punnet square shows all the possibilities and outcomes. Pretend the flowers and genotypes represent the possession of freckles and the punnet square may make more sense.

     So with a little vocabulary and a hint of working knowledge, follow this link to see how this applies to makin babies!
