How Heredity Works: Summary

   The DNA is a long, complexx molecule that contains the codes that cotrol your cell activities, your chemical makeup, and heredity (continue)

Predicting Traits: Summary

First, a Punnett Square is a table used to predict the outcome of crossing different forms of a trait, and probability is how likely it is for something to happen. A pedigree is a chart used to trace the history of a family, like a family tree. To know how to use the Punnet square, you need to know that the male is up and the woman is in the left; to make the calculation, we are going to use letter G, but you can use whatever letter (remember that "G" is dominant and "g" is recessive)

As you can see, you need to conbinate the letters top right corner with lower left corner etc.
End.

Learning About Heredity: Summary

To start, a dominant trait is a trait that appears in the hybrid generation ... or, in easier words, a trait that is visible, and a recessive trait, is a trait that is hidden or masked in the DNA of the hybrid generation.

  Dominant trait                                              

Recessive trait

Some characteristics that can be inherited: The hair color, eyes color, nose shape, mouth size or shape, height, weight, ear shape, sickness like diabitis, muscles, intelligence etc.

A man named Burbank, was someone who united different kinds of plants to form new ones, he was so succesful making that, that the people gave him the name of the plant wizard.

Geologic Time: Summary

  A fossil is the remains, trace or imprint of a prehistoric living thing preserved on Earth crust.
When a fossil falls on water, normally, new layers start forming under water, that makes that the fossil that was on the top layer be under many other layers.

  Earth have four eras (If you don't know what's "era", you can look for it on google): The Precambrian, Paleozoic, Meseozoic and the era in what we live, The Cenozoic Era.The Cenozoic Era has three
