The most common inherited traits are the freckles, long eyelashes, and free earlobes.parents. This are dominant traits. No flecklers, short eyelashes, and attached earlobes are recessive traits. Sometimes you can inherited the shape of the red blood cell of you.
Exist different type of blood like Type A has only A protein, Type B has B protein, Type AB has both protein, and Type O does not have either of the two proteins. The persons with type O can be donated to anyone, the persons that have this type of blood call universal donor. A person with blood type AB only can give to a person that have the same type of blood, but the persons with this type can recieve any of the four types of blood, the persons with this blood type call universal recipient.


The chromosomes are the ones who determine the sexcell of your child. Exist two types of chromosomes, X chromosomes and the Y chromosomes, if inherit two X chromosomes is female, but inherit one Y chromosomes is male because only males have a Y chromosomes. With all of the inherit traits and that also you can inherit disease like hemophelia, dyslexia, cystic fibrosis, ect..

Summary 7

Every cell of our body have a type of code that controls traits that develop in every offspring.

Inside the nucleus are the chromosomes and all dont have the same amount of chromosomes form example the rabbits have 44 chromosomes, in humans have 46 chromosomes,in grasshoppers have 24 chromosomes, and in carrots have 18 chromosomes.
The gene wich are the one that contain the information needed form cell to functions can be find along a chromosomes. Every organism posses two copies of each gene for a single trait. Exist a code that name DNA that means deoxirybonucleic acid. This have the code to tell cell how to operate.
They are two process by which cells are divided which are mitosis and meiosis. Mitosis occurs in all the parts of the body except in the sex cell and meiosis only occurs in the sex cell.

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.

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.

 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
