Babies :) and Genes

Since we have been learning about reproduction and how there are different ways to make a baby these days I thought i would explain a few terms in making a baby! The first term I have learned would be the word: Homozygous. This word sounds like a character out of a Dr. Seuss book but really it means 2 of the same copy of a gene. For example AA, or aa. The opposite of Homozygous is another term Heterozygous which means two different copies of a gene. And an example of this would be Aa or Bb. Dominant and Recessive also play a big role in genetics. A dominant gene is a gene that shows up in a trait. A recessive gene is a hidden gene in a trait. Phenotype is a visible trait in the child for example blue eyes or big ears. A genotype are the genes that make the phenotype the genes that are present. Knowing these terms help so much when we are progressing into the baby making process!!!!
