Chapter 5: Heredity
Chapter 5 was about Mendal and His Peas, Traits and Inheritance, and Meiosis. All these sections tie up to heredity.
Section 1: Mendal and His Peas
Vocabulary:
1. Heredity: The passing of genetic traits from parent to offspring.
2. Dominant trait: The trait observed in the first generation when parents that have different traits are bred.
3. Recessive trait: A trait that reappears in the second generation after disappearing in the first generation when parents with different traits are bred.

Section 1:Mendal and His Peas Summary
Section 1 was about Gregor Mendal and his life and findings in science;it was also about his experiments, for example for his first experiments Mendal crossed pea plants to study seven different characteristics. He crossed plants that had purple flowers with plants that had white flowers, the offspring from such a cross are called first-generation plants. In his second experiments he allowed the first-generation plants to self-pollinate. Some important vocabulary are heredity, dominant trait, and recessive trait. Heredity is the passing of genetic traits from parent to offspring. A dominant trait is the trait observed in the first generation when parents that have different traits are bred. Last thing is a recessive trait which is a trait that reappears in the second generation after disappearing in the first generation when parents with different traits are bred.
Section 2:Traits and Inheritance
Vocabulary:
1.Gene:One set of instructions for an inherited trait
2.Allele:One of the alternative forms of a gene that governs a characteristic ; such as hair color
3.Phenotype:An organism's appearance or other detectable characteristics
4.Genotype:The entire genetic makeup of an organism; also the combination of genes for one or more specific traits
5.Probability:The likelihood that a possible future event will occur in any given instance of the event

5.Probability:The likelihood that a possible future event will occur in any given instance of the event
Section 2:Traits and Inheritance Summary
Section 2 was about traits and inheritance and phenotypes and genotypes.A phenotype is an organism's appearance, both inherited alleles together form an organism's genotype. It also discussed punnett squares. A punnett square is used to organize all the possible combinations of offspring from particular parents.
This is a picture of a fish going through time and at the end he looks like father because his father probably had the dominant trait so the fish is going to look like his father more.
Section 3:Meiosis
Section 3 was about asexual reproduction,sexual reproduction,meiosis,genes and chromosomes,the steps of meiosis, and meiosis and Mendel. In asexual reproduction, only one parent cell is needed;this type of cell reproduction is known as mitosis. In sexual reproduction, two parent cells join together to form offspring that are different from both parents.
