Father of genetics ?
Three reasons why did Mendel use pea plants?
Reproduction rate, visible traits, easy to cross
Mendel determined that __ traits will always show if there is an allele for it.
State the principle of segregation,
Allleles separate during meiosis
State the principle of independent assortment and give an example.
Alleles for one characteristic assort or divide up among the gametes during meiosis, independently of alleles for other characterisitics example: Dihybrid cross
What is probability?
Chance of an event happening
How is probability figured?
# of events of choice /# of possible events
How do you calculate the chance of two individual events happening?
Multiple the individual chances.
The larger the sample the __ the deviation.
How is deviation computed?
Expected-actual + expected- actual/# of attempts
What are the chance when tossing 2 coins to get H/T?
The exact same alleles
What gametes can be produced from TtGg?
TG, Tg, tG, tg
What is the genotype ratio of the cross of two monohybrid heterozygous traits?
1 homozygous dominant:2 heterozygous:1 homozygous recessive.
If G is green and g is yellow If R is round and r is wrinkled If T is tall and t is short What is the genotype for:Heterozygous green, wrinkled, homozygous tall plant? And what gametes could be produced?
GgrrTT GrT, grT
What is the phenotype ratio of a dihybrid heterozygous cross?
What is X linked?
Alleles found only on the X chromosome
Cattle with Roan coat (red and white) are the result of ___ pattern of inheritance
What three patterns of inheritance do blood types display
Codominance, dominant/recessive, multiple alleles
A mother with type O blood and father with type AB blood could have children with what types of blood? phenotypes
What happens when different blood types mix?
Blood clots/clumps because the anti bodies are attacking the foreign substance.
Universal blood donor?
What genotype can not be determined by the phenotype?
Picture of the paired chromosomes
Is it possible for a female to be colorblind-explain your answer
Yes. Father is CB and mom is either Cb or a carrier
What type of inheritance might this show?
Multigene, or multifactorial trait
Cause of most extra chromosomal disorders.
Mendelian Genetics. How Genetics Began A monk named Gregor Mendel first studied how certain traits could be passed on by studying his pea plants. Heredity.
Mendel Genetics Monohybrid Crosses Dihybrid Crosses.
Chromosomes §Humans have 23 pairs of chromosomes. §The autosomes refer to pairs They are identical in both males and females. §Pair #23 is the.
1 Review What is probability Use Models How are Punnett squares used to predict the outcomes of genetic crosses 2 Review What is independent assortment.
Mendelian Genetics. Let’s Review How are traits coded? Where are genes located? Chromosomes are composed of what macromolecule?

Inheritance of Traits.
Basic Genetics Gregor Mendel The Father of Genetics.
Chapter 10. Mendel’s Laws of Heredity Who is Gregor Mendel? –Mid 19 th century (1865) –Austrian monk –Loved statistics –Enjoyed gardening –First to apply.
Genetics. What is Genetics Genetics is the scientific study of heredity. Heredity is what makes each species unique.
Genetics Chapter 11. What is Genetics Genetics is the scientific study of heredity. Heredity is what makes each species unique.
Final Concepts for Chapter 11 Mendelian Genetics Allele Allele Dominant Dominant Recessive Recessive P-generation P-generation F1 generation F1 generation.
Probability & Genetics. .A. Learning goals Explain the random process of chromosome segregation and distribution of alleles in gametes. Predict possible.
Heredity Standard B-4.6 Predict inherited traits by suing the principles of Mendelian genetics (including segregation, independent assortment, and dominance).
Who was Gregor Mendel (biographical information)? What did he study? Why did he use pea plants for his research? What were his results? What.
Define the following terms: – Homozygous – Dominant – Law of segregation – Monohybrid cross – F1 generation – Test cross Who was Mendel and what did he.
Applying Mendel’s Principles Probability, Punnett Squares, & Independent Assortment (Dihybrid Cross) Section 11.2.
GENETICS The study of how hereditary information is passed from parent to offspring.
Guided Notes – Mendelian Genetics
6.5 Traits and Probability KEY CONCEPT The inheritance of traits follows the rules of probability.
1. Who is named the “Father of Genetics?” Gregor Mendel 2. Why did he use pea plants? To study the inheritance of traits.
Genetics: Basic Inheritance Ch & 2. Genetics Genetics is the study of heredity. Genetics is the study of heredity. Traits are controlled through.
Genetics The Study of Heredity.
1. Who is named the “Father of Genetics?” 2. Why did he use pea plants?
Mendel’s Second Experiment Inheritance of Two Traits Dihybrid Cross.
Mendel & heredity mysteries-at-the-museum/video/blue- people-roaming-the-hills.
Mendel noticed similar results every time he performed a certain cross. Example: Whenever Mendel crossed two plants that were hybrid for stem length,
Punnett squares illustrate genetic crosses.
DNA – double helix DNA coils to form a chromosome You receive 1 set of chromosome from mom & one from dad Chromosomes have areas that code for a gene.
Probability The principles of probability can be used to predict the outcomes of genetic crosses Think of probability like flipping a coin. If you.
