Traits, Genes, and Alleles 6.3 6.4 TERMINOLOGY FOR THE SUCCESS OF GENETICS
FATHER OF GENETICS
Term: TRAIT Biological factor being studied. Example: A blood disease like hemophilia or bleeder’s disease!
Term: DOMINANCE: THE PREDOMINANT FORM OF A GIVEN TRAIT. Example: Brown eyes are dominant to blue eyes.
Term: RECESSIVE A form of a trait not expressed frequently. Example: Being left handed!
Term: Gene A DNA unit of heredity located on a chromosome that controls traits! Example: Look at the “Human Genome” chart on the side board that shows genes for given characteristics!
Term: ALLELE A gene for a given trait: Examples: A B or O for blood types
Term: HYBRID A condition resulting from the cross of two, pure, contrasting traits of a given characteristic such as eye color. Example: BB x bb Bb = Hybrid!
Term: PHENOTYPE Physical appearance of a given characteristic. Example: Type A blood Eye color - Brown or blue Right or left handed
Term: GENOTYPE The allele expression of a given characteristic. Example: BB, Bb, or bb. BB - HOMOZYGOUS DOMINANT bb - HOMOZYGOUS RECESSIVE Bb - HETEROZYGOUS

6.3 Mendel and Heredity Set up Cornell Notes on pg. Topic: 6.4 Genes, Traits, Alleles Essential Questions: 1.Explain why an organism’s genes may be homozygous.
Genetics Chapter 3, Section 1. Gregor Mendel is considered the “father” of modern genetics. Studied pea plants. Gregor Mendel.

Genetics Chapter 3. Mendel is considered the “father” of modern genetics.
May 4, What is an allele?. Genotype: genetics of trait (what alleles?) Homozygous: two copies of the same allele –Homozygous dominant (BB) –Homozygous.
Genetics. Mendel Studied pea plants. Traits: something passed from parent to child.
Passing traits from parent to offspring.. Physical characteristics inherited by the offspring from the parents. Ex. Hair color Eye color Skin.
Organisms have thousands of genes, organized into chromosomes, which determine what the animal looks like and what it can do.
Genetic Terminology. What makes these two individuals so similar?
Genetics Key Terms Genetics- is the study of heredity. Heredity- is the passing of traits from parents to offspring. Trait- a characteristic like hair.
Punnett Squares and Heredity Quiz Trivia!. Rules Each topic has 5 questions. You will have 2 minutes to answer each question with your group, assign.
Chromosomes are made of DNA. Portions of DNA that code for a trait are genes. Homologous chromosomes have alleles (different versions) of the same genes.
Genetics Vocabulary Terms Working Problems Monohybrid Crosses.
Heredity and Genetics “Why We Look the Way We Do”.
Heterozygous vs Homozygous. Pairs of alleles can be either heterozygous or Homozygous. An allele are a pair of genes (section of DNA).
Vocab 1.Gene- Units of heredity; segments of DNA on chromosomes 2.Allele- different forms of the same gene; represented by a letter (“B” or “b”) 3.Dominant-
Essential Vocab Genotype – the symbolized form; gene forumula (ex: BB) Phenotype – physical appearance/description (ex: brown) Homozygous – 2 genes that.
Genetics = The study of heredity/how characteristics are passed from parents to offspring.
Probability and Heredity What is the difference between phenotype and genotype? What is the difference between homozygous and heterozygous?
REVIEW GENETICS- the study of heredity. Inheritance Traits are specific characteristics inherited from parents Genes are the factors that determine traits.
Who is this man?. That was Gregor Mendel, the “Father of Genetics”. He was a scientist and a monk who lived in the 19th century in Austria. He became.
INTRODUCTION TO GENETICS Chapter 10. Genetics Genetics: the study of heredity Heredity: the passing of characteristics from parents → offspring Characteristics.
Heredity The study of the passing on of traits from parents to kids. Learn how and why physical and behavioral characteristics are passed on to from.
Genetics is the study of how traits are inherited in offspring.
Genetics = Study of Heredity. Introduction A. Heredity = passing of characteristics from parent to offspring a.Trait = characteristics that are inherited.
1. Copy this down on your genetics notes from yesterday…. Gregor Mendel- Father of genetics.
What is Genetics? Genetics is the scientific study of heredity.
Genotype & Phenotype. PhenotypeGenotype HeterozygousHomozygous.
Heredity, Genetics Punnett Squares & Probability Mr. Miller.
1 Mendelian Genetics. 2 Gregor Mendel The Father of Genetics.
Chapter 5. Mendel’s Work Gregor Mendel’s work allowed us to understand why plants and animals are the way they are. Hereditary is the passing of physical.
What is the difference?. Vocabulary Heredity – passing of traits from parent to offspring Traits – the physical, social, and emotional qualities of.
Genetics Review. Who is the “Father of Genetics”? Gregor Mendel What organism did Mendel use to study genetics? Pea Plants.
Genetics: The Science of Heredity. Heredity: The passing of physical characteristics from parents to offspring.
Heredity The passing of traits from parent to offspring Traits: physical characteristics of an organism –Example: eye color, hair color, & height.
Genetics Vocabulary You need to know these!!!. TRAIT A distinguishing feature that a person has Examples: Brown hair Freckles Widow’s peak Blue Eyes.
Dominant and Recessive Traits Cornell Notes: How are traits different? Are some traits more common than other traits? 1/23/14 & 1/27/14 Pd. 1 = pg. 77.
Genetics. Heredity Passing of genetic traits from parent to offspring Gregor Mendel discovered the principles of heredity while studying pea plants (“Father.
Mendelian Genetics. Vocabulary Terms 1.Allele- different forms of a gene 2.Phenotype- observable trait or characteristic 1.I.e. Green eyes, black hair.
Do now question What is genetics and why do scientists study genetics?
Genes Observable traits are the result of genes. – Genes are found on the chromosomes in our cells – Each observable trait is determined by two genes,
Principles of Heredity. Genetics – study of heredity => transmission of traits (genes) from one generation to another parent => offspring.
Punnett Square Part 2 A punnett square is used to show the possible allele (gene) combinations for the offspring of 2 parents. The four boxes represent.
Genetics Review!. What is the genetic material of all organisms made up of 2 twisted strands of sugar- phosphate and nitrogen bases? Question 1.
The Story of Genetics It takes two, to make one!.
Genetics Basic rules… Lots of info is being researched by the Human Genome Project….
Genes and Alleles. Genes Our DNA contains thousands of genes A gene contains all the information and instructions for a particular trait (ex. hair colour,
Genetics Terminology Dominant - trait which stays visible Recessive - trait which disappeared Alleles - alternate forms of a gene for a trait Genotype.
Mendelian Genetics. Gregor Mendel a monk that taught natural science to high schoolers - interested in how traits are passed on -Bred snow pea plants.
