GENETIC CROSSES w THE MONOHYBRID CROSS w THE DIHYBRID CROSS
First: Set up the Parental Cross P 1 è A = axial flowersMale è a = terminal flowers Female è AA X aa
SET UP THE PUNNETT SQUARE
Put the Alleles in Separate Boxes
A Monohybrid Cross
Now Perform an F 1 Cross è A = axial flowersMale è a = terminal flowers Female è F 1 = First Offspring è Aa X Aa
Put the Alleles in Separate Boxes
Perform the Cross
Assess The Genotype and Phenotypes è GENOTYPES è AA 1 è Aa 2 è aa 1 è Ratio 1:2:1 è PHENOTYPES è Axial Flowers (AA, Aa) 3 è Terminal Flowers (aa) 1 è Ratio 3:1
Assess The Genotype and Phenotypes è PHENOTYPES è Axial Flowers 3 è Terminal Flowers 1 è Ratio 3:1 è GENOTYPES è AA 1 è Aa 2 è aa 1 è Ratio 1:2:1
First: Set up the Parental Cross P 1.. F =flyingf = walking è è P = purple p = orange è è FFPP X ffpp è è MALE FEMALE
PARENTAL P 1 DIHYBRID CROSS
.. F =flyingf = walking è è P = purple p = orange è è Do the F1 cross è è FfPp X FfPp è è Be sure you choose one of EACH type of allele
F 2 DIHYBRID CROSS

How to do a Dihybrid Cross using a Punnett Square What two traits are we looking at? Assign letters to represent the dominant and recessive alleles for.
Mendels Laws of Heredity Why we look the way we look...
Unit 4 – Lecture 6. Dihybrid Cross a 4x4 representation of crossing TWO traits monohybrid = 1 trait w/ 2 alleles = 1 allele gamete each for 2x2 box dihybrid.
Dihybrid Cross Notes. 1. Determine dominant and recessive traits Carefully read the problem.
Mendel and Monohybrid Crosses Notes. Gregor Mendel Mendel was an Austrian monk. Mendel formulated two fundamental laws of heredity in the early 1860's.

MRs Jackie Principles of Genetics Part II. Terminology Allele- alternative form of a gene for a certain trait. Example seed shape R and r, and flower.
Dihybrid Crosses **Crossing 2 different traits at the same time.
Todays Objectives TSW employ the four primary rules for solving genetics problems. TSW successfully solve genetics crosses involving one and two alleles.

Steps to solving Punnett Squares. Example # 1 In a certain species of mouse, pointed ears are dominant over round ears. Predict the genotypes and phenotypes.
Aim: Why did Gregor Mendel’s experiments with pea plants lead to the science of genetics? Text Ch 11 Introduction to Genetics Read pages 262 – 269 HW.
Warm-up Complete these crosses. Give the possible genotypic results and phenotypic results. 1.Free ear lobes are dominant to attached ear lobes in humans.
CHAPTER 9 INTRO TO GENETICS. INTRODUCTION TO GENETICS.
Types of Chromosomes a. Autosomes Any chromosome that is not a sex chromosome. 1 to 22 b. Sex Chromosomes A chromosome involved with determining the sex.
Words to know… Heredity - the passing of traits from parent to offspring. Genetics - the study of heredity. Trait- a specific characteristic Gene- chemical.

Problem #1 X H = Chromosome with allele for Normal Blood Clotting X h = Chromosome with allele for Hemophilia Y = Chromosome without an allele for blood.
Using a Punnett Square. What is a PUNNETT SQUARE? If you know the genes of the parents, a Punnett square can be used to… show the different ways alleles.

More Punnett squares. Complete Dominance Involves dominant and recessive alleles dominant allele always overpowers the recessive allele in appearance.
