Gregor Mendel

Gregor Mendel. Mendelian genetics explains the principles of heredity. Why Pea Plants???. have easy to identify reproductive organs easy to grow have a short generation time could be cross-pollinated ( produces seeds that are the offspring of two different plants). Genes

Genetics and Heredity

Genetics and Heredity. Traits and Genes. A trait is a specific characteristic, such a eye color or height, that varies from one individual to another Today scientists call the chemical factors that determine traits genes. Are these inherited traits?. Your eye color.

Mendelian Genetics

Mendelian Genetics. Dihybrid Crosses. I. Law of Independent Assortment. A. Dihybrid Crosses 1. move from monohybrid to dihybrid cross 2. dihybrid-investigating the inheritance of two traits at one time 3. question to be asked is a. Are two genes inherited as a package?

Genetics Take 2

Genetics Take 2. Dihybrid Crosses. Monohybrid vs. Dihybrid. Monohybrid crosses are crosses that examine the inheritance of only one specific trait. Dihybrid crosses are crosses that examine the inheritance of two different traits. Mendel and Dihybrid Crosses.

Dihybrid Crosses

Dihybrid Crosses. Why Dihybrid ?. Sometimes there are traits in the genotype that are linked The traits that have two genes require a special punnett square. Why Dihybrid?. When there are two genes we use a dihybrid cross

Dihybrid Crosses

Dihybrid Crosses. Crosses involving two traits. Dihybrid Crosses. Constructing a Punnett square for a dihybrid cross is similar to the method used for a monohybrid cross First, determine the alleles produced in the gametes of each parent Next, construct a Punnett square

Law of Independent Assortment

Dihybrid Crosses. Law of Independent Assortment. Law of Independent Assortment. Alleles for different traits are distributed to sex cells independently of one another. This law can be illustrated using dihybrid crosses. Dihybrid Cross.

-A dihybrid cross is a way to predict the genotype and phenotype of an offspring

Dihybrid Crosses. -A dihybrid cross is a way to predict the genotype and phenotype of an offspring -The dihybrid cross is a probability, not an absolute certainty -A dihybrid cross analyzes the probability of two genes together on a chromosome (ie. Color AND size, shape AND position, etc).
