Genetics

Genetics. A. The work of Gregor Mendel. 1. Monohybrid crosses. 2. Dominant and recessive alleles. 3. Law of Segregation. B. Mendel and meiosis. Who was this Mendel and what the heck is he doing in a monastery?. born in 1822. trained himself to be a naturalist early in life.

Dihybrid Crosses

Dihybrid Crosses

Dihybrid Crosses. Biology 30 Mrs. S. Pipke-Painchaud. Dihybrid Crosses. the natural progression for Mendel was to study 2 characteristics at the same time. thus, the study of 2 pairs of contrasting traits at the same time = a dihybrid cross ex.. round yellow seeds X wrinkled green seeds.

Genetics of Inheritance

Genetics of Inheritance

Genetics of Inheritance. History. Gregor Mendel was a monk who did experiments on garden peas in the 1860s. Peas have many varieties and strict control over mating is possible. Mendel. Example: Mendel bred round peas and wrinkled peas. The first generation had only round peas.

Dihybrid Crosses

Dihybrid Crosses

Dihybrid Crosses. When is it used?. A dihybrid cross is exploring the possibilities of TWO traits. For example, what will the offspring look like when a yellow, wrinkled pea plant is crossed with a green, smooth pea plant. You are looking at two traits- pea color and pea texture.

Fork-line Method A method that uses genotypic ratios to predict the outcomes of genetic crosses.

Fork-line Method A method that uses genotypic ratios to predict the outcomes of genetic crosses.

Fork-line Method A method that uses genotypic ratios to predict the outcomes of genetic crosses. Based on the idea that, in a dihybrid, the two traits sort independently of one another * What happens with one trait is completely unrelated to what happens with the other trait.

Codominance

Codominance

Codominance. Codominance - a condition in which two dominant alleles are expressed at the same time. Neither allele is dominant or recessive. The alleles do not blend in the phenotype.
