Using the Punnett square determine the phenotypes and genotypes of the offspring.
A black angus male BB is crossed with a red angus female bb. determine the genotype and phenotypes of their offspring. (black is dominate/ red is recessive)
Genotype: 100% Bb
Phenotype: 100% Black
Who is the father of genetics?
Gregor Mendel
The Phenotype focuses on what?
The genetic makeup/ allele or the physical trait passed on.
The physical trait

The top stripe of the U.S. flag is red or white?
Red
This genetic sequence is single stranded, and transfers DNA messages to the rest of the cell.
RNA
When reading an EPD we want the birth weight to be a high number. True or False? Why?
False! High birth weights cause birthing problems
Define Selective Breeding
process by which humans use animal breeding to selectively develop particular phenotypic traits by choosing which female and male animals will reproduce to have offspring

Earth is the _____________ planet from the sun.
Using the Punnett square determine the phenotypes and genotypes of the offspring.
A Heterozygous yellow Charolais bull is crossed with a Homozygous white Charolais female. (Yellow is dominant/ white is recessive)
Genotype: 50% Yy, 50% yy
Phenotype: 50% Yellow, 50% White
When reading an EPD for Ewes, it is better for a Ewe to birth and rear twins, than it is for her to birth and rear a single. Ture or False? Why?
True! When Ewes rear more than one lamb at a time they are more prolific.
Expected Progeny Difference, a predication of the between the average performance of future progeny for a given trait, used as an accurate means of assessing the genetic value of an animal.

I am a double helix sequence that has a code of every trait, and is made up of genetic material in every cell in an animal.

When reading an EPD for swine Days to 250 should be a high number. True or False? Why?
False! We want our swine to be easy feeders, the less days it takes to get to 250 the better!
Define Inbreeding
Breed from closely related people or animals, especially over many generations
