Exam 3 Flashcards
T/F
P=BV+GCV+E
True
T/F
BLUP stands for Best Linear Unbiased Prediction
True
T/F
According to information found in the Angus Sire Summary the heritability between REA and Yearling Weight is .35
False
T/F
Genetic correlation occurs when a single gene affects two traits. Genetic correlation can be positive or negative, which is indicated by assigning a number in the range from -1 to 1.00
True
T/F
Docility EPDs indicate disposition. Selecting for higher DOC EPDs would result in calmer cattle
True
T/F
Selection based on higher HP EPDs would lead to cattle with earlier sexual maturity and more fertility
True
T/F
$Beef values are based on calving ease, milk and fertility. Selecting for higher $Beef values would result in cows that earn more $ in production based on maternal performance
False
T/F
Accuracy values are reported for each EPD. Accuracy values are expected to increase when EPDs are based on more information
True
T/F
Effective cross breeding systems require purebred animals
True
T/F
BV represents the part of G that can be passed from parent to offspring
True
T/F
Breeding Value is the sum of independent additive gene effects that are transmit able to offspring
True
T/F
Only one of each gene pair can be transmitted from parent to offspring. Genes can’t be transmitted in pairs. This explains why independent gene affects but not gene combination effects are transmitted from parents to offspring
True
T/F
For a given animal a pedigree estimate EPD would be lower Accuracy as compared to the animals GE-EPD
True
T/F
A contemporary group is a group of animals raised in the same environment given the same opportunity to perform. Contemporary groups should consist of both males and females in must be born on the same day
False
T/F
Selection based on EPDs for RADG should lead to change in Feed Efficiency or more Average Daily again post weaning given a constant daily feed intake
True
