ANSC 1401 Final -Sam Jackson-Test
Questions All Solved.
effect on selection process - Answer more offspring is greater opportunity for genetic
improvement
heterosis - Answer an increase in the performance of hybrids over the average performance of
the parents
animal breeding industry structure - Answer seedstock -----> commercial----> animal products
---> commercial----> seedstock
genetic application rules - Answer 1. crossbred animals tend to preform better than their non-
related purebreds; and non related purebreds tend to preform better than inbred purebreds
2. animals tend to resemble their parents and close relatives
generation interval - Answer the average age of the parents when offspring are born or the
time required to replace a generation
genetic tools - Answer technologies which can increase the contribution of genetics from a
superior animal beyond their normal lifetime capacity
inbreeding - Answer the mating of relatives which results in increasing the number of
homozygous gene combinations
cross breeding - Answer the mating of different breeds results in increasing the number of
heterozygous gene combinations (heterosis)
factors influencing reproduction - Answer A. physiology of the animal
B. genetic potential
C. nutrition
D. season of the year
E. other environmental factors
species differences - Answer management, environment, and goals, vary by species
