recessive allele
the overpowered allele
25
Codominance
where both of the alleles are represented equally and appear together
26
Homozygous
both the alleles are the same. Can Be dominant or recessive EX: BB or bb
27
Heterozygous
There is one dominant and one recessive allele EX: Bb
28
Genotype
the genetic ratio (a result of punnet square) That represents the genetic makeup of the off spring EX: 1BB, 2Bb, 1bb
29
Phenotype
The physical ratio (a result of the Punnett square) that represents the appearance of the offspring EX: 2:1 (black:red)
30
What is inbreeding?
1/2 mating systems mating of animals more closely related than the average of the breed or population
31
what is outbreeding?
1/2 mating systems mating of animals not as closely related as the average of the population.
32
What is linebreeding?
a form of inbreeding inbreeding is kept relatively low while maintaining a high genetic relationship to an ancestor or line of ancestors.
32
what is outcrossing?
mating of unrelated animals within the same breed. a type of outbreeding
33
In swine, how long does it take to get to butcher weight?
280 days
33
When was the 1st sire summary published?
1971
34
What does Flushing mean in Sheep, goats and hogs?
providing the female with excess food to falsify a good environment so that the animal would produce more eggs. This is leading up to the breeding season
35
How long is the gestation period in a cow?
284 DAYS
36
advantages of AI
1. Superior genetics 2. disease control 3. reduces potential injury 4. provides early detection of reduced semen quality
37
Disadvantages of AI
1. requires extensive management 2. Requires skill and/or training 3. cost can be expensive (materials)
38
Where is the egg shell produced in poultry?
uterus
39
What is progesterone and what does it do?
progesterone is a hormone, and it maintains pregnancy in the uterus
40
what is mitosis?
each parent cell divides into two identical daughter cells each carrying a full chromosome complement.
41
what is meiosis?
the creation of daughter cells that carry one-half the normal number of chromosomes so that during fertilization each parent has contributed a sample one-half of their genetic material to the offspring.
42
What hormone is produced in the hypothalamus?
Gonadotropin-releasing hormone (GnRH)
43
What two hormones are produced in the anterior pituitary?
Follicle-stimulating hormone (FSH) Luteinizing hormone (LH)
44
What hormone is produced in the ovarian follicle?
Estrogen
45
What hormone is produced in the corpus luteum?
progesterone
46
What hormone is produced in a non-pregnant uterus?
Prostaglandin F2alpha (PGF2alpha)
47
What hormone is produced in the posterior pituitary?
Oxytocin
48
What is hybrid Vigor?
greater vigor or productivity of crossbreds
49
what influences puberty?
early onset
50
What does a high heritability estimate mean?
Genetics plays a bigger role in this trait ex: coat color, carcass traits
51
What does a low heritability estimate mean?
Environment plays a bigger role in this trait ex: Reproduction, calving interval, etc
52
what are some EPDs?
Weining weight, yearling weight, calving ease score, ribeye area score, marbling score, milk score
53
Give me an example of EPD in action
if the selected bull has a calf, the Birth weight is +5 of the breed average. meaning the calf would be 5 pounds heavier.
54
What is the definition of Expected Progeny difference?
How we can expect the offspring to perform compared to the breed average
55
What is the correct order of anatomical structures internal to external (Female)?
Ovary, Oviduct, uterus, cervix, vagina
