Q – 2. State whether the subsequent statements are actual or False [Marks 4.5]

1 Operation Flood scheme for milk was started at Anand.
2 Frieswal cattle is a synthetic breed.
3 Sunandini cattle has inheritance of Brown Swiss
4 CSWRI is located at Avikanagar.
5 Pandharpuri buffalo cattle breed belongs to Maharashtra.
6 The Dwarf breed of Kerala is Panganur.
7 For carcass traits Individual selection is preferred.
8 Tandem method allows selection of 2 or more traits at a time.
9 The heritability sets upper limit of repeatability.
10 Selection creates new genes.
11 The bull is considered as proven bull when his progeny's milk production is 20 percent
higher than population mean.
12 The repeatability is equal to (s2G + s2 EP) / s2 P.
13 Avikalin is synthetic breed of sheep.
14 The genetic correlation ranging from Egg weight and body weight is negative. 15 Ratio of response to selection and selection differential is realized heritability.

Q – 5. Write down most improper ans from the provided in the bracket. [Marks 4.5]

1 For carcass traits, (Individual / Pedigree / Family) selection is not preferred.
2 In Osborn index for (Pullet / Cockerel) individual's performance is not included.
3 (Artificial / Natural) Selection means permitting a few type of individuals to produce more
offspring than other types do.
4 "Survival of fittest" is Darwin's theory of (Artificial / Natural) Selection.
5 The branch of genetics that deals with study of chromosome is (Cytogenetics / Molecular
genetics / Biochemical genetics).
6 Specific combining ability of a line is due to (Dominance / Epistasis / Overdominance / all
of these) gene effect
7 Heritability in broad sense is (VA/VP ; VG/VP).
8 The mean deviation from population mean of all the genotype in to which gene enters is
called as (Average effect of gene / Genic value / Additive effect of gene / All of above)
9 Vechur is the dwarf cattle breed of (Kerala / A.P. / Karnataka).
10 s2G = s2 A + ____+_____ (s2D + s2 E ; s2 D + s2 I ; s2 D + s2 E + s2 I ).
11 For 1st cousins relationship, the covariance is _____ (1/2 s2A+1/4 s2 AA ;
1/4 s2 A+1/16 s2 AA ; 1/8 s2 A+1/64 s2 AA )
12 Lowly heritable traits are affected by (additive / non additive / both) gene action.
13 The breeding value is equal to _____ X transmitting ability (1/2 ; two ; 3)
14 The goat breed of Gujarat is (Sirohi/ Marwari/ Zalawadi)
15 The genetic correlation may be (positive / Negative / zero / all of these)
