Sardar Krushinagar Dantiwada Agricultural Uiversity 2011 Bachelor of Veterinary Science & Animal-Husbandary Semester End Practical -exam question paper
Semester End Internal Practical examination
PRINCIPLES OF GENETICS AND POPULATION GENETICS
(AGB-121: 2+1=3) Marks: 20.00
Q. 1. Write chromosome numbers obtained in liver cells of Riverine Buffalo, Mule,
Dog, Drosophila and Pig. (1.5)
Q. 2. In snapdragon, flower colour is determined by a pair of factors in such a way that
RR, Rr and rr genotypes produce red, pink and white flowers, respectively. 2
pink flower plants were self fertilized.
a) Give genotypic and phenotypic ratio in progeny plants.
b) If pink flower plants are test croseed, provide expected phenotypic proportion in
the progeny.
(2.0)
Q. 3. Under assumption of complete dominance for all gene pairs, ans the ques.
for Aa bb CC Dd Ee x Aa BB cc Dd Ee cross.
a) No. of various kinds of gametes produced by every parent.
b) Proportion of progenies expressing all dominant traits.
c) Proportion of progenies which breed true? (3.0)
Q. 4. Determine the genotypes of the parents, when rose combed male crossed with a pea
combed female produces 6 walnuts combed and 5 rose combed offspring. (2.0)
Q. 5. A fully heterozygous gray bodied and normal winged female F1 generation fruit
fly, when crossed with black bodied and vestigial winged male, the proportion of
the offsprings in various classes was as follows:
Gray normal – 13, Gray vestigial- 117, Black normal- 104, Black vestigial - 16
Do these 2 gene pairs assort independently? If not, obtain out the reason for the
identical. (Black body and vestigial wing are recessive characters). (4.0)
Q. 6. A bald man whose dad was non bald marries a non bald women whose mother
was bald. If they have two sons and one daughter what will be expression of character in
their children? Also assign the genotype of all the persons in picture. (2.0)
Q. 7. Practical Record (1.5)
Q. 8. Viva voce (4.0)

PRINCIPLES OF GENETICS AND POPULATION GENETICS
(AGB-121: 2+1=3)
Marks: 20.00
Q. 1. Write chromosome
numbers found in liver cells of Riverine Buffalo, Mule,
Dog, Drosophila and Pig.
(1.5)
Q. 2. In snapdragon, flower
colour is determined by a pair of factors in such a way that
RR, Rr and rr genotypes produce red, pink and white flowers,
respectively. Two
pink flower plants were self fertilized.
a)Give genotypic and phenotypic ratio in progeny plants.
b) If
pink flower plants are test croseed, give expected phenotypic proportion in
the progeny. (2.0)
Q. 3. Under assumption of
complete dominance for all gene pairs, answer the questions
for Aa bb CC Dd Ee x Aa BB cc Dd Ee cross.
a)No. of different types of gametes produced by each parent.
b) Proportion of progenies expressing all dominant traits.
c)Proportion of progenies which breed true? (3.0)
Q. 4. Determine the
genotypes of the parents, when rose combed male crossed with a pea
combed female produces six walnuts combed and five rose combed
offspring. (2.0)
Q. 5. A fully heterozygous
gray bodied and normal winged female F1 generation fruit
fly, when crossed with black bodied and vestigial winged male, the
proportion of
the offsprings in different classes was as follows:
Gray normal 13, Gray vestigial- 117, Black normal- 104, Black vestigial - 16
Do these two gene pairs
assort independently? If not, find out the cause for the
same. (Black body and vestigial wing are recessive
characters). (4.0)
Q. 6. A bald man whose
father was non bald marries a non bald women whose mother
was bald. If they have 2 sons and 1 daughter what will be expression
of character in
their children? Also assign the genotype of all the persons in
picture. (2.0)
