Q. No.A plant, on repeated self pollination, preserves the trait expressed for many generations. Such a plant is said to be:
(1) Panmictic
(2) Homologous
(3) Apomictic
(4) Pure line
(1) Panmictic
(2) Homologous
(3) Apomictic
(4) Pure line
The F1 progeny in monohybrid crosses by Mendel resembled:
1. The parent exhibiting dominant trait completely
2. The parent exhibiting recessive trait completely
3. The parent exhibiting dominant trait partly
4. The parent exhibiting recessive trait partly
A test cross is done to find out:
(1) Fitness of an organism
(2) Genotype of a plant expressing dominant phenotype
(3) The suitable parents for a Mendelian Cross
(4) The hidden genotypic ratio of F2 phenotypes
The law of Segregation is based on the fact that
| 1. | The alleles do not show any blending |
| 2. | There is random fertilization |
| 3. | Gametes are pure for the trait |
| 4. | The zygotes are diploid |
The inheritance of flower colour in dog flower and 4’O clock plant exhibits:
1. Complete dominance
2. Incomplete dominance
3. Co-dominance
4. Lethality
In complete dominance, the recessive allele with respect to the dominant allele:
1. Produces no product
2. Produces a different product
3. Produces half the product
4. Produces no product or a non-functional product
The number of alleles, the genotypic combinations and phenotypes in ABO system is respectively:
(1) 3, 6 and 4
(2) 3, 4 and 6
(3) 2, 3 and 4
(4) 2, 3, and 6
Suppose a gene has seven alleles. What would be the number of alleles in an individual at any instant?
(1) 1
(2) 7
(3) 2
(4) 3
