Q. No.The family pedigree of Queen Victoria shows a number of haemophilic descendants as she was:
1.
Affected by the disease
2.
Carrier for the disease
3.
Did not carry the allele for hemophilia
4.
Was not a queen
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 |
Haemophilia is inherited as a/an __________ condition.
| 1. | Autosomal recessive | 2. | Autosomal dominant |
| 3. | Sex linked recessive | 4. | Sexlinked dominant |
A genetic cross between homozygous individuals but with different alleles for a single gene of interest is called as:
| 1. | A reciprocal cross | 2. | Monohybrid cross |
| 3. | Dihybrid cross | 4. | Test cross |
What can the possible blood groups of progeny whose father and mother are of A and B blood groups, respectively?
| 1. | A and B only | 2. | AB only |
| 3. | All except O | 4. | A, B, AB, and O |
If individuals of genotype AaBbCc are intercrossed, how many different phenotypes can appear in their offspring?
| 1. | 3 | 2. | 6 |
| 3. | 8 | 4. | 9 |
The inheritance of the trait shown in the given pedigree most likely is:
| 1. | Autosomal recessive | 2. | Autosomal dominant |
| 3. | Sex-linked recessive | 4. | Sex-linked dominant |
Consider three genes: X, Y, and Z. The recombination frequency between X-Y, X-Z, and Y-Z gene pairs was found to be 50%, 25%, and 50%, respectively. What would be the right inference?
| 1. | genes X and Y are on the same chromosome |
| 2. | genes X and Z are on different chromosomes |
| 3. | genes Y and Z are on different chromosomes |
| 4. | All three genes are located on the same chromosome |
