B. Colour blind
C. Carrier for Haemophilia
D. Carrier for colour blindness

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the family pedigree of Queen Victoria and what it indicates regarding her genetic condition.

2. **Identifying the Genetic Disorder**: The transcript discusses hemophilia, a genetic disorder that affects blood clotting. It is important to recognize that this disorder is inherited in a specific manner.

3. **Inheritance Pattern of Hemophilia**: Hemophilia is described as a sex-linked disorder, specifically linked to the X chromosome. In this case, the defective gene is recessive. This means that males (who have one X and one Y chromosome) are more likely to express the disorder if they inherit the affected X chromosome.

4. **Queen Victoria's Role**: The transcript indicates that Queen Victoria was a carrier of hemophilia. This means she had one normal X chromosome and one affected X chromosome. As a carrier, she would not express the disorder herself but could pass the affected gene to her offspring, particularly her sons.

5. **Criss-Cross Inheritance**: The term "criss-cross inheritance" is introduced, which explains that the disorder can be passed from mother to son. This is significant in understanding how hemophilia was transmitted in Queen Victoria's family.

6. **Conclusion**: Based on the analysis of the pedigree and the inheritance pattern, it can be concluded that Queen Victoria was a carrier of hemophilia, which explains the presence of hemophilia in her sons.

### Final Answer:
Queen Victoria was a carrier of hemophilia.
