B. 2968 and 231
C. 3200 and 2500
D. 1300 and 1800

Answer

To solve the question regarding the number of genes found in chromosome 1 and the Y-chromosome of human beings, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Human Genome Structure**:
- The human genome consists of 46 chromosomes, which include 22 pairs of autosomes and 1 pair of sex chromosomes (X and Y).

2. **Identify the Chromosomes in Question**:
- The question specifically asks about chromosome 1 and the Y-chromosome.

3. **Research the Number of Genes**:
- Chromosome 1 is known to have the highest number of genes among all human chromosomes.
- The Y-chromosome, on the other hand, has significantly fewer genes compared to other chromosomes.

4. **Find the Exact Numbers**:
- According to genomic studies, chromosome 1 contains approximately **2,968 genes**.
- The Y-chromosome contains about **231 genes**.

5. **Present the Final Answer**:
- Therefore, the number of genes found in chromosome 1 and the Y-chromosome of human beings are **2,968** and **231**, respectively.

### Final Answer:
The number of genes found in chromosome 1 and Y-chromosome of human beings are **2,968** and **231** respectively.
