The chromosomal condition in Turner's syndrome is
or A human female with Turner's syndrome

Options

A. 21 Trisomy with XY
B. 44 Autosomes +XXY
C. 44 Autosomes +XYY
D. 44 Autosomes +XO

Explanation

**Step-by-Step Solution:**

1. **Understanding Turner's Syndrome**: Turner's syndrome is a genetic condition that affects females. It is characterized by the absence of one of the two X chromosomes typically found in females.

2. **Chromosomal Count**: In a normal human female, there are 46 chromosomes, which include 44 autosomes and 2 X chromosomes (XX). However, in Turner's syndrome, one of the X chromosomes is missing.

3. **Chromosomal Condition in Turner's Syndrome**: Therefore, the chromosomal condition in Turner's syndrome is 45 chromosomes in total. This includes 44 autosomes and 1 X chromosome (X0).

4. **Genotype of a Female with Turner's Syndrome**: The genotype of a human female with Turner's syndrome can be represented as 44 autosomes + 1 X chromosome + 0 (indicating the absence of the second X chromosome). Thus, the genotype is often denoted as 45,X.

5. **Final Answer**: The chromosomal condition in Turner's syndrome is 45,X (or 44 autosomes + 1 X chromosome).
