Answer:
1/8.
Explanation:
Karyotype may be defined as the visual appearance and the number of chromosome of the organism. Karyotype helps in studying the chromosomal abnormalites.
The human male has extra piece at chromosome 4. The abnormal pattern on the chromosome 7. The probability to inherit the defective chromosome 4 is 1/2, defective chromosome 7 is 1/2 and the probability of Y chromosome is 1/2. The probability of child to inherit all these chromosome is (1/2) × (1/2) × (1/2) = 1/8.
Thus, the answer is 1/8.
Autotroph's are living organism which produce complex compounds
