What is traslocation
1 answer:
Answer:
The exchange of chromosome segment between non-homologous chromosomes is called translocation.
It is of two types:
- Reciprocal translocation
There is an exchange of chromosome segments between two non- homologous chromosomes in reciprocal translocation.
- Non- reciprocal translocation
A part of chromosome is translocated from one non-homologous chromosomes to other so that one chromosome becomes deficient and another non-homologous chromosome gains the piece of chromosome and becomes long.

Answer:
Option C
Explanation:
Given ,
A1 allele is carried by % people
Let us assume A1 s dominant genotype
This means
Thus, frequency of allele in the given population is
It is also given that the population is in Hardy-Weinberg equilibrium thus
Frequency of fruit fly with genotype A2A2 will be
As per Hardy-Weinberg's second equation of equilibrium
Hence, option C is correct
