Answer 1

Answer:

1. crossing over

2. exchange of parts of of gene from one chromosome to another.

3. a chromosome is a pair of chromatid

6.

i) in metacentric the centromere at the middle and in telocentric the centromere is at an end

ii) centromere is the point of of contact between two chromatid and where is the extension of the the DNA in a chromosome

iii) maternal chromosome is the chromosome with comes from Mother and paternal chromosome is the chromosome which comes from father
