I hope I helped!
Duplications are repeated segments of genetic materials that result from unequal crossing over during meiosis or through a replication error prior to meiosis. They usually occur when homologous pairs do not line up correctly or in chromosomes with a lot of repeat sequences. Duplication of a segment of a chromosome would result in Genetic variability during evolution due to gene duplication.
Answer:
Translocation
Explanation:
Changes in chromosome include deletions, duplications, inversions, and translocations.
- Deletion occurs when an end of a chromosome breaks off.
- Duplication is the presence of a chromosome segment more than once in the same chromosome.
- Translocation is when a fragment of chromosomal breakage join a nonhomologous chromosome.
- Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes.
- Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" together.
Mixture should be the answer.
The answer is B since you have to be able to prove/elaborate on the topic sentence
