The photograph shows a mother and baby Malayan tapir (Tapirus indicus). They live in the rainforests of southeast Asia. Each gamete of a Malayan tapir contains 26 chromosomes. © Sipa US / Alamy Stock Photo The map shows the change in distribution of the Malayan tapir over the past 20 years. ................................................................................................................................................................................................................................................................................ ................................................................................................................................................................................................................................................................................ ................................................................................................................................................................................................................................................................................ (ii) One difference is that the distribution has reduced due to human activity. Suggest one reason why human activity has caused this change in distribution.

A study suggested that the genetic diversity of the Malayan tapirs has decreased due to populations being separated from each other. Explain how a captive breeding programme could maintain the genetic diversity of Malayan tapir populations.

Answer:

- still found in \{the same countries / area / region / islands / Thailand / Sumatra / Malaysia\} (1)
An answer that makes reference to the following point:
- reason as to why human activity changed distribution (1)
An explanation that makes reference to three of the following points:
- analyse \{individual's alleles / gene pool\} / identify individuals with different alleles (1)
- use a stud book (1)
- breed \{individuals / tapirs\} \{with different alleles / from different populations\} (1)
- (therefore) preventing loss of alleles (from gene pool) (1)
