Answer 2

Answer:

• Only the kalbasu-rohu hybrid has had karyotype analyses of hybrids conducted within the species of Indian big carps.
• Although the number under each type varies, the diploid number and type in these hybrids are the same as in the parent species.
• In contrast to the parent species, the rohu-catla hybrids' karyotypes had four metacentric, 24 submetacentric, and 22 acrocentric pair divisions.
• According to Jana, the catla-rohu hybrid's karyotype consists of 16 telocentric (16+12), 28 subtelocentric (16), and 12 metacentric (12) cells.
• Khuda-Bukhsh and Manna discovered 10 metacentric, 14 submetacentric, and 26 subtelocentric telocentric chromosomes in the hybrid between L. calbasu and C. catla.

• According to Krishnaja and Rege (1975), the interspecific hybrid created by crossing L. calbasu with L. rohita had 50 diploid (2n) chromosomes.
