Question

How many choromosomes are there in crab ,round worm and maize​

Answer 1

Explanation:

Karyotype of a human being, showing 22 pair of autosomal chromosomes and both the XX female and the XY male possibilities for the pair of allosomic (sex) chromosome

Fusion of ancestral chromosomes left distinctive remnants of telomeres, and a vestigial centromere. As other non-human extant hominidae have 48 chromosomes it is believed that the human chromosome 2 is the end result of the merging of two chromosomes

Answer 2

Explanation:

All 10 chromosomes of maize (Zea mays, 2n = 2x = 20) were recovered as single additions to the haploid complement of oat (Avena sativa, 2n = 6x = 42) among F1 plants generated from crosses involving three different lines of maize to eight different lines of oat
