It is likely lethocreus chromosome polymorphism might occur in L. The mode of orientation and segregation of a trivalent. Powered by the open source Biodiversity Informatics Platform. Infants Children Teenagers 20s 30s 40s 50s 60s Older. The presence of an m-chromosome bivalent behaving differently from the rule was reported in some species Nokkala and Nokkala ; Nokkala ; Suja This family, although containing only about species, includes the largest bugs in the order: Nature Publishing Company, Indianapolis, Indiana.

With this staining procedure, all obtained bivalents seemed smaller than those obtained with other stain- ing procedures. Giant water bugs feed on insects, salamanders, tadpoles, snails, and even small fishes. The behavior of neoXY chromosomes differed from that of the sex chromosome of other systems because lethocetus sex chromosomes, neo-X and neo-Y, formed lethoceris bivalent at prophase I, while the sex chromosomes of other systems formed univalents.

Type A cells with no univalent were the typical chromosome pattern of testicular cells of L. However, the chromosomal behavior during spermatogenesis of the Lethocerus species has not been described, except the chromosome formula, because the cytogenetics of most species were studied during and letbocerus, and the original papers are difficult to access Papeschi and Bidau ; Papeschi and Bressa In addition, this report presents clear evidence about the existence of m-chromosomes in Belostomatidae.
