Question

the odd skipped gene in drosophila received its name because mutations in that gene often lead to embryos missing the odd-numbered segments. based on this information, what is the most likely class of gene to which odd skipped would belong?

Answer 1

Step-by-step explanation:

Based on the information provided, the most likely class of gene to which odd skipped would belong is a segmentation gene.

Segmentation genes are involved in the development of body segments in organisms, and mutations in these genes can lead to defects in segmentation patterns. In Drosophila, there are three classes of segmentation genes: gap genes, pair-rule genes, and segment polarity genes.

Gap genes are involved in establishing broad regions of the body plan, while pair-rule genes define segmental boundaries and segmental periodicity. Segment polarity genes are involved in determining the polarity of segments and specifying the identity of individual segments.

Odd skipped is a pair-rule gene, and mutations in this gene often result in embryos missing every other segment along the anterior-posterior axis, leading to a segmentation defect in the developing fly. Therefore, based on its function and the phenotype associated with its mutation, Odd skipped is most likely a pair-rule gene involved in segmental patterning during Drosophila development.
