Question

sibling locke The image above are examples of zebrafish larvae. The larva in panel A ("sibling) represents a phenotypically normal zebrafish at this developmental stage. The larva in panel B has a null mutation in a gene called locke, which is unable to make motile cilia leading to many deleterious phenotypes. Based on this information, choose all of the responses that correctly describe the phenotypes observed in this image. The cross-section view shows the locke mutant appears to have a longer tail than the normal sibling. The yolk ball on the ventral side appears less pigmented in the locke mutant. From a dorsal view, the locke mutant clearly has brain abnormalities. The anterior-posterior axis exhibits unusual curvature in the locke mutant compared to the normal sibling. From the coronal view, it is clear that the mouth of the locke mutant is deformed compared to the sibling

Explanation / Answer

Answer. The conclusions drawn from the above figure are:

Zebra fish is considered to be a very vital scientific model organism for studying vertebrate development and gene function.

Wild-type organisms are used for this purpose.
