Question

12 multiple choice 1 point with which of the following combinations could we see complementation on mv plates? ha1/ha1 ha1/hb1 ha1/hb2 ha2/hb2

Explanation:

Complementation in genetics (relevant to Biology, a subfield of Natural Science) occurs when two different mutant strains (with mutations in different genes) are combined, and the wild - type function is restored. For complementation to be seen, the two strains should have mutations in different genes.

• For the combination HA1/HA1: Both are the same mutant (same gene mutation), so no complementation.
• For HA1/HB1: If HA1 and HB1 are mutations in different genes, but we need to consider the typical complementation scenarios. However, looking at the other options, HA1/HB2 is a more likely candidate for complementation as HA1 (mutation in one gene) and HB2 (mutation in another gene) would allow for the restoration of function when combined, unlike same - gene mutant combinations (HA1/HA1, HA2/HB2) or potentially same - pathway/same - gene - related combinations (HA1/HB1 might be in the same pathway or same gene family).
• For HA2/HB2: Both are the same type of mutant (likely same gene or same pathway mutation), so no complementation.

So the combination where complementation is seen is HA1/HB2.

Answer:

HA1/HB2
