Calculate the proportion of F1 hybrid vigour retained at equilibrium for the following rotations involving hybrid sires (assume that the breeds in each sire type are present in equal proportions). Use the equation for ‘predicting equilibrium hybrid vigour in rotational crossbreeding systems that use crossbred sires’)Three-way rotation using hybrid A x B x C x D sires; E x F x G x H sires; I x J x K x L siresTwo-way rotation using hybrid A x B x C x D x E x F x G x H sires;

In the united states there are strict fishing seasons and limits, but not all countries enforce similar laws. in bangladesh there are few if any fishing restrictions. what might be the reason for less restrictions in smaller countries like bangladesh? a) the united states is the only country worried about overfishing. b) the united states wants to limit the supply of fish to increase the price. c) bangladesh and smaller countries have an unlimited supply of fish in their coastal waters. d) small countries, such as bangladesh, are practicing subsistence fishing, taking only the fish needed to survive.

Idon’t understand this can someone give me the answer? you
