The reason why the changing conditions challenge the survival of the organisms living in the estuaries experiencing both freshwater and saltwater conditions each day with the rising and falling of tides. Concept introduction: The species of plants, fishes and animals living in the saline conditions near the estuary adapt to the changing conditions of the climate. The plants have aerated roots for removing the salts and for the intake of gas for the metabolism inside plant cells. The fishes migrate from this region, due to the change in the climate. The sea organisms like blue crab and oyster migrate during the breeding season and the laying of eggs to the other regions to avoid the excessive salty conditions in estuaries.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
