Wetland is the transition land intermediate to the the land and water body. Wetlands provide minerals and nutrient to many species of plants and animals and therefore, wetlands can help a species population to thrive. However, the wetlands have been damaged to get a great extent and there are certain challenges to restore them and they are:
i. Lack of detailed understanding of the coastal ecosystem because the shift in geographic units like lagoons, tide levels due to human activities and natural process are not examined and noted regularly.
ii. Lack of knowledge about site specific bio-morphological interactions as to how will the species react to the different type and amount of sediments in the wetland.
The black cat is the dominant allele B and the white cat is a recessive allele w. now,
in f1: the dominant allele masked the recessive characters but they are heterologous dominant ie BBww
in f2: Bw x Bw
the outcome is BB,Bw,Bw,ww
