Do offspring of a sexually reproducing organisms have the same genetic code as their parents?

Offspring of a sexually reproducing organism have different genetic code as their parents.

Explanation:

With sexual reproduction, offspring are genetically unique because they get a mix of genes from mom and dad. In sexual reproduction, the male and female reproductive cells are called gametes, or simply the sperm and egg. Each gamete contains half the number of chromosomes found in other cells of the organism.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
