With this x and y pair they are male
Answer:
The four bases A, T, C and G make up the genetic code. The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

It is right trust me. It needs a longer beak to reach food in smaller areas and it has adapted to the enviroment in many years
Answer:
The preferable option will be - 1.
1. The fish using ventral fins as "feet" will be present in increasing numbers.
Explanation:
After many years, the fish who are using ventral fins as "feet" will be present in increasing numbers because -
We know that
- These pools are temporary pools made up of rainwater. These pools do not last for longer times.
- Some fish have developed their ability to use their ventral fin as feet and can travel from one temporary pool to others.
- So, after many years, more and more fish will develop that ability to survive.
- As we all know about "the survival of the fittest" theory so some of them won't be able to make it.
- To develop their ventral fin as their real feet will take thousands of years and some genetic modification. So, that won't happen in many years.
