Answer:

Mutation, fertilization, meiosis are different mechanisms by which changes can occur in the genome.

Explanation:

There are several process which is responsible for causing change in the genome of the species which results in the evolution of that species. Some of these processes are:

1. Mutation: In mutation, some nucleotide sequences get change and this change can occur due to frameshift, addition, deletion or any other process. This change in nucleotide can be seen in phenotype and helps in the evolution of the species.

2. Fertilization: During fertilization mixing of the genome of two individual takes place which results in producing a genetically distinct offspring which contains variation. So as the offspring is genetically different it can contain new alleles that can help the individual to survive in the changing environment.

 2. Having sickled red blood cells lead to the symptoms like having pain in the chest and the throbbing of her leg.

in pea plants, purple flowers (p) are dominant over white flowers (p). Show the cross between two heterozygous plants
Ostrovityanka [42]

Answer:

       <em>P      p</em>

<em>P</em>    PP   Pp

<em>p    </em>Pp    pp

PP=Homozygous purple

Pp= heterozygous purple

pp=homozygous White

Explanation:

I tried to type out the cross. The bold letters are the heterozygous  plants that you are crossing. and the normal letters are the offspring of the two heterozygous parents being crossed. Heterozygous means they are different alleles. Homosygous means the same alleles are present.

heterozygous= Pp

Homozygous= PP or pp

I hope this was the answer you were looking for!
