Seismic waves help scientists understand Earth's layers by:
- Scientists can observe how seismic waves change speeds when passing through different layers.
- Scientists can observe which seismic waves cannot pass through certain layers.
<h3>What are Seismic waves?</h3>
These are waves which are generated as a result of the movement of 
materials in the earth. They change speed as a result of the collision with 
materials in the earth and know the types of material present as a result of 
some types not being able to pass through certain medium.

<h3>What is True breeding?</h3>
Organisms with homozygous genes are referred to as true breeders in genetics. This indicates that both alleles are identical, making PP or TT preferable to Pp or Tt. All offspring produced from the union of true breeding organisms will share the same phenotypic as their parents.
<h3>What is true breeding in Punnett Square?</h3>
Both alleles of a gene are the same in genuine breeding strains. Due to the presence of just one type of allele, crossing two plants from the same strain will result in offspring with the same genotype and phenotype as their parents.
