Scientists compare DNA from living organisms to identify similarities between species
Answer: Option D
<u>Explanation:</u>
The DNA content of any organism codes for its behavior and other activities, the nucleic acid is the only encryption that takes the internal code of the parents to the off springs, hence a comparison in the evolution can be done only through testing the DNA content.
The information in the DNA also tells us the evolution of species along with their relationship with each other. Thus helps in the construction of the phylogenetic tree.
Answer:
The correct answer would be A). They will all be blue.
Genotype of the parents are BB and bb.
As both are homozygous in nature so, each will produce only one type of gamete.
BB will produce gamete B and bb will produce b as its gamete.
The cross will results in the production of offspring each with genotype Bb.
We know that blue is a dominant trait and thus it will be expressed in heterozygous condition (Bb).
Hence, all offspring would be blue in color.
Putting a liquid in a freezer will turn it into a solid/ice. Boiling water will turn the water into gas. Melting an ice cube will turn into liquid because of the heat.
