Genes provide crucial insights into an organism's evolutionary history by revealing the genetic similarities and differences between species. By comparing DNA sequences, scientists can trace lineages, identify common ancestors, and estimate the time of divergence between species. Additionally, genetic variations and mutations can indicate how organisms have adapted to their environments over time. Overall, the study of genes helps reconstruct the evolutionary tree of life, illustrating how species have evolved and diversified.
Similarities in amino acid sequences tell us the the genes coding for these proteins are similar. Similar genes are due to shared ancestry ie the organisms have evolved from a common ancestor in the past. Differences in amino acid sequence tell us that mutations have occurred in the genes since the organisms separated from the common ancestor. The bigger the differences, the longer the organisms have been separated.
The minimum number of genes needed by a living cell can vary depending on the organism. Some simple bacteria can survive with around 200-300 genes, while more complex organisms like humans have around 20,000-25,000 genes. Generally, these genes are necessary to provide the essential functions for the cell to survive and replicate.
A genotype can tell what genes you have in your chromosomes. Genotypes really means what are all your genes and phenotype is what you see. You may have brown eyes. Your genotype might show that you have brown and blue genes for eye color but you see only brown.
A scientific name can indicate the organism's genus, species, and evolutionary relationships with other organisms. It provides a standardized way to identify and communicate information about the organism in the scientific community.
Biochemistry is used to determine evolutionary relationships by comparing the sequences of biomolecules like DNA, RNA, and proteins from different species. By analyzing the similarities and differences in these sequences, scientists can infer how closely related different organisms are and construct evolutionary trees to show the relationships between them. This helps in understanding the common ancestry and divergence of species over time.

i don't no..! can anyone tell me what's the right answer...!!
2.Scientists can tell whether organisms are closely related by comparing their ____.(1 point)DNA, I had this on my test too and I answered DNA and got it right.
Cladograms tell you which animals are the closet in relationship, which are the farthest, what characteristics the animals have in common, what characteristics they would need to have in order to be closely related to them, and the number of shared characteristics between the animals.
That those organisms that posses this gene have the same common ancestor that they all branched from and developed from.
Genetics tell the story of the biological makeup of human life. DNA is composed of thousands of genes and is the backbone of human life. These genes are what composes the biological structure of all living organisms.
Genes tell cells how to make proteins.

There is DNA.
It tells you their description.

It dependes on the genes of the parent if you have no information of the genes of the parent I cannot tell you
