No, he did not. The genetic aspect of life was not discovered until much later. Mendel published his groundbreaking work in 1866, but only spoke in general terms of hereditary traits. (The mechanism was not understood.) Darwin died in 1882, and the "real work" in genetics did not begin until the 20th century. Darwin's idea of the tree of life was a brilliant stroke - it was genius - but, though genetics explains the "growth" of the tree of life, Darwin did not know this.

Mutations can occur from faulty proteins damaged genes or genes that are copied incorrectly true or false?
True. You people are pissing me off, I'm trying to study here... . Way to go. Not my fault ya'll want to fail in life.
Is it true that only mutations in gametes can be passed from parent to offspring?
Gametic mutations occur in the cells of the gonads (which produce sperm and eggs) and may be inherited. There are two types of mutations that can occur in gamete cells: 1. Gene Mutations 2. Chromosomal Mutations
True or false about gene mutations are Point mutations affect just one nucleotide?
yes
Somatic mutations occur in sex chromosomes and can be inherited?
true
Is it true or false that mutations that result from the substitution of the nitrogen base for another are called deletions?
TRUE
What statement about cancer is true?
Mutations in certain genes cause tumors. Gucci.
Is it true that Study of the Hox genes indicates that it takes hundreds of mutations to lead to diversification of the basic vertebrate limb structure?
No.
Mutations can occur from faulty proteins damaged genes or genes that are copied incorrectly true or false?
True. You people are pissing me off, I'm trying to study here... . Way to go. Not my fault ya'll want to fail in life.
Where do Darwin's finches live?
All known species of Darwin's Finches are found on the Galápagos islands. With the exception of one, the Cocos Finch, which is found on the Cocos Island. Darwin's finches are not actually true finches. Darwin knew they weren't finches, but an ornithologist called Percy Lowe, later in 1936 incorrectly called them "Darwin's Finches" in a book, a term which unfortunately stuck.

Is 'mutations are beneficial to organisms' a true statement about mutations?
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Cancer is a disease of which of these genes DNA hormones?
Cancer is primarily a disease of the genes. Specifically, it is a disease characterized by abnormal changes or mutations in the DNA (deoxyribonucleic acid) of cells. These mutations can affect the normal function and regulation of genes, leading to uncontrolled cell growth and the formation of tumors. Hormones, on the other hand, can play a role in the development and progression of certain types of cancer. Hormone-related cancers, such as breast cancer and prostate cancer, are influenced by the presence and activity of hormones in the body. In these cases, hormones like estrogen and progesterone in breast cancer or testosterone in prostate cancer can stimulate the growth of cancer cells. It is important to note that while hormones can contribute to the development of specific types of cancer, the underlying cause of cancer is ultimately genetic mutations within cells. These mutations can be influenced by various factors, including environmental exposures, lifestyle choices, and inherited genetic predispositions.
Is it true that you are more than the sum of your genes?
The answer is No you are not more then your genes.
What is cancer genetics?
Many of the genes that contribute to the event of cancer comprise broad categories: Tumor suppressor genes square measure protecting genes. Normally, they limit cell growth by observation however quickly cells divide into new cells, repairing mismatched DNA, and dominant once a cell dies. once a tumour factor is mutated, cells grow uncontrollably and will eventually kind a mass known as a tumour. BRCA1, BRCA2, and p53 square measure samples of tumour suppressor genes. Germline mutations in BRCA1 or BRCA2 genes increase a woman's risk of developing hereditary breast or sex gland cancers. the foremost normally mutated cistron in folks that have cancer is p53. In fact, quite five hundredth of all cancers involve a missing or broken p53 cistron. Most p53 cistron mutations square measure nonheritable mutations. Germline p53 mutations square measure rare. Oncogenes flip a healthy cell into a cancerous cell. Mutations in these genes don't seem to be hereditary. 2 common oncogenes are: HER2, that could be a specialised macromolecule that controls cancer growth and unfold, and it's found on some cancer cells, like breast and sex gland cancer cells The ras family of genes, that create proteins concerned in cell communication pathways, cell growth, and death. DNA repair genes fix mistakes created once DNA is traced. however if someone has miscalculation in a very DNA repair cistron, these mistakes don't seem to be corrected. then they become mutations, which can eventually cause cancer. this is often very true if the mutation happens in a very tumour factor or cistron. Mutations in DNA repair genes will be hereditary, like with kill syndrome, or nonheritable. Despite all that's renowned regarding the various ways in which cancer genes work, several cancers can't be coupled to a particular cistron. Cancer probably involves multiple cistron mutations. Some proof conjointly suggests that genes move with their atmosphere, additional complicating genes' role in cancer.
