nope although he made various observations about it :)

Is it true Darwin knew all about genes and mutations?
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.
What a is mutation?
A mutation is simply a change in your genes or DNA sequence. The types of mutations in Biology are: substitution, insertion, deletion, and frame-shift. Contrary to popular belief, mutations are often harmless.
What is the original source of all the different alleles of a genes?
A mutation in a pre-existing gene. If the mutation effects the phenotype derived from the gene, it is determined to be a different allele. Mutations can be small (such as a single nucleotide polymorphism) or large (such as entire genome duplication).
Do scientist know all the location of genes?
No
Are all mutations bad.?
No not all mutations are bad there are good mutations and bad mutations
What does het mean in snakes?
It means 'Heterozygous' - Put simply, it means a snake carries the genes of two possible 'mutations' and it's offspring can develop either of the traits.
Cancer can occur when what mutate?
Cancer can occur when genes mutate. Genes are sections of DNA that carry instructions to make proteins. Proteins control how cells grow and multiply. When genes mutate, they can cause abnormal or missing proteins, which can disrupt the normal functioning of cells and lead to uncontrolled growth. Mutations can be very small, affecting only a few nucleotides, or very large, affecting whole chromosomes. Mutations can also be inherited from parents or acquired during a person’s lifetime due to environmental factors, such as chemicals, radiation, or viruses. Not all mutations cause cancer, and not all cancers are caused by mutations. Some cancers are caused by epigenetic changes, which affect how genes are turned on or off without changing the DNA sequence. Some people may also have a higher risk of developing cancer due to their genetic makeup, family history, or lifestyle factors
Do your genes determine all your traits?
yup we are made up of chromosomes from both our parents, however environmental factors (sun, chemicals..etc) can cause mutations in genes which alter your genetic make up eg, you get cancer, tanning (cells in trauma) etc...
Are all mutations generic?
Yes. All mutations of the genetic material are genetic.
Why dont all mutations cause cancer?
Mutations in the DNA can cause cancer, but it's not the only cause of cancer. Did you know you can get cancer if you are exposed to coals and tars too long?
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.
What is the mutated gene of the Charcot-Marie-Tooth disease?
CMT is caused by mutations in genes that produce proteins involved in the structure and function of either the peripheral nerve axon or the myelin sheath. Although different proteins are abnormal in different forms of CMT disease, all of the mutations affect the normal function of the peripheral nerves. The gene mutations in CMT disease are usually inherited.
