What changes occur in the genes of sex cells?
In sex cells, or gametes, genetic changes occur primarily through two processes: meiosis and genetic recombination. During meiosis, homologous chromosomes undergo crossing over, leading to the exchange of genetic material between them, which creates genetic diversity. Additionally, mutations can occur in the DNA of sex cells, which may be passed on to offspring. These changes contribute to the genetic variation essential for evolution and adaptation.
What causes between 80 percent to 90 percent of cancers?
1) Genetic predisposition to cancers 2) Dietary intake of foods, toxins, and chemicals leading to cellular/genetic damage or activating oncogenes or hindering cancer suppression genes 3) Environmental influences of toxins, chemicals, and radiation (all responsible for cellular/genetic damage...again, leading to activation of oncogenes or hindering of cancer suppression genes
What has the author Phyllis Guinivan written?

What are genetic changes?
Genetic changes are alterations in the DNA sequence of an organism. These changes can result from mutations, which are permanent changes in the DNA, or from genetic recombination, where genetic material is exchanged between organisms. Genetic changes can lead to variations in traits, evolution, and genetic disorders.
Which phenotypic change in genetic?
Changes that are genetic
What events may have lead to genetic changes over time?
Mutation can lead to genetic changes over time!
What are genetic materials that cause cancer?
Abnormalities of the genetic materials are the only known cause of cancer. Errors in DNA replication and heritability of the genetic diseases are the cause of cancer during birth stage. Excessive ultraviolet radiation, any harmful infectious agents, tobacco smokes or chemicals are responsible for the abnormalities of genetic materials. Genes which promote cancer are called oncogenes. They are activated in cancer Cells. Tumor suppressive genes are not activated in the cancer Cells. For that reason programmed cell death and hyper active division and growth of Cells cannot be prevented. Inaccurate DNA replication, irregular Cell cycle, damaging the immune system are the major symptoms of cancer.
