Genetic mutations are changes in the DNA sequence that can occur due to various factors, including environmental influences or errors during DNA replication. These mutations can be harmless, beneficial, or harmful, potentially leading to genetic disorders, increased susceptibility to diseases, or variations in physical traits. In human offspring, the effects of mutations can range from no noticeable impact to serious health conditions, depending on the nature of the mutation and whether it is inherited from one or both parents. Overall, genetic mutations play a significant role in human evolution and diversity.
Human limb mutations can be either dominant or recessive, depending on the specific gene involved. Typically, mutations that cause limb abnormalities are rare and can be caused by mutations in either dominant or recessive genes. Dominant mutations require only one copy of the mutated gene to be expressed, while recessive mutations require both copies to be mutated for the trait to be expressed.
Yes, mutations can be passed along to human offspring through both meiosis and mitosis. Mutations that occur in the germ cells during meiosis can be passed on to offspring, while mutations that occur in somatic cells during mitosis can potentially lead to a mosaic pattern of mutated and normal cells in an individual.

Every time a human cell divides, approximately 30 to 100 mutations can occur in the DNA due to errors in replication and environmental factors. However, most of these mutations are corrected by cellular repair mechanisms. It's important to note that while mutations are common, the majority do not lead to significant changes in cell function or contribute to disease.
Some of the effects on the human body from a nuclear explosion are death (from thermal energy/blast effects or super lethal radiation exposure), infertility and blood disorders.

Nuclear radiation can cause genetic mutations in our DNA, which can cause cancers. If the genetic mutations occur in the germ cells, then our gametes (sperm and egg cells) could have genetic mutations that could be passed on to our offspring. Also, if radiation levels are high enough, people can get radiation sickness, which can be fatal.

Because it is.
The curious thing about any type of genetic mutation is that it can change anything in any place on the affected chromosome. Most genetic mutations have no affect on the phenotype. In some extreme cases though (i.e. LOTS of radiation) offspring are known to have extensive genetic mutation.

Human limb mutations can be either dominant or recessive, depending on the specific gene involved. Typically, mutations that cause limb abnormalities are rare and can be caused by mutations in either dominant or recessive genes. Dominant mutations require only one copy of the mutated gene to be expressed, while recessive mutations require both copies to be mutated for the trait to be expressed.
Exposure to radiation can damage cells in the body, leading to health problems such as radiation sickness, cancer, and genetic mutations. The severity of the effects depends on the dose and duration of exposure.
They are lethal chromosomal mutations.
