What else can I help you with?
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
What process can Genetic changes in mitosis can only occur by?
Genetic changes in mitosis can only occur through mutations, which are changes in the DNA sequence. These mutations can be caused by errors during DNA replication, exposure to mutagens like radiation or chemicals, or spontaneous changes in the DNA.
Why is the rate at which mutations occur rather slow?
Mutations occur at a relatively slow rate because cells have mechanisms in place to correct errors during DNA replication, reducing the chances of mutations. Additionally, mutations that have harmful effects on an organism's survival and reproduction are often removed from the gene pool through natural selection.
What Mutation does not affect the offsping?
Somatic mutations are not passed on to offspring because they occur in non-reproductive cells. These mutations only affect the individual in which they occur, and are not transmitted to future generations.
Which of the three stages of interphase does DNA replicate?
Interphase is only one phase of the cell cycle, which is composed of: G1, S, G2 and M phases. DNA replication occurs during the S phase of the cell cycle

How are mutations passed down from parent to offspring?
Mutations can be passed from parent to offspring only by mutations found in genes. These genetic mutations can be hereditary. Chromosomal mutations only occur in one person and cannot be passed on to the offspring.
T is not easy to observe individual chromosomes during the interphase because?
Only during the division stages of a cells life will chromosomes form. During Interphase the cells DNA is in the unorganized form of chromatin.

Interphase is only one phase of the cell cycle, which is composed of: G1, S, G2 and M phases. DNA replication occurs during the S phase of the cell cycle
How many times does DNA replicate in meiosis?
1 time only which is done during the only interphase in meiosis.
Are gamete cells mutations and somatic cells mutations inheritable?
Since only gamete cells actually participate in the creation of a new organism, it is only the mutations in gamete cells which are inheritable; mutations in somatic cells are not inheritable.
When do chromosomes replicate during meiosis?
Chromosomes replicate during the S phase of interphase, before meiosis begins. This ensures that each chromosome consists of two sister chromatids, which are then separated during the meiotic divisions to produce haploid cells.
Can you see individual chromosomes during interphase?
Chromosomes during interphase only have one chromatinFound this answer while doing a crossword for my bio 101 class, it fits in the space - if that helps your confidence in my answer
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
