How does DNA affect parent's offspring?

Answer 1

If a parent has a mutation and survives and reproduces, it's offspring will also have that genetic mutation, and over time, if the animals with the mutation survive, the whole species will have the mutation. This is called evolution.

Answer 2

Just before nuclear division chromosomes are duplicated. In the S-stage of the cell cycle, DNA is replicated and chromosomes become duplicated. A chromosome is composed of two identical parts/sister chromatids and each containing one DNA double helix molecule. The zygote and body cells have homologous pairs of chromosomes but the gametes have only one chromosome of each kind coming from either the paternal "father" or maternal "mother" homologue. No replication of DNA is needed between meiosis 1 and meiosis 2 because chromosomes are still duplicated and they already have two sister chromatids. In meiosis "a.k.a. sexual reproduction cells" two nuclear divisions are required to produce four haploid daughter cells, each having one of each kind of chromosome. In other words the daughter cells have half the number of chromosomes as their haploid parent nucleus had. Theses daughter cells receives one kind of each kind of parental chromosome but in mixed combinations and that is why daughter cells are not genetically identical to the parent cell. During meiosis 2 the sister chromatids separate to become daughter chromosome that move to opposite sides of poles. The chromosomes in the four daughter cells contain only one DNA double helix molecule because it is not duplicated.

Answer 3

In asexual reproduction, the offspring has the exact same DNA as it's parent. It is a clone. Mutations can still occur, but by definition, normal asexual reproduction, without mutations, results in offspring with identical DNA as the parent.

Answer 4

The order of the genes in your DNA (your genotype) will affect the phenotype depending on whether you're heterozygous or homozygous for a trait.

Answer 5

the mutation in the parent could affect the offspring it's whole life.the mutation could be genetic and will change the DNA in the offspring.

Answer 6

Depends on the most active dna. or the one that is ruling.

Answer 7

The parents pass along genes to the child.

Answer 8

A child inherets half of his/her genotype from each parent, if either parent has genetic disorder, it is likely to affect the child also.

Answer 9

A human's DNA carries the traits of a person. Basically, your DNA carries the genes that would pass on the traits that you have to the lineage of your generation.
