Why are the offspring of the same two parents genetically different?
Wiki User
∙ 10y ago
offspring from one is asexual and from two is sexual
you can look this up on Google so stop being lazy
also...
offspring from one is identical to the parent
offspring from two is different because the sperm contains DNA and so does the egg and the DNA mix to form new DNA that combines male (sperm) and female (egg) DNA

∙ 12y agoWhen a offspring is produced from one parent, it is asexual reproduction. Many bacteria and other micro-organisms can produce asexually

∙ 10y agoDue to crossing over variability in gametes is produced and on random mating of these gametes, genetic variability among offsprings of the same parents is created.

Why are offspring from the same parents not identical?
If the children have both inherited genes from the same parents, you would expect them to look quite similar. But they do not look exactly the same. Each child has inherited different genes from its father, and different genes from its mother, to create a new combination of genes. Each child is a unique person, not exactly like its brothers or sisters, but not completely different either.
Why does sexual reproduction result in more genetic variation in a species than asexual reproduction?
In asexual reproduction there are 2 daughter cells produced that are identical to the parent cell. In sexual reproduction there are 4 genetically different daughter cells produced that are haploid (23 chromosomes). Crossing over occurs during meiosis which mixes up segments of DNA on homologous chromosomes causing new genetic variations. By the sperm fertilizing the egg, you are combining 2 completely different sets of different haploid DNA to produce a diploid offspring which is genetically different from both parents.
Which breeding method results in the production of offspring with the same genotype as the parents?
vegetative propagation
The process of meiosis produces?
Two Haploid Cells.
In the cross BB x bb the percent of offspring in the F1 generation that will have the same genotype as their parents is?
answer is 0%
Will any offspring of a yeast cell be genetically different from the parents cell?
No, yeast cells should be the same not genetically different. They use asexual reproduction. Yeast cells use budding, where a cell will grow a bud, a daughter cell and it splits in two. The bud or daughter cell splits off.
What do you call a group of offspring who have the same parents?
Offspring who have the same parents are called siblings.
What produces offspring's that are similar to parents?
all organisms can divide to produce same offspring that are similar to the parents
What produces offspring that are similar to the parents?
all organisms can divide to produce same offspring that are similar to the parents
Can you tell how many different types of offspring can be borne by the same human parents?
703,68,744,177,664. This is the answer. Please tell how I calculated it.
5 How do the chromosomes of an offspring produced by sexual reproduction compare with the chromosomes of its parents?
it has some of the same and some different
What happens when breeders cross two genetically identical organisms?
When breeders cross two genetically identical organisms the same genes have an increased chance of expressing themselves in the offspring. However, the offspring will also have genes from ancestors.
How are inbreeding and hybridization the same?
Inbreeding is the breeding of closely related individuals of a species generally to produce more uniform offspring. Hybridization is the breeding of different varieties (breeds) or even different species to increase variation/ vigor in the genetic population. An example of variety hybridization would Labradoodles (labrador X poodle). An example of species hybridization would be (wolf X coyote). Many offspring produced from species hybridization are sterile... depending on the chromosome number compatibility and other factors.
What is the percentage of the possible types of offspring had the same genotype as the parents?
Since there is no information on the genetic make up of the parents only a generalized set of answerscan be given.The chance of an offspring being genetically identical in every way to either or both of its parents is virtually nil.The percentages of individuals that match the genetics of the parents for a few traits can be determined through the use of a punnet square.For example considering a single trait where one parent is homozygous dominant and the other is homozygous recessive zero offspring will have the genotype of either parent.If the parents are heterozygous for a single trait 50% of the offspring will have the genotype of the parents for that trait.The more gene pairs considered the less likely an offspring identical to the parents is possible.
What is the meaning of true breeding?
A true breeding plant is genetically homozygous. It produces the same type of plants on self fertilization. These plants are very useful for creating hybrids.
What is it called when one parent produces offspring that is an exact copy of the parent?
it is called chlorobiastic which means the offspring looks exactly like its parent.
Percentage of types of offspring had the same phenotype as the parents?
75%
