new combinations of alleles
What else can I help you with?
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
Who gives alleles?
Organisms inherit their alleles from their parents. In sexual reproduction, the alleles are usually inherited from two parents. In asexual reproduction, the alleles are inherited from a single cell and are genetically identical to the parent.
Does fertilization create new combinations of alleles?
Yes- each gamete cell is haploid, containing half the mother or father's full set of chromosomes. when the two fuse, then a new diploid cell is created, with a full number of chromosomes- half from the mother and half from the father. It has a new genetic combination- the cells of offspring created via sexual reproduction are not genetically identical to their parents' cells.
What determines an organisms alleles in sexual reproduction?
An organism's alleles in sexual reproduction are determined by the combination of alleles inherited from its two parents. Each parent contributes one allele for each gene, leading to genetic diversity in the offspring. Random assortment and recombination of alleles during meiosis further contribute to allele variation.
What evolutionary forces could create new genetic information in a population?
Mutation, gene flow, and genetic recombination are evolutionary forces that can introduce new genetic information into a population. Mutation is the primary source of genetic variation by creating new alleles. Gene flow allows for the movement of genetic material between populations, introducing new alleles. Genetic recombination during sexual reproduction can also create new combinations of genes, increasing genetic diversity.
Which does sexual reproduction create new allels or new combinations of alleles?
new combinations of alleles
Which does sexual reproduction create new alleles or new combination of allele?
Sexual reproduction creates a new combination of alleles.
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
E What is sexual reproduction?
Sexual reproduction produces individuals with genes from two parents, which increases the combinations of alleles possible in a population. This increase in combinations of alleles can be useful when changes in the environment occur requiring new adaptations. Populations with large stores of variation can, in general, adapt better to those changes because they already have the necessary variation in place.

Three ways that alleles are recombined during sexual reproduction?
recommmbinant
How traits are inherited through alleles?
By sexual reproduction the parental alleles through gametes are inherited in the subsequent generation
Why is sexual reproduction a source of genetic variations?
When alleles are recombined during sexual reproduction, they can produce dramatically different phenotypes. Thus, sexual reproduction is a major source of variation within many population.
What is it called when gametes randomly pair to produce different combinations?
That is called genetic recombination, where different combinations of genes are created through the random pairing of gametes during sexual reproduction.
Why does sexual reproduction the genetic variation in a species?
A fertilized egg has a mixture of alleles from the two parents.
