∙ 12y agoThrough the selective cross-breeding of 28,000+ common pea plants over many generations between 1856 and 1863, Mendel discovered that certain traits show up in offspring without any blending of parent characteristics. For instance, the pea flowers are either purple or white.

How can genes be altered and combined to create genetic variation within a species?
Through different types of mutations.ChromosomalinsertiondeletiontranslocationinversionGenesubstitutioninsertiondeletion
What process during meiosis leads to genetic variation?
DNA organizes into chromosomes within the nucleus
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.

What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What characteristic within populations causes natural to occur?
genetic variation
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
Which is an activity that increases the genetic variation within a population of earthworms?
sexual reproduction
How does variation within a species bring about evolutionary change need specific example that also mentions genetic variation and environmental conditions?
yes
What is the goal of comparative genomic studies?
to study genetic variation within a species or a populationto identify genes that are important for evolution of a particular speciesto study how genomes evolveto identify homologues in model organisms for genes involved in human diseaseAll of the above are goals of comparative genomic studies.

What process during meiosis leads to genetic variation?

Why is genetic variation importmant?
Because it yields variation of characteristics within the population, allowing for the most fit individuals (those who can best survive and reproduce) to prosper.
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
