Gregor Mendel is often called the father of modern genetics for his study of inheritance in pea plants How did Mendel identify the genetic variation within the pea plants?
Mendel identified genetic variation within pea plants by crossbreeding different varieties and observing how traits were passed down through generations. He carefully controlled the pollination process to ensure accurate results and analyzed the patterns of inheritance of specific traits. Through his experiments, Mendel established the principles of heredity that laid the foundation for modern genetics.
Which postulate of natural selection is best supported by the work of Gregor Mendel?
The postulate of variation is best supported by Mendel's work. His experiments with pea plants demonstrated the presence of distinct hereditary traits that can be passed down through generations, providing evidence for the existence of genetic variation within a population.
What was Gregor Mendel's contributions to cells?
Gregor Mendel is best known for his foundational work in genetics, establishing the principles of heredity through his experiments with pea plants. While he did not directly study cells, his discoveries about how traits are inherited laid the groundwork for understanding genetic variation at the cellular level. Mendel's laws of segregation and independent assortment explain how alleles, the genetic units located within cells, are passed from one generation to the next, influencing the characteristics of organisms. His work ultimately contributed to the field of molecular biology and the study of genetic material within cells.
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.
How does standing genetic variation contribute to the overall genetic diversity within a population?
Standing genetic variation refers to the existing genetic differences within a population. This variation contributes to genetic diversity by providing a pool of different genetic traits that can be passed on to future generations. This diversity helps populations adapt to changing environments and increases their chances of survival.
What characteristic within populations causes natural to occur?
genetic variation
Does natural selection have a tendency to increase or decrease genetic variation within a population?
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
How do stabilizing and disruptive selection differ in terms of their impact on the genetic variation within a population?
Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.
Are mutations a significant source of genetic variation?
Yes, mutations are a significant source of genetic variation as they introduce new genetic changes that can lead to differences in traits among individuals within a population.
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 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.
