20 Questions
What is the process called when genes that control certain traits are passed through generations?
heredity
How does genetic information transmission differ in simpler organisms compared to complex ones?
lower or simpler organisms reproduce via asexual reproduction and complex ones reproduce via sexual reproduction
What is the result of asexual reproduction?
progenies that are clones of their parent cells
Which type of reproduction occurs in larger multicellular organisms like humans, plants, and animals?
sexual reproduction
What are the two reproductive organs found in bisexual plants?
male (stamen) and female (ovary) reproductive organs
What is the process by which sex cells or gametes are produced?
meiosis
What is the purpose of meiosis in sexual reproduction?
The purpose of meiosis in sexual reproduction is to produce gametes or sex cells.
What is the difference between meiosis and mitosis?
Meiosis only occurs in gamete-forming cells and produces haploid cells with half the number of chromosomes, while mitosis occurs in all other types of cells and produces diploid cells with the same number of chromosomes as the parent cell.
What are the end products of meiotic cell division?
The end products of meiotic cell division are haploid cells with half the number of chromosomes.
How many chromosomes are present in human gametes?
Human gametes have 23 chromosomes.
What is the process that restores a complete diploid set of genomes in the zygote?
The process that restores a complete diploid set of genomes in the zygote is fertilization.
What are the major causes of genetic variation?
The major causes of genetic variation are DNA heritable mutation, gene flow, and sexual reproduction through meiosis and random fertilization.
What is the purpose of meiosis in creating genetically different organisms?
Meiosis facilitates the creation of genetically different organisms.
What is the significance of crossing over during meiosis?
Crossing over leads to the formation of unique combinations of genetic material.
How does the number of chromosomes in a cell affect the number of genetic combinations it can produce?
The number of chromosomes in a cell affects the number of genetic combinations it can produce through independent assortment.
Why is it highly unlikely for any two sperm or egg cells made by a person to be identical?
The process of fertilization adds an even bigger number of possible genetic combinations, making it highly unlikely for any two sperm or egg cells to be identical.
Why is genetic variation beneficial for a population?
Genetic variation provides benefit in handling changing ecological conditions better than those that do not contain genetic variation.
What is synapsis in meiosis?
Synapsis is the process of getting together and pairing of homologous chromosomes.
What is the result of crossing over during meiosis?
Crossing over leads to the rearrangement of chromosomes and the formation of chiasmata.
How does crossing over contribute to genetic variation?
Crossing over leads to the formation of unique combinations of genetic materials derived from both parents, increasing genetic variation.
