What else can I help you with?
Which of the following is least likely to be a source of genetic variation among living organisms?
Things that kill the organism, such as, immature lungs at birth.
What are 4 ways in which genetic variation is created in living systems?
1. Random mating 2. a large population 3. Individuals are able to migrate to different regions 4. An absense of mutation
What is genetic?
Genetics is the study of heredity and the variation in organisms. When studying genetics, you learn about dominant and recessive traits along with much more.
Do beans have genetic material?
anything that was once living has genetic material
A form of genetic material that invades living cells to reproduce?
Virus
What are the two types of variation shown by living organisms?
The two types of variation shown by living organisms are genetic variation, which is differences in DNA sequences among individuals, and phenotypic variation, which refers to observable traits or characteristics that vary among individuals.
What are the sources of genetic variability in living organisms?
mrs gren :P
What are three sources of genetic variability in living things?
1- reproduce 2- consume 3- die
What is the ultimate source of genetic variation and the basis for the diversity of life on earth?
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
What are the two main sources of genetic information?
The two main sources of genetic information are DNA and RNA. DNA carries the genetic instructions for all living organisms, and RNA helps in the process of translating these instructions into proteins.
What is the significance of the process of crossing over to in living things?
The process of crossing over is significant in living things as it leads to genetic diversity by shuffling genetic material between homologous chromosomes during meiosis. This genetic variation increases the chances of survival and evolution by allowing for the generation of new combinations of genes.
Discuss the causes of variation Living organisms?
Causes of variation is random mutation. Random mutations constantly occur in the genomes of organisms; these mutations create genetic variation. If all living things were same, we will all use up one type of food as our nutrient source and eventually we will run out of food to consume.. making less likely for us to survive..
Which of the following is least likely to be a source of genetic variation among living organisms?
Things that kill the organism, such as, immature lungs at birth.
What is the study of heredity called?
The study of heredity is called cells
What is a variation that can help an organism survive?
A "variation" is a genetic feature expressed in some physical, physio chemical or behavioral manner by a living organism that is not present in the general population of the species to which that living organism belongs. If that variation advantages that animal as compared to others of that species then the likelihood is that that animal will breed more successfully, potentially passing on that variation to its offspring. Slowly variations accumulate and one species changes into a new species - this is called evolution.
What are the functions of DNA in living organisms?
The functions of DNA in living organisms include storing genetic information, replicating to pass on genetic material to offspring, and providing instructions for the production of proteins essential for cell function and growth.
What is the specialist in genetics called?
A specialist in genetics is referred to as a geneticist. This type of biologist is a physical scientist who studies the science of genes, living organism variation, and heredity.
