The genetic code is copied during the process of?
Its trancription.
Does cossing over lead to genetic variation?
Crossing over: exchange of parts of DNA in a homologous chromosome in the area where they come in contact with each other. Then this chromosome splits, during meiosis, to form a daughter cell (gamete) with a haploid number of chromosomes. During fertilization, the two gametes fuse into one cell containing now a diploid number of chromosomes. This process leads to genetic diversity and variation.
During meiosis crossing-over gene exchange between chromosomes may occur Crossing-over usually results in?
The result of crossing over is genetic diversity. More specifically, it is a hybrid chromosome with a unique pattern of genetic material. Does this answer help?
What is the genetic code read in?
Three-base triplets called codons. Each codon will be translated into an amino acid during the process of translation.
During transcription the genetic information is rewritten as a molecule of?
During transcription, the genetic information is rewritten as a molecule of
Why do members of chromosome pairs separate during mitosis?
This process results in "Genetic Diversity". [Short Answer]
What factors contribute to genetic diversity?
The way the chromosomes line up during meiosis.
Which phase of meiosis do diversification occur?
Diversification occurs during the crossing over phase of meiosis, which is Prophase I. During this phase, chromosomes exchange genetic material, resulting in the recombination of genetic material between homologous chromosomes. This process increases genetic diversity and contributes to the unique combination of traits in offspring.
What changes during a mutation?
Mutations can improve the trait, harm the trait, or neither.
Chromosomes exchange genetic information through the process of what?
Chromosomes exchange genetic information during a process called crossing over. This occurs during meiosis
When sex cells randomly combine during fertilization to produce offspring there is?
increase genetic diversity
What are two ways that sexual reproduction helps create and and maintain genetic diversity?
Sexual reproduction helps create and maintain genetic diversity by: # The independent assortment of chromosomes during meiosis. # The random fertilization of gametes.
What is the ultimate souce of genetic variation and the basis for the diversity of life on earth?
Interchange of genetic material during meiosis and random union of male nad female gametes during fertilization.
The genetic code is copied during the process of?
Its trancription.
What is the result of crossing over?
The crossing over alleles is critical to the survival and genetic diversity of a species. The results of the random crossing over of alleles is that the offspring will have chance inheritance of certain characteristics from their parents (as opposed to being genetic clones with no diversity). The diversity of phenotypes are among the major manifestations of random crossing.
Why do we have a mix of our mother's and father's characteristics?
We inherit a mix of our mother's and father's characteristics through a process called genetic recombination. This occurs during the formation of reproductive cells (eggs and sperm) when segments of genetic material from each parent combine to create a unique genetic blueprint for the offspring. This mixing of genetic information contributes to the variability and diversity seen in offspring.
What are the changes in the genetic code called that occur during DNA?
Mutation
