A certain eukaryotic organism has multiple, distinct genes with highly similar sequences that are expressed at different times i
vlabodo [156]

These genes could have arisen by gene duplication.

<h3>What is gene duplication?</h3>

Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.

Gene duplication is a phenomenon that can happen through a variety of ways:

  • Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.
  • Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.
  • Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

Help please? what traits do all organisms with no internal thermoregulation have?
sukhopar [10]

Answer:

The answer to the question is C ectothermy

Explanation:

The answer to the question is C ectothermy

The traits which all organisms with no internal thermoregulation have are called an Ectothermy. Ectothermy is an organism in which the inner behavioral heat sources are significant in the regulation of body temperature. This organism depends on their ecological heats source, which allows them to work at an efficient rate. Some of this organism stays in an area where temperatures are nearly constant.
