The statement 'a suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene' is TRUE about mtDNA.
<h3>What is mitochondrial DNA?</h3>
Mitochondrial DNA (mtDNA) is a special class of genetic material contained inside the mitochondria of eukaryotic organisms.
This genetic material (mtDNA) may result very useful to identify samples by making comparisons of the nucleotide sequence.
Mitochondrial DNA typing is a useful strategy used in criminology based on matching an unidentified sample of mtDNA with another obtained at the crime scene.
In conclusion, the statement 'a suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene' is TRUE about mtDNA.

Hi
There are different ways in which Australian fire is affecting the region:
1: Direct effects:
Almost 18 million hectares of land has been completely destroyed due to fire in Australia from 2019-2020, it has destroyed over 5900 buildings and 2900 homes. Moreover, along with some human fatalities millions of animals have been killed due to fire.
2: Economic effects:
It is very clear that the fire has badly affected the economy of the country although accurate figures are being analyzed at the moment. Due to extended damage of infrastructure, farming and tourism structure is severely affected and number of tourists visiting the land is getting less. Many institutions and businesses are closed due to excessive pollution in air.
3: Environmental effects:
Initially fire caused the devastation if around 1 billion animals , however the number will continue to increase due to adverse effects of fire such as loss of food and habitat in coming weeks. The fire has caused the devastation of not only animals but many plants and trees which were a source of oxygen so there are major chances for abrupt increase in the temperature of Australia in the coming years which will lead to global warming.
Moreover, <em>the biodiversity decline can also cause loss of some rare specie or even their extinction which ultimately may reduce the biodiversity of all over the world.</em>
There are many other effects of Bushfires of Australia such as psychological and physical health of people living there who are living in an environment that is getting bad to breathe, however studies are being done to better analyse the situation and predict consequence in a more logical way.
Hope it helps!
<h3><u>Answer;</u></h3>
white eyes are homozygous recessive
<h3><u>Explanation</u>;</h3>
- <em><u>Thomas Hunt Morgan work with the fruit fly showed that genes are linked in a series on chromosomes and are responsible for identifiable, hereditary traits. </u></em>He was the first to identify that genes are linked to the same chromosome.
- <em><u>According to his hypothesis he stated that genes that are linked are arranged linearly on a chromosome, while those genes with low combination frequencies must be closer together and thus difficult to separate</u></em>.
- When a gene contains two similar alleles that is, either two dominant alleles or two recessive alleles then it is called homozygous dominant and homozygous recessive respectively. White eyes of a fruit fly is an example of homozygous recessive
