A young man wants to determine if he is a descendant of Henry of Navarre and Eleanor of Aquitaine—two of his favorite historical

characters. He sends a cheek swab to a DTC company and is offered a choice: the company can assess either the sequence of the man's Y chromosome or his mitochondrial DNA. Which should he choose?

Answer:

He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.

Explanation:

  • Mitochondrial DNA haplotypes are  specific regions of mitochondrial DNA that cluster with other mitochondrial sequences to show the phylogenetic origins of maternal lineages.
  • Mitochondrial DNA haplotypes are associated with a range of phenotypes and disease.
  • Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function.
  • Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.

What shuffles genes and increases genetic variation in gametes during meiosis, when these homologous pairs are paired up ?
Marizza181 [45]

Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.

<h3>What is crossing over?</h3>

Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.

It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.

It actually occurs at the pachytene stage of prophase I of meiosis cell division.

Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.

Biological transmission differs from mechanical transmission in that biological transmission involves reproduction of a pathogen
Taya2010 [7]

Biological transmission involves reproduction of pathogens in an arthropod vector prior to transmission. In terms of epidemiology, we can term a vector as an organism that is from infected to the uninfected. An infected organism which develops biological vector passes it to its host. For example a mosquito.

 A mosquito being a mechanical vector carries an infected organism to its host either through the legs or through the other body parts
