Crossing over between two chromosomes

Answer:

Crossing-over

Explanation:

During Prophase I, which is the first division stage of meiosis I, homologous chromosomes pair up with each chromosome aligning with its homologue partner to form a TETRAD structure. At this stage, segments of each homologous chromosome break and get refixed interchangeably i.e trade parts. This process is called Crossing-over or RECOMBINATION

Crossing-over is the process whereby two chromosomes of a homologous pair (non-sister chromatids) exchange equal segments with each other to form two recombinant chromosomes.

Crossing-over accounts for genetic variation due to the swapping of genetic material. Some of the daughter cells receive daughter chromosomes with recombined alleles. Due to this genetic recombination, the offspring have a different set of alleles and genes than their parents do.

Answer:

<em>The offspring which carries the allele II will be homozygous dominant.</em>

Explanation:

A dominant trait can be described as a trait which masks the effect of a recessive trait. A recessive trait can be described as a trait which gets masked by the dominant trait.

A homozygous dominant trait occurs when both the alleles for the gen are dominant. A heterozygous dominant trait occurs when one allele is dominant and the other is recessive for the trait.  

Hence, a homozygous dominant trait will carry the alleles II.

What are the advantages and disadvantages to sunscreens containing common active ingredients such as oxybenzone, octocrylene, an
aleksklad [387]

Sunscreens contain chemical ingredients in their compositions, such as avobenzone, oxybenzone, octocrylene, homosalate, octisalate and octinoxate, which have been linked to health problems such as hormonal disruptions, cancer, as well as liver and kidney changes.

<h3>What is oxybenzone, octocrylene, and homosalate bad for?</h3>

Oxybenzone, octocrylene, and homosalateto protect from UVA also penetrates deep into the skin. The penetration  into the human body can cause several problems in human health such as

  • allergic reactions
  • cell mutation
  • deregulation of hormonal processes,
  • etc.

With this information, we can conclude that Oxybenzone, octocrylene, and homosalateto is considered a hazardous eye irritant and, as an allergen, is also known to cause skin allergies.
