Conjugation
The process by which isogamous organisms exchange genetic information during fertilization is called conjugation.
In process of meiosis. The hypothalamus or the master gland in most animals, including humans send signals to the ovaries and testes of the reproductive system. In response to these signals, these ovaries and testes undergoes thesex cells division which is called meiosis<span>. </span>Spermatogenesis <span>in male gametes, is the process of sex cell division among sperm cells. On the other hand, </span>oogenesis<span> is for the female gametes. These cell divisions among respective gametes produces haploid cell which only contain one pair of chromosomes, in number -23.<span> </span></span>
Answer:
The Sun
Explanation:
Nearly everything eats sunshine – or eats something else that ate sunshine. The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter.
To compare the perioperative results of frozen elephant trunk (FET) vs. traditional elephant trunk (ET) procedures for aortic arch repair. 390 individuals had aortic repair with elephant trunk reconstruction between 2002 and 2018 at 9 facilities: Aortic dissection affected 37% of patients who received a FET (mean age: 65+/-13 years, 30% female), while 43% of patients who received an ET (mean age: 63+/-13 years, 37% female) experienced aortic dissection. In-hospital mortality, stroke, and spinal cord injury were among the outcomes of interest (SCI).
<h3>What is Aortic arch ?</h3>
The top portion of the principal artery sending blood away from the heart is known as the aortic arch. A combination of symptoms and signs known as aortic arch syndrome are linked to anatomical issues in the arteries that branch off the aortic arch. The valves, chambers, and accompanying vessels that make up the heart's interior.
<h3>What is conventional techniques ?</h3>
Conventional methods assess the long-term heat stability of polymer products at temperatures below their melting points, for instance, through accelerated aging in "circulating air ovens" until degradation effects like discolouration and embrittlement become apparent.

Answer:
12:3:1
Explanation:
<em>The typical F2 ratio in cases of dominant epistasis is 12:3:1.</em>
<u>The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus</u>. There are different types of epistasis depending on the type of alleles that are interacting. These include:
- Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.
- Other types of epistasis include <em>recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).</em>
