D reproductive cells!

Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

What is the purpose of fit check technique for masks? essay question
anygoal [31]

Tight-fitting respirators must seal to the wearer’s face in order to provide expected protection. This includes disposable respirators (also called “filtering facepieces”). Therefore, fit testing is required in the US by the Occupational Safety and Health Administration (OSHA) before a user wears a mandatory respirator on the job, and must be assessed at least annually. In addition, fit tests should be performed:

Whenever a different size, style, model or make of respirator is used.

When any facial changes occur that could affect fit, such as significant weight fluctuation or dental work.

A good fit means the respirator will seal to your skin. A respirator can only work when air passes through the filter. Air will take the path of least resistance, so if the seal isn’t there, the air will go around rather than through the respirator – and therefore lessen the protection.

Safety glasses, hearing protection, face shields, hard hats and coveralls can all vie with a respirator for real estate on a person’s face, head or body. For instance, if a half face respirator doesn’t fit well (especially if it’s too large), it can overlap with glasses. The more that happens, the more fogging can potentially occur on glasses, and the more likely it is that they’ll interfere with the respirator’s seal.

Alex Ar [27]

Answer:

<h2>Alice's daughter Alix =X X*   </h2><h2>George V= XY </h2><h2>Progeny  are;</h2><h2>XX, XY, X*X, X*Y </h2><h2>50 % males would be  infected </h2><h2>50% male normal</h2><h2>50% female normal, </h2><h2>50 female carrier. </h2>

Explanation:

Hemophilia is an inherited disease and it follows  an X-linked recessive pattern. The genes for hemophilia disease are located on the X chromosome. In males one mutated copy of the chromosome X  is sufficient to cause the condition, because male contain only one gene. Female  contain XX chromosome, so both the chromosome must have mutated for causing this disease.

According to  study of  Queen Victoria (1891-1901) of England, Alice's daughter Alix was X linked carrier and George V was normal male,

so if they got married, their children would be  

parents genotype  X X*   XY

progeny  

XX, XY, X*X, X*Y

50% males would be  infected

50% male normal

50% female normal,

50 female carrier.
