What element do organic compounds always contain?
Organic compounds always contain the element carbon.
Which element is always present in sulphides?
Sulfur is always present in sulfides.
Why should i handle acids carefully?
Depending on the acid and the concentration, there is a danger, when using strong acids, of blindness if splashed in the eyes. Or severe burning if the acid touches the skin. Always wear acid resistant clothing, apron, gloves, etc. and also wear safety goggles. Avoid breathing in any fumes.
Can acid blind you?
Depends how strong the acid is. Orange juice and Lemon juice are acids but they don't typically blind us it just stings a lot. Look at the acid and bases scale to see how strong the acid is then you'll know if it can blind you.
Why is a son who receives the allele for combinations from his mother always colorblind?
Since the mother would be considered a carrier, the gene will be produced in the offspring. the son will receive that gene and will be colorblind.
A womens father is colorblind She marries a colorblind man Will there son or daughter be colorblind?
Colorblindness is an X-linked recessive disorder. This means girls (who have the sex chromosomes XX) must have a colorblind X from dad and a colorblind X from mom. Boys only need to have one colorblind X to be colorblind because they have sex chromosomes XY (and have only 1 X). If the dad has it, he has the colorblind X. If the daughter has it, she must have gotten her mom's colorblind X. If the mom is colorblind, then every child they have will be colorblind. If the mom is not colorblind, then she must be a carrier - she must have 1 normal X and 1 colorblind X. Mom is either colorblind (with 2 colorblind Xs) or she is a carrier. Dad is definitely colorblind.
Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
What is an allele that always shows up in an organism's phenotype called - an allele that masks the other allele?
An allele that always shows up in an organism's phenotype and masks the expression of another allele is called dominant. Dominant alleles are always expressed, even when paired with a recessive allele.
What is the allele that will always show physically?
The dominant allele will always show physically in an individual, while the recessive allele will only be expressed if paired with another recessive allele.
Colorblind male not colorblind female can there kid be color blind?
He will always be colorblind in that case because the defective gene is carried on the "X" chromosome, which males only have one of. You see, the colorblindness gene is recessive, which means if it is paired with a regular color seeing gene it is hidden, and the person can still see the difference between red and green. Because males have only one "X" chromosome, if they get the colorblindness gene from their mother, it will always lead to colorblindness. Side note: Males cannot receive the colorblindness gene from their Father, as he cannot give a "X" chromosome to his son. If he did, his son would be a daughter.
If and individual has one dominant allele and one recessive allele will the recessive allele show up?
No, the dominant allele will be expressed in the individual's phenotype, masking the presence of the recessive allele. The recessive allele will only be expressed if an individual inherits two copies of the recessive allele.
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
What is the ratio of colorblindness men and women in Pakistan?
The ratio of colorblindness of men to women anywhere is virtually 1:0. Colorblindness is a sex-linked disease and you have to know a little biology to know why men account for almost 100% of the world's colorblind population. See, at birth, the genes of the mother and father fuse together to produce the offspring. The male sex gene is XY while the female is XX. So if the offspring is male, the offspring receives a Y from its father and an X from its mother (since the mother can only give Xs). And if the offspring is female, the offspring will receive an X from both parents. So the chance of having either a boy or a girl is always 50/50 and it comes down to what the father gives. Colorblindness is a sex-linked disease, as mentioned earlier, which means its coded on the sex genes. Sex-linked diseases are almost always located on the X chromosome. And to get this gene, you must have 100% of your Xs coded for it. A female could become colorblind only if she receives an X from both parents that code for the disease. A male could become colorblind if he receives an X from his mother that codes for the disease. So it is a much greater chance for males to become colorblind than females, because every rarely does it happen that a female receives a sex-linked disease. However, a woman can still receive a gene that codes for the disease. If she receives just one, she is a carrier of the disease and may pass it on to her offspring. If she receives two, she has the disease. If she receives none, she's free of the disease.
What does a dominant allele always do?
A dominant allele expresses its trait in an individual when present, masking the effect of a recessive allele. This means that if an individual has at least one copy of a dominant allele, the associated trait will be displayed.
What is an Dominant allele?
A dominant allele is a gene that holds a certain characteristic that is superior to a recessive allele. The dominant allele ALWAYS has its trait shown in the body of the recipient, except when both alleles in a gene are recessive.
Will a dominant allele always increase in frequency over time?
No, a dominant allele will not always increase in frequency over time. The frequency of an allele in a population can be influenced by various factors such as natural selection, genetic drift, and gene flow.
