Which of the following is a false statement?

A.Phenotype determines genotype


B.Combinations of alleles are known as a genotype


C.A gamete will only receive one allele or another from a pair


D.The inheritance of one trait does not affect the inheritance of another trait

Which of the following is a false statement?
A is the false statement since there is not always a direct correlation between phenotype and the genotype. In addition, A would be backwards anyway. Genotype would determine phenotype up to a point, but genes are not always expressed, so a given genotype does not always cause a given phenotype. Those who are answering B seem to be mistaking genotype with phenotype. Genotype refers to the combination of allelles, phenotype refers to expressed traits, ie., appearance. So if B had used phenotype, it would be wrong.





According to Wikipedia:





An individual's genotype for that gene is the set of alleles it happens to possess.


http://en.wikipedia.org/wiki/Allelle





Phenotype is determined to a large extent by genotype, or by the identity of the alleles that an individual carries at one or more positions on the chromosomes.


http://en.wikipedia.org/wiki/Phenotype





Typically, one refers to an individual's genotype with regard to a particular gene of interest and, in polyploid individuals, it refers to what combination of alleles the individual carries (see homozygous, heterozygous). Any given gene will usually cause an observable change in an organism, known as the phenotype. The terms genotype and phenotype are distinct for at least two reasons:





To distinguish the source of an observer's knowledge (one can know about genotype by observing DNA; one can know about phenotype by observing outward appearance of an organism).


Genotype and phenotype are not always directly correlated. Some genes only express a given phenotype in certain environmental conditions. Conversely, some phenotypes could be the result of multiple genotypes. The genotype is commonly mixed up with the Phenotype which refers to the physical appearance

Reply:B,C, %26amp; D are definetly true.A is wrong because genotype(allels on a gene) determines phenotype (the appearance).
Reply:Are you having us do all of your homework? I've noticed a lot of questions from ya. It'd help you more long term if you figure it out yourself, or at least ask for HOW the other people figured out the right answer...
Reply:The only one that is ALWAYS true is B.





A - False: Genotype and environment determines your phenotype. The only thing that phenotype affects is if people think you're hot.





B - True





C - In some rare cases, the individual will recieve both pairs from one parent and none from the other. In general, a gamete will only receive one allele from each individual parent. Also, in parthenogenic creatures each offspring is a clone of the mother (so it gets both pairs)





D - Again, in most cases this is true, but... there are circumstances where the presence of one allele will destroy or alter the expression of another inherited allele (sperm killers, for example).
Reply:A is false. Genotype is the expression of alleles in your DNA. Phenotype is your actual physical characteristics, such as eye and hair color. Therefore your phenotype is based on what your genotype is.
Reply:a pheno type determines genotype


its the other way around you have to have the genes for them to show up


therefore genotype determines phenotype
Reply:B is false, combinations of alleles is not called genotype.
Reply:Te answer is A


One phenotype (what you can observe ie. red hair) can be determined by diffrent genotypes.
Reply:B. because the genotype is the genetic make-up of the alleles and it is not always the combination.
Reply:A, phenotype is appearance, genotype is composition
Reply:A is false.


It's the other way around; genotype determines phenotype.
