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?
Phenotype determines genotype. It's the other way around. Your genotype is a collection of alleles. Your phenotype are the genes that you express (Eg. hair colour)
Reply:"A" is false.


It's the other way round, I think. It's been a long time since bio 101.
Reply:A is false. Genotype determines phenotype.
Reply:b
Reply:a) is stated backwards, therefore is false.
Reply:A is false.





This is a bad question. D is also sometimes false. Sometimes, the gene loci for two different traits are so close together on the same chromosome that the there's no crossover point between them, so they'd always be inherited together. (Ask your teacher about this). Mendel was very lucky in choosing the traits he studied in peas for "independent assortment."
Reply:The false statment is A.





It would be true as, "genotype determines phenotype."


Genotype is the actual gene sequences.


Phenotype is the actual expression of the gene sequence.
