Science 1 question. Punnett Squares.?

1.What do the letters in each box of a Punnett square tell you?


A. the possible combinations of alleles in offspring based on the parents' genetic makeup


B. that both parents show characteristics of the dominant trait


C. how to assemble a genetic map of the chromosome on which the alleles are located


D. the full pedigree of the geraniums





Thanks!!

Science 1 question. Punnett Squares.?
The answer is A.





B is incorrect, because punnet squares are used when the parents are homozygous for dominant or recessive traits, and when the parents are heterozygous.





C is incorrect because you can only assemble a genetic map of a chromosome when you are using linked genes - genes that are on the same chromosome.





D is incorrect because punnet squares are not pedigrees. Pedigrees give you the ancestral medical history of an organism (or human family) as far back as records show. Punnet squares only give you information on the probability, given the parent's genotypes, of the offspring having a particular genotype.
Reply:I believe it is A
Reply:Answer is A
Reply:option a is correct,as we are talking of only letters,its permutations and combination that which allele set goes in offspring and its probability
Reply:Definitely A.
Reply:I think it's "A", but I hated that segment of Biology.
