Genetics question?

when red-flowered snapdragons are crossed with white-flowered snapdragons, all of the f1 plants will have pink flowers. If Mendel had used snapdragons instead of pea plants, he would have had difficulty in formulating his principle of





please provide an explanation





a)mutation


b)multiple alleles


c)sex-linked traits


d)dominance

Genetics question?
Babygurl the answer is obviously DOMINANCE.





It is important to know that peas are of complete dominance while snapdragons are incompletely dominant. Had Mendel used snapdragons in his experiment he would not arrive at the 3:1 ratio typical for complete dominance instead he would get a 1 ratio for the F1 because incomplete dominance result in the mixing of colors.





Hope this helps...
Reply:Mendel was lucky in that his pea plants has complete dominant traits in that you have two alleles ( one dominant, one recessive eg A and a) that give 3 genotypes eg AA, Aa and aa and TWO phenotypes eg ummm the dominant and recessive phenotype which could be Tall, Green, Round or whatever.





In snapdragons if you put have RR=red and rr=white you will get Rr=PINK....this is called incomplete dominance where you don't show the dominant triat with Rr but an intermediate pink.....as Mendel was lucky he did not get this in peas, he may not have got his results as quickly as he did before ( prior to this most people thought if you got intermediate characters/traits when mixing alleles.....so the long answer to the Q is d0 dominance.
Reply:d) dominance


d cross with snap dragon is a kind of co dominance
