yes it can pass
If the parent snapdragons pass along a white gene (W) to the offspring, then the offspring will be white. If the parent snapdragons pass along a red gene (R) to the offspring, then the offspring will be red.

genes 23 from each parent
Chromosomes determine the traits of something, and pass it from parent cell to offspring.
genes
Each parent gives a baby 23 pairs or 46 chromosomes to the offspring
Only half of each parent's alleles are passed to their children. This means that parent 1 who is Aa at one gene locus will only pass A or a on to each offspring. Parent 2 may be AA, aa or Aa and will also only pass one allele on to each offspring.
When a parent is going to have an offspring the offspring only gets half a chromosome from each parent, they combine to make one chromosome then that chromosome gets copied until there are 23 pairs of chromosome's. This is how you get your features.
It is possible for a parent with phenylketonuria to pass the condition to their offspring if both parents are carriers of the PKU gene mutation. In this case, there is a 25% chance that their child will inherit two copies of the mutated gene and develop phenylketonuria. Genetic testing can provide more information on the risk of passing PKU to offspring.
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.
