Answer:
There is a 0% chance that the offspring will be both short and white flowers.
Explanation:
For this we are going to go in and use the Punnett squares. Let´s identify the dominant and recessive genes.
Tall Flowers are Dominant - T(capital for dominance)
Short Flowers are Recessive - t(lowercase for recessiveness)
Blue Flowers are Dominant - W(Capital for dominance)
White Flowers are Recessive - w(Lowercase for recessiveness)
Let´s set up our chart with the information that we have. Its easy to draw the chart, but we need to understand the genes, and make sure that everything is okay!
There is a picture that I took of the chart on the bottom of the page. You can see the dominance of the Tall gene, and the Dominance of the Blue gene. Because none of the offspring have a chance of being short of white, that makes it impossible to have a percentage any higher than 0%.
UNLESS there is a clear mishap or genetically mutated gene in the flower. We never know! I really hope this helped!
Answer:
The frequency of pink flowers will increase to near one over time, while the frequency of white flowers will decrease to near zero.
Explanation:
There are two forces acting as selective pressures.
- Slugs prefer to eat pink-flowering over white-flowering plants → selective pressure against the pink genotype → plants with pink flowers suffer from severe herbivory and are more likely to die.
- Bees prefer to pollinate pink over white flowers → selective pressure favoring the pink genotypes → Plants with pink flowers produce more seeds than plants with white flowers.
When the researcher removes all slugs from the study population, he/she eliminates the selective pressure against the pink genotype, leaving only the force acting in favor of the genotypes. So plants with pink flowers will produce more seeds that will originate more plants with pink flowers. As there is no predator over these plants, they will keep reproducing and growing pink flowers. Over time, the frequency of the pink genotype will increase, while the frequency of the white genotype will decrease.
Answer:
The recessive allele well be masked by the dominant allele in the heterozygous genotype
