Answer to Question #204256 in Biology for Jackee

Question

1. Describe the effect of increasing stomatal pores width on the transpiration rate in still air

2.State the dominant allele in the inheritance of tounge rolling and give an explanation 

3. What term is used to describe the genotype of the non tounge-rolling offspring of two parents heterozygous for tounge rolling?

Answer 1

1. Increasing stomatal pores width increases the rate of transpiration as more water molecules evaporate out of the leaf surface.

2. Tongue rolling gene allele is dominant. As a result, if a person inherits one or two copies of the dominant tongue rolling gene allele from parents, then the person would be able to roll the tongue.

3. Homozygous recessive. This person inherited two recessive non-tongue rolling alleles from both parents.
