Two parent plants fertilize to produce all tall offspring, depicted by the genotype Dd. D represents the trait for tall plants and d representing the dwarf trait. The only information you are provided is that the female parent exhibits the dwarf phenotype. Answer the following questions: Male Female What is the genotype of the female parent? What is the genotype of the male parent? Dd all tall What is the phenotype of the male parent (NOT genotype)? (one word only)

Explanation:

Given:

D is dominant on d.

d is recessive allele,

all children are Dd ( tall)

Female parent exhibits the dwarf phenotype, so the genotype of female is  dd.

i) genotype of female parent is  dd ( dwarf).

ii) genotype of male parent is DD(tall).

iii) so, phenotype of male parent is Tall(Dd).

" The alveoli have a very large total surface area and a very good blood supply, provided by the dense network of capillaries that surround them. There is an exchange of gases between the alveoli and their surrounding capillary blood vessels. ... This speeds up diffusion because gases have more area over which to diffuse."
