Answer:

a) 1 tall:1 dwarf

Explanation:

Let's assume that the allele T is responsible for tallness while the allele "t" imparts dwarfism. The genotype of a homozygous recessive dwarf pea plant is "tt" and that of the heterozygous tall pea plant is "Tt". The heterozygous tall parent would make two types of gametes in equal proportion while the homozygous parent would produce all the gametes carrying "t" allele only.

A cross between Tt and tt gives progeny in following phenotype ratio= 1 tall: 1 dwarf.

zheka24 [161]

An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.

<h3>Variation of ecological habitats within a species is characteristic of which type of diversity?</h3>

The variation of ecological habitats within a specie is character of the type of diversity is known as Ecosystem Diversity.

Ecosystem is defined as the different kinds of habitats, ecological processes and communities. A biological community is defined by the specie which occupy a specific area and the interactions between the species.

So we can conclude that: An ecosystem is a geographic area where plants, animals, and the other organisms work for the existence of bubble life.
