c. tt

3. which of the following genotype would be a homozygous genotype
a. ab
b. aa

d. bb

1. Tt

2. Tall

3. BB

Explanation:

1. The genotype of the organism is used to define its genetic constitution. To write down the genotype of an individual an alphabetic symbol is often assigned to it and then depending on whether the person is homozygous or heterozygous, his genotype is written down.

For e.g, If T is the allele for tallness and t for shortness and the person inherits both these alleles then his genotype would be Tt.

2. A person's phenotype refers to the external characters that are visible due to the particular genotype the person has. For eg., if a person inherits an allele for tallness then he has a phenotype of being tall.

3. A person is said to have a homozygous genotype if he carries the same allele for a given trait and is said to be heterozygous if he carries different alleles.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
