You have a dog that drools (d). It turns out that this is a Mendelian trait and recessive in the population of dogs. You breed this drooling dog with another dog that does not drool and is heterozygous for the non-drooling trait. The possible allele combinations for the cross between the drooling dog and non-drooling dog are: Group of answer choices

You have a dog that drools (d). It turns out that this is a Mendelian trait and recessive in the population of dogs. You breed this drooling dog with another dog that does not drool and is heterozygous for the non-drooling trait. The possible allele combinations for the cross between the drooling dog and non-drooling dog are: Group of answer choices.

The possible allele combinations for the cross between the drooling dog and non-drooling dog are:

Explanation:

Available data:

Parentals) dd    x    Dd

Gametes) d   d     D    d

Punnett square)   D     d

                       d   Dd   dd

                       d   Dd   dd

F1) 1/2 = 50% of the progeny is expected to be non-drooling dogs, Dd

     1/2 = 50% of the progeny is expected to be drooling dogs, dd.

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.
