In Black Angus cattle, the color black is what type of genetic trait? recessive
incomplete
dominan
genotype

dominant

Explanation:

The "gene" of an organism consists of two alleles. One allele comes from each parent. A genetic trait is said to be "dominant" even if there's only one copy of dominant allele present; however, a genetic trait is said to be "recessive" if there are two recessive alleles present.

In Black Angus cattle, the dominant color is "black." They are even named after their color. The recessive trait is "red." In order for a Black Angus cattle to be red, it needs to have two alleles for the recessive trait (red). However, it is easy for the cattle to be black as long as it has one allele for the dominant trait.

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.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.
