Systematics is the study of diversity of organisms including past and present and relationships among living things. Systematics as analytical approach, help us to understand the diversity and relatedness of both existing and extinct organisms. Systematics is also important in carrying out the conservation issues because, it attempts to explain the biodiversity which is related to different kinds of species and could be used in preservation and protect the endangered animals and plants.

The ability to curl one's tongue into a U-shape is a genetic trait. Curlers always have at least one curler parent but noncurler

irina1246 [14]

Answer:

A noncurler has a genotype cc.

Explanation:

If curlers always have at least one curler parent, it is possible being "curler" will be related to a dominant allele, in this example, "C". So, being "noncurler" could be a recessive trait. Noncurler can have one or both parents who are curlers, and this is concordant with a recessive inheritance if both parents are heterozygous (Cc) (with a probability of 25% of being "noncurler"). Also, it is possible if one parent is heterozygous and the other is homozygous for c (Cc x cc), this with a probability of 50% ob being "noncurler".

The Punnett square shows this clearly.
