Answer: 3. Structure is a better indicator of a relationship between two organisms because function can be caused by environment, not common ancestry. Structure is better than function because the structure is based on genetics.  For example, the wings on a fly and the wings on a bird perform the same function, but their genetic bases are different.  However, the wings on a bird and the arms on a primate are coded by similar genes even though the functions are different.

The best measure of relatedness is the underlying genomic DNA.

Please help me, I don't understand this
mihalych1998 [28]

Answer:

4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.

Explanation:

Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.

Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.

The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).

RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes

RRtt, Rrtt -> Red petals with short bushes

rrTt, rrTT -> pink petals and tall bushes

rrtt-> pink petals with short bushes.

These are the four phenotype variations possible in this dihybrid cross.

Svetllana [295]

Answer:

See explanation

Explanation:

Taxonomy actually means “arrangement law”. It is the branch of biology that deals with the classification of organisms.

The taxonomic classification system was invented by Carl Linnaeus. It is a hierarchical model of classifying living organisms based on shared characteristics.

Dogs are referred to as 'man's best friend' partly owing to some level of taxonomic relationship between the two species. Dogs and man belong to a class of vertebrates known as mammals- one of the shared characteristics of mammals is that they give birth to their young ones alive.

The taxonomic classification of man is:

Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Primates Family - Hominidae Genus - Homo Species - sapiens.

The taxonomic classification of dog is:

Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Carnivora Family - Canidae Genus - Canis Species - lupus familiaris
