Answer:

the correct answer is - a slight difference in factors and their mechanism of transcription such as Nucleotides, polymerase enzyme, and promotor regions.

Explanation:

All types of organism species have exact same nucleotides in their mRNA and DNA. Transcription is also initiated with the similar type of the promotor region in all species.

Slightly differences in any of these or mechanisms can be useful and help to create an evolutionary phylogenic tree or cladogram in various species. The polymerase enzyme is also similar in the various species.

Thus, the correct answer is - a slight difference in factors and their mechanism of transcription such as Nucleotides, polymerase enzyme, and promotor regions.

Masteriza [31]

Answer:

C. More than 5 fingers/toes on each hand/foot

Explanation:

According to the given information, polydactyly is an autosomal dominant trait which means that the phenotype would be expressed in both homozygous dominant and heterozygous dominant genotype.

The given genotype is heterozygous dominant. The individuals with heterozygous dominant genotype would exhibit the polydactyly and would have more than 5 fingers and toes on each hand and foot.

Coevolution : It is the influence of closely associated species on each other in their evolution, they affect each other.

In coevolution , two or more species reciprocally affect  evolution of  each other by natural selection.

 

Coevolution Examples:

There are lots of examples of coevolution, some are here

i) coevolution of Predator-Prey , this relationship is one of the most common examples of coevolution.

ii) coevolution of  Herbivores and plants,

iii)  coevolution of Acacia ants and Acacias and

iii)  coevolution of Flowering Plants and Pollinators and many others.

Nonrandom mating tends to _______ the frequencies of ______ genotypes. increase; homozygous decrease; homozygous increase; heter
Solnce55 [7]
<span>The answer depends of the kind of non-randommating. If the non-random mating is the kind of positive assortative mating then it tends to increase the frequencies of homozygous genotypes. Positive assortative mating when individuals mate with other individuals like themselves. If the non-random mating is the kind of negative assortative mating, then the effect is the opposite as of the positive assortative mating, this is it tends to decrease the homozygous genotypes.</span>
