A mistake in DNA replication before meiosis produces an organism that is better able to outrun predators.
Explanation:
The genetic variation results from the different alleles of a population. The mutation or mistake in DNA replication would cause gene variants which may be beneficial. The variation in the DNA sequence of genome results in variants in small population.
Genetic variation is the cause of natural selection and eventually, evolution takes place with beneficial traits.
It is mentioned in the question that resulting offspring having received the mutant allele could result in better surviving capabilities or phenotypic traits as they are able to outrun predators.
<u>The right answers are:</u>
HOX genes are very similar in all animals.
Many species share much the same DNA.
Plant and animal cells have almost all of the same structures.
Answer: There are certain physical and internal aspects of living organism that is used for the classification of animals.
Explanation: The characteristics that define an organism to be classified as animal are:-
- Segmentation that defines the segments on the bodies of the animals which are of different kind
- Whether the animal is in the category of chordata or non-chordata
- Presence of embryo stage and number of tissue layers that are getting formed while the organism is developing
- There are most chances of sexual reproduction.
