Answer:
Tongue-rolling is dominant, and both parents were heterozygous
Explanation:
Tongue rolling is a type of variation in human beings. When allelic genes are not identical as in Tt, the condition is referred to as heterozygous. An individual with such a genotypic condition is referred to as a heterozygote.
Both parents had a genotype of Tt and they could roll their tongues because T is dominant over the t gene.
T t
T TT Tt
t Tt tt
TT : Tt : tt
1 : 2 : 1
In a heterozygous parent Tt, the chance of producing T gamete from both parents is each 1/2 each. Similarly the chance of forming t gamete is 1/2. Therefore, the chance of gamete T and t fusing to get genotype Tt is 1/2*1/2=1/4.
The ratios of phenotypes are 3/4 will be able to roll the tongue and 1/4 will not be able to roll the tongue.
The mode of inheritance was monohybrid inheritance since one characteristic like tongue-rolling is controlled by a single pair of hereditary factors contributed by both parents.
The process of classifying an organism into a clade by comparing similarities in body symmetry and other morphological traits comprises - 1. body plan-based cladistics cladistics based on body plan, morphology-based phylogeny.
<h3>What is cladistics based on body plan ?</h3>
A method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.
- Cladistics is a method of biological classification in which groups of species (or "clades") are assigned based on theories of most recent shared ancestry.
- The evolutionary link between recent ancestors and descendants, or the course of evolution, is shown via cladistics. An aid to representing it is a cladogram. Since clades serve as the foundation for phylogenetic trees, cladistics is a component of the phylogeny.
<h3>What is molecular-based phylogeny ?</h3>
Molecule structure is used in molecular phylogeny to shed light on an organism's evolutionary connections.
- A so-called phylogenetic tree represents the findings of a molecular phylogenetic research. DNA, RNA, and proteins are components of all living things.
- Molecular phylogenetics creates a phylogenetic tree by drawing conclusions about the evolutionary links that derive from molecular evolution.
<h3>What is Morphology-based phylogeny ?</h3>
Using anatomical features, morphological phylogenetics infers evolutionary trees. Node: A branching point when an ancestral lineage splits into two (or more) daughter lineages in an evolutionary tree.
The ability to discuss the phylogeny of fossil taxa and how they relate to modern taxa is the unquestionable benefit of morphological data. However, their strategy prevents us from addressing the situation of extinct taxa for which there is no way to gather DNA data (i.e., almost all of them).

We know that copper sulfate can be used in an experiment to test whether or not a protein is at hand, etc. Hope this helps!
Answer:
Denaturation process: The DNA template
Annealing process: Primers
Elongation process: dNTPs and Taq polymerase
Explanation:
For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.
I hope this clarify you inquiry.
