Answer: Option D.

Explanation:

An ionic bond is defined as a chemical bond forms when two oppositely charged ions undergo electrostatic attraction. Ionic bonds always formed between a metal (cation), and a nonmetal (an anion).

Ionic bonds are formed when a cation (metal) donates an electron to anion (nonmetal). for example formation of Sodium Fluoride (NaF), sodium (cation) with atomic number eleven is having one valence electron in its outer orbit and fluoride (anion) with atomic number nine require one atom to complete its orbit, so the sodium atoms transfer one electrons to fluoride and leads to the formation of an ionic compound.

Hence, the correct option is D.

True

A genotype is the combination of genes in its DNA of the organism that determines its traits

Explanation:

Gametes from parents contribute different alleles of genes to their offspring. This why gametes carry only one copy of genetic material of the organism. They later fuse to form a zygote with a full genetic copy and capable of developing into an full organism.

Depending on which kind of alleles the parents pass down to the offspring will determine the offspring's genotype. The genotype of the offspring will, on the other hand, affect its phenotype which is the outward characteristic. An example is the sickle cell trait. If both gametes from the parents contribute the recessive alleles of the gene, then the offspring will be homozygous recessive for sickle cell genotype and this will show in the phenotype pf the person who will have sickle cell shaped blood cells.
