Explanation:
a social group can be defined as two or more people who interact with one another, share similar characteristics, and collectively have a sense of unity. Other theorists disagree however, and are wary of definitions which stress the importance of interdependence or objective similarity. Instead, researchers within the social identity tradition generally define it as "a group is defined in terms of those who identify themselves as members of the group."[3] Regardless, social groups come in a myriad of sizes and varieties. For example, a society can be viewed as a large social group.

Answer/Explanation:
<h3>Incomplete dominance</h3>
In incomplete dominance, one allele is not entirely dominant over the other, so heterozygotes (organisms with two different alleles for the gene) show an intermediate or blended phenotype.
For example, consider flower colour.
- If the allele for red flowers (R) was dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, and rr) and two possible phenotypes. (Red (RR and Rr) and white (rr)).
- However, if the allele for red flowers (R) was incompletely dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, rr), and three possible phenotypes (red (RR), white (rr), and pink (Rr))
<h3>Co-dominance</h3>
In incomplete dominance, two alleles are both expressed, one is not dominant over the other. Therefore, heterozygotes (organisms with two different alleles for the gene) express both traits.
For example, consider flower patterns.
- If the allele for spots (F) was dominant over the allele for stripes (f), then there are three possible genotypes (FF, Ff, and ff) and two possible phenotypes. (Spots (Ff and ff) and stripes (ff)).
- However, if the allele for spots (F) was co-dominant to the allele for stripes (f), then there are three possible genotypes (FF, Ff, ff), and three possible phenotypes (spots (FF), stripes (ff), and spots and stripes (Ff))
