DD is homozygous dominant, the dominant allele will shown so they will have dimples.
<h3>Homozygous dominant:</h3>
- When an organism is homozygous, it contains two copies of the same allele for a gene.
- When two copies of the same dominant allele or two copies of the same recessive allele are present in an organism, it is said to be homozygous dominant or homozygous recessive.
- Homozygosity is the presence of two dominant alleles (AA) or two recessive alleles (aa).
- The recessive allele is suppressed by the dominant one.
Heterozygous dominant:
- The two distinct alleles in a heterozygous genotype interact with one another. This controls how their characteristics are shown.
- This encounter frequently centers on dominance.
- The stronger allele is referred to as "dominant," whilst the weaker allele is referred to as "recessive." The dominant allele covers up this recessive one.

Answer:
B. natality + immigration = mortality + emigration
Explanation:
Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.
Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.
Some of the factors that influence migration selectivity are income level, age, education, gender etc.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Therefore, the equation which would create a stable population is given by the formula;
Natality + immigration = mortality + emigration.
