When a population has a gene with four alleles circulating, how many possible genotypes are there?

10 possible genotypes

Explanation:

Genotype is defined as the genetic makeup of an individual, ie the set of all genes in that organism. The gene, in turn, can be defined as a specific nucleotide sequence of DNA that stores hereditary information. They present information that will be responsible for a given characteristic. Each individual has a specific genotype that is made up of genes from their parents that will be kept for the life of the organism.

To know how many genotypes a population can present from the number of alleles, we must calculate by the formula: alleles x (alleles+1)/2

This way we will have:

4x (4 + 1) / 2 =

4x (5) / 2 =

20/2 = 10 possible genotypes.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
