Explanation:
Broken up land land contributes to a loss of species diversity through geographoc isolation. Geographic isolation is the physical barrier dividing the communities. It usually stops the gene flow between species in a process called allopatric speciation, contributing to reproductive isolation.
Further Explanation:
Spontaneous modifications in the genome can occur during the cycle of cell division, called mutations. These errors occur as copies of the DNA are produced within the cell; mutations may range from small modifications called single nucleotide polymorphisms to large-scale deletions and multi-gene additions.
Such mutations create variations that within a group become dominant, resulting in the creation of different, genetically distinct organisms called species.

A normal cell contains 46 chromosomes.
Gametes only contain 23 because they will be paired with an opposite gamete cell upon fertilisation
- Egg contains 23
- Sperm contains 23
Together they make the normal amount of 46
Answer:
GENE
Explanation:
The functional segment of the DNA that contain instructions for a specific trait is known as a gene.
C. cells . are the basic units of life
Let's suppose that "long" is the dominant allele and "oval" is the recessive allele.
let's suppose also that red + white genotype give a pink phenotype
every radish has 2 genotypes for each gene, one from the mother and one from the father
The proportions are: if the radish are homozygotes
red red; long long x white <span>white ;</span> oval oval
red white oval long ; red white oval long ; red white oval long ; red white oval long
We will have 100% of pink - long radish.
A crossmatch from homozygotes species give always a unique phenotype
