The type of chromosomal mutation that occurs here is an example of a deletion mutation. Specific genetic data, or DNA is removed and the remaining portions of chromosomal information have rejoined.
I would say photosynthetic bacteria are the most important, because if they disappeared most of the oxygen in the atmosphere wouldnt be here and complex life like humans wouldnt exist
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.

How can reproductive isolation lead to speciation<span>? If populations cannot mate successfully with one another, genetic differences may accumulate in the populations. Over time they become very different and give rise to new species.</span>
