Answer:
Population bottleneck
Explanation:
Population bottleneck can be defined as a sharp decrease in a population size which can be attributed to various environmental influences including fires, hurricane, famines etc.
This leads to loss of alleles and a small population. With a smaller population size, celebrities mutations can occur, producing several inherited disorders.

Please mark as brainliest....thanks!!!
Explanation:
An organism can be homozygous dominant if it carries two copies of the same dominant allele, or homozygous recessive if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene.
A homozygous recessive allele combination contains two recessive alleles and expresses the recessive phenotype. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r)

Yes it's a protein called Hemoglobin in the red blood cells and it carries oxygen around your body and to your lungs, so it is TRUE.

Four cells and 10 chromosomes each. Before going through meiosis ii it has to go through meiosis i (homologous chromosomes separate) first to form two cells. Then both cells goes through meiosis ii (sister chromatids separate) to form two cells each. Therefore 4 cells.<span />
Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.
Explanation:
Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.
