The answer is a half-filled circle.
In the pedigree charts, squares present males and circles present females. If a female is healthy, the circle is empty (white). If a female is affected with a trait, the circle is filled-in (usually black). However, if a female is a carrier of a disease, which means that one allele is dominant and one is recessive, then the circle is half-filled.

I believe it is a combination of polygenic inheritance and environmental factors. Several genes control the height in humans, giving an overall normal distribution. Environmental factors on the other hand such as nutrition smooth out the curve. It is therefore important to note that Human height is a quantitative, or metric trait, that is, a characteristic that is measured in quantity, and is controlled by multiple genes and environmental factors.
Answer:
Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.
Explanation:
Answer:
Deletion in a nearby gene, chromosome breakage, and translocation of the gene to a heterochromatic location.
Explanation:
Transposable components (TEs), also known as "jumping genes," are DNA sequences that moves starting with one area on the genome then onto the next, in some cases making or reversing mutation and changing the cell's hereditary character and genome size.
At the point when the transposon is extracted from the original site, it may remove a portion of the gene sections alongside it. This prompts the presence of a serious phenotype. Transposable components can likewise cause chromosome breakage. On the off chance that the whole gene is moved alongside the transposon to a heterochromatic location, the gene gets silenced
