HOXC8 gene encodes a protein that has a role in the development of the cartilage. This gene is a member of the HOX group gene that enables the differentiation of the body segments. These genes encode for transcription factors that activate the expression of other specific genes guiding the differentiation of body segments into specific structures.
Answer:
Crossing over
Explanation:
Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.
Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.
Answer: In vitro fertilization
Explanation:
In vitro fertilization (IVF) involves some procedures used to help with fertility. This series of procedures are usually complex and can help prevent genetic problems and assist with the conception of a child.
During IVF, mature eggs are collected from the female ovaries and sperms from the male and fertilized in the laboratory. The fertilized egg are then transfered back into the uterus for its growth and development.
The sperm and eggs could be from partners who have decided to carry out IVF or from donors. IVF is usually Carried out by high rating laboratory. One full cycle of IVF takes about three weeks. IVF are usually expensive and could take a longer time if splits into different aspects.
IVF is an effective reproductive technology.
By eating plants and other animals, because they obtain their carbon from food.
