Answer:
Genetic mapping for unequivocal identification of the potentially causative mutation
Explanation:
Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.
They are produced by meiosis
Humans may be able to cure certain diseases. Also they will develop a greater knowledge of humans.
Answer:
Sea anemones are marine predatory animals. They are like a terrestrial flowering plant due to their colorful appearance. They are coming under the phylum cnidaria.
Sea anemones are found in different forms called a polyp. It has a columnar trunk, on the top of the trunk an oral disc and centrally placed mouth. The mouth is surrounded by tentacles.
Sea anemones have a gastrovascular cavity that serves as stomach. This cavity has one opening both meant for mouth and anus.
Sea anemones are capable of changing their shape and lives on the mud, holding it by pedal disc.
Polychaetes are segmented worms. Each segment of the body bears parapodia. It helps them in locomotion. There are different types of polychaetes, tube-dwelling polychaetes are one of them.
Tube - dwelling polychaetes make tubes to protect their soft bodies.
They don't have parapodia but some special anterior structures for feeding. The tubes are made from calcareous materials.
