Answer:
a: metaphase
Explanation:
the chromosomes are aligned at the metaphase plate
Answer:
The correct answer will be-
1. Law of inheritance
2. Law of Independent Assortment
3. Meiosis
Explanation:
Gregor Mendel is known for his work on the pea plants to study the pattern of inheritance of traits in a population.
On the basis of his work, Laws of inheritance were proposed in which the main three laws were the Law of dominance, Laws of segregation and law of independent assortment.
The Law of inheritance suggested that factor (genes) responsible for a trait come in pairs and is inherited one from each parent to the offspring.
The law of Independent Assortment stated that these genes segregate and passed on to the offspring independent of each other.
The cell division associated with the formation of a germ cell is known as meiosis which produced four daughter cells with different genetic material.
Answer: Plant because they survive by water and sunlight.
Explanation:
Germ cells produced gametes and are only cells that undergo meiosis as well as mitosis. Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis.
Answer:
Mutations rarely occur
Explanation:
Mutations are genetic changes, i.e., alterations in the DNA sequence. Generally, mutations have deleterious effects, but there are exceptions where mutations may confer an adaptive advantage in a given environment. Mutations are often deleterious, and thereby these genetic changes are rare events. In consequence, mutation rates, i.e., the frequency by which new mutations arise in an organism over time, are generally very low. Finally, mutations that arise only in germ cells can be inherited from a generation to the next generation, while somatic mutations cannot be inherited.
