Answer:
The original organism is called the <u><em>parent (ancestor)</em></u> , and new organisms are called the <u><em>offspring</em></u>.
Explanation:
Reproduction is one of the characteristics of life. Every living organism tends to give rise to another organism. The organism which gives rise to another organism is termed as the parent. The organism which is born is known as the offspring.
There are two basic methods of reproduction. An organism can give rise to another organism by the method of asexual or sexual reproduction.
During asexual reproduction, identical copies of the parent organism are made. During sexual reproduction, two organisms reproduce to produce non-identical offsprings.
Answer:
Punnett square is a square diagram which is used to predict the genotype of the offspring produced by particular cross.
Let P and p be the alleles of the gene responsible for the flower colors in a plant.
The genotype of both the parents is given as heterozygous that is, Pp.
Two types of gametes would be formed P and p.
The cross is shown in the image below.
The cross would be result in offspring with three types of genotypes PP, Pp and pp in 1:2:1.
Natural system is former when various components get grouped together for a particular function
<h2>Mutation & genetic drift</h2>
Explanation:
- A mutation is characterized as a lasting change to the DNA succession in a quality. This change moves the hereditary message conveyed by the quality and can modify the amino corrosive arrangement of the protein the quality encodes. This implies future cells created by the quality will just convey a specific characteristic.
- Genetic Drift is the change in the hereditary structure of a populace after some time because of possibility or irregular occasions. In instances of hereditary float, for example, catastrophic events or periods of irregular climate, the age that makes due to repeat won't really be the fittest, yet the most fortunate. Hereditary float doesn't allude to a particular change in hereditary cells, rather to arbitrary events that impact a population's genetic makeup.
- Hence, the right answer of the fill up the blank is "mutation and genetic drift".
