Answer:
The correct answer will be- Meiosis I, anaphase I
Explanation:
Alleles are the variant alternative forms of a gene which determines the trait of an organism. The trait or phenotype is expressed only when the two alleles controlling a single trait on separate chromosomes are aligned in a complementary position.
During gamete formation, the alleles controlling a trait segregate independently of each other. This segregation of alleles takes place during Anaphase I of meiosis I. During anaphase, the sister chromatids are separated by the mitotic spindles so that the chromosomes can reach the opposite poles.
Thus, Meiosis I, anaphase I am the correct answer.
Answer:
Chromosomes contain genes, which help to determine an organism's traits. Genes come in alternate forms called alleles. The actual gene combination that an organism receives from its parents is called its genotype, while the trait that gets expressed as a result is referred to as its phenotype. If an offspring receives the same type of allele for a given gene from each parent, it is said to be h o m o z y g o u s. If the alleles differ, it is h e t e r o z y g o u s.

Explanation:
<em>Plants adapt to environmental stress by altering their metabolism, flowering, growth, and reproduction; and by migrating toward areas with more favorable climatic conditions.</em>

Answer:
Variations Within Ecosystems
Ecosystem diversity can be described as a term which is used o describe the changes within an ecosystem and the impact these changes have on the environment and humans.
Variations within an ecosystem can cause genetic drifts. Variations will cause those organisms to survive which are better adapted to survive to the changes which occur in an ecosystem. And the organisms which are not better suited become extinct over a period of time. Hence, this will lead to a wide rise in biodiversity.
