Meiosis ensures the transmission of traits from one generation to the next. at the same time, it is a key process that introduces genetic variation into the traits that offspring inherit from their parents. in this tutorial, you will explore the genetic context of meiosis. this diagram shows a diploid nucleus (2n=8) in which chromosome replication has occurred in preparation for mitosis (top) and meiosis (bottom). the nucleus at top right is now in prophase of mitosis; the nucleus at bottom right is now in prophase i of meiosis. in the life cycle of an organism, meiosis is paired with the process of fertilization. understanding the life cycle of an organism is the key to understanding how sexual reproduction ensures the inheritance of traits from both parents and also introduces genetic variation. meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or: from parental cells with two chromosome sets (diploid or 2n).

See the explanation below, what is the question you intend to ask anyway?

Explanation:

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
