Answer from: qveenl

The answer would be: A.50%

A child will get genetic material from both parents, half from the father and half from the mother. This is why the gamete cells (sperm/ovum) are made from meiosis and only have 50% of the original genetic material.
In this case, the parent carries a deletion on one of the two homologous chromosomes. Since the gamete only has one of the chromosomes, half of the gamete of this parent would have the defective chromosome and the other half have a normal chromosome. So, the chance for the child to inherit the defective gene is 50%.

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 !
