Michael is color-blind. his gene for color blindness is most likely a

The right answer is: recessive gene on his X chromosome.

The structure of visual pigments is coded by three genes whose pathology modifies pigments and determines color blindness. The two genes coding for the L-cone and M-cone pigments are located on the long arm of the X chromosome.

Since it's a recessive disease. In the female, carrying two X chromosomes, the genes are in duplicate, while in humans, the carrier of a single X chromosome, the gene is in single copy and its color vision is determined solely by the X chromosome received from its mother.

An X chromosome can be pathological in two ways: either because one of the genes is abnormal or because it is absent.

d i think its   answer d

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 !
