A woman with type A blood has a child with type A blood. Which of the following men could NOT be the father

B. All males could be the father

Explanation:

A woman with type A blood either has the genotype AA or Ai. A child with type A blood will also either have AA or Ai.

Type B blood is BB or Bi. Type AB blood is AB. Type O is ii.

To find out the men not be the father, you have to do Punnett squares between the mother and father.

AA mother with BB father - type AB child

AA mother with Bi father - type AB and type A child

Ai mother with BB father - type AB and type B child

Ai mother with Bi father - type AB, type B, type A, and type O child

AA mother with AA father - type A child

AA mother with Ai father - type A child

Ai mother with AA father - type A child

Ai mother with Ai father - type A and type O child

AA mother with AB father - type AB and type A child

Ai mother with AB father - type AB, type A, and type B child

According to these crosses, all males could be the father. The father with type B blood must have the genotype Bi. The father with type A blood can have either genotype AA or Ai. The father with type AB blood will always produce a type A child except with a woman who has the genotype BB for type B blood.

Hope that helps.

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 !
