Answer:

The child must have a father who is colorblind and a mother who is a carrier/ is colorblind.

Explanation:

The genetic code for color blindness is carried upon the x chromosome. This means that a male- who has only one X chromosome- only needs their mother to be a carrier to be colorblind. Women on the other hand, need two to be color blind, as the faulty x chromosome can be weeded out by the other.

Therefore, the father, in order to pass on the colorblindness, must be colorblind himself, whereas the mother only needs to be a carrier (or can be completely color blind herself).

Explanation:

A) The mother is a heterozygous carrier.   - only one that makes sense

B) The father is a heterozygous carrier.  - he is double recessive

C) The mother cannot have the colorblind gene. - that is possible

D) The mother is homozygous dominant for normal vision. - that would mean the 100% of the offspring would be normal

Which statement best describes a cause and its effect during the process or muscle contraction?​
Alisiya [41]

Answer. The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.
