Because, the moon's gravitational pull.

The side of the earth that's facing the moon will have high tides, due to the gravitatonal pull.

That being said, the moon effects the tides because of the gravitational pull between the earth and moon.

Without the moon we wouldn't have tides, so the moon is very important.

High tides occur every 12 hours and 25 minutes.

It takes approximately six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.

hichkok12 [17]

Answer:

Considering the <u>whole progeny</u> (100%), there will be

  • 25% Black male kittens, XBY
  • 0% Calico Male kittens
  • 25% Calico female kittens, XBXR

Explanation:

<u>Available data:</u>

  • The gene for Calico (multicolored) cats is an x-linked trait and codominant
  • Calico Females receive a "B" and an "R" gene, and have black and orange splotches on white coats. Their genotype is XBXR.
  • Males can only be black or orange, but never calico. Their genotype is XBY and XRY

Cross: a female calico cat with a black male

Parentals)   XBXR    x    XBY

Gametes)  XB  XR       XB   Y

Punnett square)    XB        XR

                   XB   XBXB   XBXR

                    Y      XBY      XRY  

F1) Among the whole progeny:

  •     2/4 = 50%  will be black (female XBXB and male XBY)
  •     1/4  = 25% will be Calico (female XBXR)
  •     1/4  = 25% will be Orange (male XRY)  

   Among females:

  •    1/2 = 50% of females will be black, XBXB
  •    1/2 = 50% of females will be Calico, XBXR

   Among males:

  •    1/2 = 50% of males will be black, XBY
  •    1/2 = 50% of males will be orange, XRY
