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

AysviL [449]
The correct answer is true. Both intramembranous ossification and endochondral ossification originates from a primary ossification center. The primary ossification center, as the name implies, is the focus where the bone tissue starts ossifying. Primary ossification centers are usually found in the diaphysis of long bones or in the body of irregular bones.
