An SSLP Is Located 2 Map Units Away from the X-Linked

question 28

Multiple Choice

An SSLP is located 2 map units away from the X-linked locus responsible for red-green color blindness.Three alleles of this SSLP are known: "4 repeats," "5 repeats," and "7 repeats." A woman with normal color vision,but whose father is color blind,marries a man with normal vision,and they have a son. $\begin{array}{|l|l|l|l}\hline \begin{array}{l}\text { Family } \\\text { member }\end{array} & \text { SSLP genotype } & \text { Family member } & \text { SSLP genotype } \\\hline \begin{array}{l}\text { Woman's } \\\text { father }\end{array} & \text { "5 repeats" } & \text { Woman's husband } & \text { "3 repeats" } \\\hline \text { Woman } & \begin{array}{l}\text { "5 repeats"/"7 } \\\text { repeats" }\end{array} & \text { Couple's child } & \text { "5 repeats" }\\\hline \end{array}$
Given the SSLP genotypes of the family members shown above,what is the probability that the couple's son is color blind?

• A)2%
• B)50%
• C)98%
• D)99%
• E)100%

Osteocytes

Mature bone cells that maintain bone tissue by regulating mineral content and assisting in the repair of damaged bone.

Interstitial Lamellae

Layers of bone matrix in compact bone that fill the spaces between osteons, providing strength and support.

Concentric Lamellae

Circular layers of bone matrix that surround the central canal within osteons, characteristic of compact bone structure.
