telo118 [61]

Answer:

<h2>(14+16)/1000 *100= 3</h2>

Explanation:

Parental combinations are always more common then other recombinant progenies.

A female fly is heterozygous for three X-linked genes crossed with an abc/Y male. . If single crossover occurs between a & b  and between b & c, then the double cross is that, which occurs in both.

Double cross over progeny are always least in number, so here double cross occurs are in abC 14 and ABc 16.

So we are expecting that number of double cross over progeny= (14+16)/1000 *100= 3

Flauer [41]

Answer:

Totipotent Stem Cells - They can differentiate into any type of human body cell or the placenta.

Example: Fertilized egg cells.

Pluripotent Stem Cells are from totipotent cells and can differentiate into any cell in the human body; however, not many are in the placenta.

Example: Blastocyst cells.

Multipotent Stem Cells - They can only differentiate into closely related cells.

Example: Blood stem cell

Unipotent Stem Cells - They can only produce their type of cell.

Example: Skin stem cells (which can only become a new skin stem cell).
