Say that the dominant gene is represented by B and the recessive gene is represented by b the combinations if using the Punnett square would be BB, Bb, Bb, and bb so 4 possible combinations and 3 possible nonrepetitive combinations- BB, Bb, and bb
I think you look to Genetics, DNA and Heredity . MALES and FEMALES . Women have 46 chromosomes ( 44 autosomes plus two copies of the X chromosome ) in their body cells. They have half of this or 22 autosomes plus an X chromosome in their egg cells. Men have 46 chromosomes ( 44 autosomes plus an X and a Y chromsomes ) in their body cells and have half of these 22 autosomes plus an X or Y chromosome in their sperm cells. when the egg joins with the sperm , the resultant baby has 46 chromosomes ( with either an XX in a female baby or XY in a male baby ).
Weight must not be confused with the mass of an object which is a fundamental property of the object expressed in kilogram (kg). Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth.
