### Step-by-Step Solution: 1. **Understanding Sex Determination in Humans**: - In humans, sex is determined by the combination of sex chromosomes. Males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). 2. **Gamete Formation**: - During gametogenesis, males produce two types of sperm: half carry the X chromosome and half carry the Y chromosome. Females, on the other hand, produce only one type of egg, which carries the X chromosome. ...

Most of the polyatomic molecules except a few such as CO_(2) and CS_(2) are linear or angular with a bond angle generally somewhat greater than 90^(@) A bond angle is defined as the angle between the direction of two covalent bonds Since the atoms in molecules are in constant motion with respect to each other they are not expected to have a fixed value of bond angle Repulsion between non-bonded atoms alone does not provide an adequate explanation Hybridisation of bonding orbitals an adequate explanation Hybridisation of bonding orbitals also plays a very important role in detrmining the value of bond angle It has been observed that in hybridisation as the s-character of hybrid orbital increases the bond angle increases In P_(4) molecule phosphorous atoms are tetrahedrally arranged The angle P-P-P in the molecule is .
