Quote #1
While his mother was alive, Yura did not know that his father had abandoned them long ago, had gone around various towns in Siberia and abroad, carousing and debauching, and that he had long ago squandered and thrown to the winds the millions of their fortune. (1.3.1)
While he's young, Zhivago doesn't understand that he has come from a rich family, because he's living only with his mother. His dad, on the other hand, is an irresponsible jerk who goes off and blows all the family money. What's kind of ironic, though, is that Zhivago grows up to abandon his own family, too, although the circumstances are a bit different.
Quote #2
Yura was always told that [his father] was in Petersburg or at some fair, most often the one in Irbit. (1.3.1)
Rather than tell Zhivago the truth about his father, his mother is always careful to lie and to say that his father has just gone away for a little while. It's kind of the Russian version of something like: "Your dad went out for cigarettes… five years ago."
Quote #3
Over the lawns in an auditory hallucination hung the phantom of his mother's voice; it sounded for him in the melodious turns of the birds and the buzzing of the bees. (1.6.2)
When his mother is gone, Zhivago continues to hear her voice wherever he goes, especially when he's out in nature. This just goes to show how strong a presence his mother was in his life. You could even argue that the guy spends the rest of his days trying to fill the hole left by his mom's death.
