No, a female kangaroo cannot determine the sex of its offspring before giving birth. The sex of the joey is determined by the chromosomes contributed by the male kangaroo during fertilization. However, once the joey is born, the mother can influence its development through factors like nutrition and environmental conditions, but she does not have control over the sex of the offspring.

The sex chromosomes, X and Y, determine the gender of one's offspring. An X and a Y is a boy, and 2 X's is a girl.
X and Y chromosoms determine whether or not an offspring is a male or female. Chromosomes come in pairs. Boys have an X and a Y chromosome pair; girls have an X and an X chromosome pair.

Men do they are the carriers of the X and Y chromosome. Girls only have X chromosomes. Two X chromosomes mean it will be a girl and a X and a Y mean it will be a boy.
