The egg chromosome number of a guinea pig is 32, as guinea pigs have a diploid chromosome number of 64. This means that each gamete, including the egg, contains half of the total chromosome number. Thus, guinea pig eggs are haploid, containing 32 chromosomes.
haploid.

The sperm gamete determines the gender of the offspring in humans. Sperm carries either an X or a Y sex chromosome, while the egg always contains an X chromosome. If a sperm with an X chromosome fertilizes the egg, the offspring will be female (XX). If a sperm with a Y chromosome fertilizes the egg, the offspring will be male (XY).
The sex chromosome typically carried by an ovum is X-chromosome. The sperm may carry either x or y sex chromosome.
When each chromosome is present once, not as a pair, it is called a haploid state. This is typically seen in gametes (sperm and egg cells) in sexually reproducing organisms, where the chromosome number is half that of the diploid state, which contains pairs of chromosomes. In humans, for example, haploid cells have 23 chromosomes, while diploid cells have 46.
That depends on the species. In the case of humans, egg and sperm cells have half of the chromosomes of a regular cell - 23 chromosomes each. When they join, the resulting cell will have the complete 46 chromosomes.
Yes.
An egg can only carry an X chromosome. In normal cases, it only carries one. The sperm carries either one X or one Y chromosome.
No, the male decides the gender of the calf. When the semen meets the egg, if it contains a Y chromosome it is going to be a bull (male) calf because the mother will have provided the X chromosome. Whereas, if the semen that contained an X chromosome fertilized the egg then the result would be a heifer (female) calf.
