Female mammals have two X chromosomes in a diploid set and thus only produce homogametes, all of which have only X sex chromosomes. Males produce heterogametes, as they have one X and one Y sex chromosome in a diploid set. Half of a male's sperm cells contain X and half contain Y chromosomes.
What else can I help you with?
How sex of embryo can be determined?
By taking the DNA of the embryo, putting it through some tests and coming out with results on whether it's a female (XX chromosomes) or a male (XY chromosomes). These chromosomes are the same in terms of sex selection for all mammals.
Chromosomes of a pair of homologous chromosomes may differ from other chromosomes in terms of?
Homologous chromosomes are similar in size, shape, and genetic content. They may differ from other chromosomes in the genome in terms of the specific alleles they carry at corresponding gene loci. These differences in allele sequences can result in variations in traits or genetic disorders.
What is the difference between males and females in terms of their chromosomes?
Male is XY , female is XX .
What is distinctive of mammals?
Mammals have internal breeding and have sexual intercourse in order to fertalize the eggs. Other animals have external breeding where the female lays the eggs and then the male fertilizes it. In simpler terms, Mammals have sex, and other animals don't.
What is the opposite gender of a dog?
There is the female dog (bitch) and the male dog (bastard OR stud), what the genders are in breeding terms.
How does meiosis differ from mitosis in terms of the process of cell division?
Meiosis is a type of cell division that produces sex cells with half the number of chromosomes, while mitosis is a type of cell division that produces identical cells with the same number of chromosomes as the parent cell.
What are the sex chromosomes for the male and female?
X and Y chromosomes contain the genes that will determine a persons sex. The pairing of the two that will allow the person to be a male is (X,Y) and if the person is to be a female the pattern will be (X,X). In terms of size the (Y) chromosomes is smaller than the (X) but the over all shape of the chromosomes are the same.
How does mitosis differ from meiosis in terms of chromosome segregation?
In mitosis, chromosomes are duplicated and then segregated into two identical daughter cells, resulting in cells with the same number of chromosomes as the parent cell. In meiosis, chromosomes are duplicated but then segregated twice, resulting in four daughter cells with half the number of chromosomes as the parent cell.
What is the difference between karyogram and karyotype?
A karyogram is a photograph of an individual's chromosomes arranged in a standard format, while a karyotype is the set of chromosomes found within the nucleus of a eukaryotic cell. In simpler terms, the karyogram is the visual representation of the karyotype.
How does meiosis 1 differ from mitosis in terms of the process of cell division?
In meiosis 1, the cell divides twice to produce four daughter cells with half the number of chromosomes, while in mitosis, the cell divides once to produce two daughter cells with the same number of chromosomes as the parent cell.
What are the female organ of the plant part that produces egg cell?
I think in botanical terms it the ovum, in mammals the ovaries.
