If an Allium cell has 30 chromosomes before Mitosis how many chromosomes are present in each daughter cell?
both will have 30 chromosomes.
What are the specific names of autosomal chromosomes like sex chromosomes?
Y chromosome is autosomal dominant chromosome. When it is present, the sex of the child is male. When both the chromosomes are X, then the sex of the child is female. X chomosome is called as autosomal recessive chromosome.
Describe some of the pieces of information that scientists discovered that contributed to the chromosome theory of inheritance?
At around 1900, biologists began to see parallels between the behavior of chromosomes and the behavior of Mendel's "factors" during sexual life cycles. They knew that chromosomes and genes are both present in pairs in diploid cells (Cells with 2n chromosomes, in humans n is 23), homologous chromosomes separate and alleles segregate during meiosis, and fertilization restores the paired condition for both chromosomes and genes. Hence the Chromosome Theory of Inheritance. Source: AP Biology Textbook by Campbell Reece
Both meiosis and fertilization are essential to maintain chromosome number constant .why?
Total number of chromosomes remain same in same species of organism through meiosis process. In meiosis process the number of chromosomes are reduced to half as a result in gametes only one set of chromosomes will be present. In this process chromosomes are same.....
The offspring will have traits of both the mother and father Why?
during fertilization 23 chromosomes are coming from mother and 23 are coming from father and so a diploid condition is establishes in the zygote
If an Allium cell has 30 chromosomes before Mitosis how many chromosomes are present in each daughter cell?
both will have 30 chromosomes.
How many chromosomes are present in a mature sex cell if the immature sex cell contains 18 chromosomes?
both produce mature sex cells.
What are the specific names of autosomal chromosomes like sex chromosomes?
Y chromosome is autosomal dominant chromosome. When it is present, the sex of the child is male. When both the chromosomes are X, then the sex of the child is female. X chomosome is called as autosomal recessive chromosome.
What is a good sentence with the word Homozygous?
A cell is said to be homozygous for a particular gene when identical alleles of the gene are present on both homologous chromosomes.

What are similarities between prokarytic and eukarytic chromosomes?
they are both chromosomes
How do you use homozygous in a sentence?
An organism is homozygous for a particular gene when identical alleles of the gene are present on both homologous chromosomes. (see related link)

What sex chromosomes are found in males?
Males have both X & Y chromosomes
Are chromosomes found in animal cell or plant cell?
Both, chromosomes are found in most eukaryotic cells.
How are mitosis and meosis alike?
Because they are division of something. Meiosis is the division of chromosomes and mitosis is the division of cells.
