What are the differences between homologous chromosomes and chromosomes?
Homologous chromosomes are a set of chromosome pairs, one set maternal and the other paternal, that pair up during meiosis, the production of reproductive cells. The pairs have the same genes in the same locations, though once spread out the different pairs segregate out. the biggest way that these chromosomes change up is by exchanging lengths of the material.
If a cell with 40 chromosomes undergoes mitosis each of the daughter cells will have chromosomes.?
Meiosis results in gametes that have half the number of chromosomes of other cells. A gamete carries one of each pair of homologous chromosomes. Their are 46 chromosoes in Meiosis I and 23 in Meiosis II.
Why don't sex cells have homologous pairs of chromosomes?
you need one chromosome from one parent and one from the other parent. These homologous pairs each have the same genes but different alleles. For instance, one may code for black hair while the other codes for brown hair. You need both to be present in order to have both the parents traits.
How can a human with 47 chromosomes be produced?
This occurs due to nondisjunction, in which one or more homologous pairs of chromosomes do not separate during anaphase I, or sister chromatids do not separate properly during anaphase II of meiosis. The resulting daughter cells (gametes) will have either 22 or 24 chromosomes. If the gamete with 22 chromosomes unites with a normal gamete with 23 chromosomes, the offspring will have 45 chromosomes (23 + 22). If the gamete with 24 chromosomes unites with a normal gamete, the offspring will have 47 chromosomes (23 + 24). These are usually lethal conditions.
How many chromosomes are in each sperm produced by a male?
There are 23 chromosomes in each sperm produced by a human male.
How is genetic variation among gamete produced during meiosis?
Crossing over when pieces of homologous chromosomes are exchanged
Suppose that two alleles on one homologous chromosome are A and B and the other homologous chromosomes's alleles are a and b How many different genetic types of gametes would be produced without cro?

Why does a sex cell normally does not receive both chromosomes from a pair?
Homologous chromosomes are separated in anaphase I and then in anaphse II the chromosomes are separated into their chromatids. This results in 4 cells being produced with half the chromosome number (haploid).

How many homologous chromosomes do you have in your gametes?
Number of Homologous Chromosomes in GametesGametes contain 23 paired chromosomes. Gametes are haploid because they are sex cells to be combined with other haploid sex cells of the opposite gender to form the required 46 chromosomes that form a zygote (a future child), which is diploid.

How are karyotypes contructed?
A cell karyotype is produced by looking at chromosomes through a light microscope. A karyotype is produced by factoring in the length of individual chromosomes under the microscope, as well as their banding pattern, position of centromeres, and other physical characteristics.
A trait produced from two alleles that are alike is?
A trait that is produced from two alleles is a Homologous.
