How is genetic variation among gamete produced during meiosis?
Genetic variation among gametes is produced during meiosis through processes such as crossing over (exchange of genetic material between homologous chromosomes), independent assortment (random orientation of homologous chromosomes), and random fertilization (combining of different gametes). These mechanisms shuffle and mix genetic material from the parents, leading to new combinations of alleles in the gametes and promoting genetic diversity.
How do sister chromatids differ from homolohous chromosomes?
Sister chromatids are exact copies of each other produced during DNA replication in a cell, connected at the centromere. Homologous chromosomes are pairs of chromosomes that carry the same genes in the same location, but may have different alleles. Sister chromatids are produced in preparation for cell division, while homologous chromosomes are inherited from each parent.
What is the difference between sister and non sister chromatids?
Sister chromatids are those replicated from the same chromosome whereas non-sister chromatids may be found in meiosis (particularly metaphase II) where paternal and maternal chromatids line up and eventually separate at the metaphase plate.
Which combination of gametes in humans will result in an individual who is male?
A male individual is produced when a sperm carrying a Y chromosome fertilizes an egg carrying an X chromosome.
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.
What is an original chromosome and its copy called?
An original chromosome is called a homologous chromosome, and its copy is called a sister chromatid. Homologous chromosomes have the same genes in the same order but may have different alleles, while sister chromatids are identical copies produced during DNA replication.
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.
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).

What chromosome did the father contribute a normal female is produced?
The father must have contributed an X chromosome if a normal female is produced.
What chromosome did the father contribute if the normal females produced?
The father must have contributed an X chromosome if a normal female is produced.
Why the chromosomes in the haploid cells that are produced by meiosis 1 look different from those produced by meiosis 2?
The chromosomes in haploid cells produced by meiosis I look different from those produced by meiosis II primarily due to genetic recombination and the reduction of chromosome number. During meiosis I, homologous chromosomes are separated and can undergo crossing over, resulting in genetic variation. In contrast, meiosis II resembles mitosis, where sister chromatids are separated, leading to the production of haploid cells that contain single chromatids. Thus, the genetic makeup of the cells differs due to the events of meiosis I.
Is the chromosome number of a tapworm produced by budding haploid or diploid?
The chromosome number of a tapeworm produced by budding is diploid. This means that the tapeworm has two sets of chromosomes in its cells.
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.
