Gametes are said to have homologous chromosomes, if they have same genes arranged in same order.
During gamete formation meiosis precedes, therefore, individual gamete does not have its homologous counterpart. After fertilization, in diploid nucleus, homologous chromosomes are restored.
What else can I help you with?
When we see chiasmata under a microscope that lets us know the cell is in which phase?
Chiasmata are observed during the prophase I stage of meiosis. They represent the points where homologous chromosomes exchange genetic material through a process called crossing over. The presence of chiasmata indicates that homologous chromosomes are paired and undergoing genetic recombination, which is essential for genetic diversity in gametes.
A lion sperm has 18 chromosomes and a tiger egg has 33 chromosomes how they can be crossed?
Ligers are hybrid offspring of a male lion and a female tiger. They inherit 17 chromosomes from the lion and 16 chromosomes from the tiger, resulting in a total of 33 chromosomes. This is possible due to a phenomenon called chromosomal pairing during meiosis, where homologous chromosomes from each parent pair up and segregate into gametes.
What are statements that are true about chromosomes?
Selected Answer: The father donated one of each pair of homologous chromosomes, and the mother donated the other.
Mendel observed that pairs of alleles were separated or segregated in gametes and that they were rejoined in fertilization. We know that pairs of are segregated in and then are rejoined through fertil?
Mendel observed that pairs of alleles are segregated during meiosis, the process of gamete formation, where homologous chromosomes are separated into different gametes. During fertilization, these gametes combine, rejoining the alleles from each parent to form a new genotype in the offspring. This segregation and rejoining of alleles is fundamental to the inheritance of traits.
How many chromosomes did the parent cell have diploid or haploid?
To determine whether a parent cell is diploid or haploid, you need to know its chromosome number. A diploid cell contains two complete sets of chromosomes (one from each parent), while a haploid cell has only one set. For example, in humans, diploid cells have 46 chromosomes, while haploid gametes (sperm and eggs) have 23 chromosomes. Therefore, if the parent cell has 46 chromosomes, it is diploid; if it has 23, it is haploid.
A species has homologous chromosomes. what does this say about the species?
It has pairs of matching chromosomes (APEX)
How would you know if 2 chromosomes were homologous pairs?
Homologous chromosomes are similar in size, shape, and genes. They are typically present in pairs, one inherited from each parent. To determine if two chromosomes are homologous pairs, genetic analysis, such as karyotyping or DNA sequencing, can be performed to compare their structure and content.
Chromosomes line up into pairs called?
homologous chromosomes if you didn't know pay attention at school or MR.Capo

What genetic information can be identified easily with a karyotype?
The answer is,homologous chromosomes :) LOL hope that helped, even though i know it did ;)
How many matching pairs of chromosomes do humans have?
23 per cell except for gametes who have only have only have one of every chromosome. There are between 50 and 75 trillion cells in a human body. How many of them are gametes is something I wouldn't know.
What does disjunction mean?
Disjunction is a logical operation that connects two propositions with an "or" statement. It indicates that at least one of the propositions is true. So, if A or B is a disjunction, it means that either A is true, B is true, or both are true.
During which phase of meiosis do spindle fibers move the sister chromitatdes to the center of cells?
That would be anaphase I of meiosis. We know the question is concerning meiosis and not mitosis because it involves homologous chromosomes. Anaphase I begins when the kinetochore fibers stemming from the centrioles "grab" the centromeres of homologous chromosomes and "pull" them towards opposite ends of the cell.The mechanisms are a little more complicated than "grabbing" and "pulling," but for this question the mechanisms are of little importance.
What assorts independently during meiosis?
Genes assort independently if they are on different chromosomes. If a pair of genes are on the same chromosome, it depends on how far apart they are to determine the chances of them staying together or moving apart.
Which one of the following choices best describes the behavior of a tetrad during anaphase you of meiosis?
It is helpful to include what the following choices are so a person will know which is the correct answer. Without knowing what the following is it is hard to know which best describes the behavior of a tetrad during anaphase.
What determine the sexes of the child in human?
In human beings, the females have two X chromosomes and the males have one X and one Y chromosome. Therefore, the females are XX and the males are XY. The gametes, as we know, receive half of the chromosomes. The male gametes have 22 autosomes and either X or Y sex chromosome. Type of male gametes: 22+X OR 22+ Y. However, since the females have XX sex chromosomes, their gametes can only have X sex chromosome. Type of female gamete: 22+X Thus, the mother provides only X chromosomes. The sex of the baby is determined by the type of male gamete (X or Y) that fuses with the X chromosome of the female.
