Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
Step by step
Solved in 2 steps
- In meiosis, we talk about the daughter cells having half the chromosomes of the parent cell. Choose the option that best describes what is happening to end up with half the number of chromosomes in the daughter cells. Question 8Answer a. All of the chromosomes are chemically cut in half so the daughter cells get the top or the bottom half of each of the chromosomes. b. Each daughter cell has one chromosome from each of the homologous pairs found in the parent cell. c. Each daughter cells gets a random set of chromosomes that add up to half the number of chromosomes as the parent cells had..A sexually reproducing organism has the following phenotype DdEeAaTt: The D and E loci are on the same arm of a metacentric chromosome in cis configuration. The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. There are no other chromosomes. Using diagrams, show a cell at metaphase of mitosis and show the results of mitosis. Ensure you show the location of the gene loci on the different chromosomes.Rose plants are octoploid (octo = 8). Gametes from a rose plant contain 40 chromosomes. Indicate which of the following are TRUE statements. Select 3 correct answer(s) The gametes from a rose plant are diploid. The basic chromosome number of a rose plant cell is 40. The number of chromatids in a rose plant cell at G2 of the cell cycle is 160. The number of chromatids in a rose plant cell at G2 of the cell cycle is 80. The gametes from a rose plant are tetraploid. The basic chromosome number of a rose plant cell is 10. Rose plants are aneuploid.
- Think about the same two genes that were mentioned in Question 23—R and T, present in the heterozygous condition as R and r, T and t. Now imagine that the gene for flower color (the alleles R and r) is not on the same chromosome as the gene for plant height (the alleles T and t). Because the two genes are on separate chromosomes, they show independent assortment. What does that mean? When this nucleus undergoes meiosis, it can make gametes with four different genotypes. Why? A very important aspect is that the four different genotypes will be formed in almost exactly equal numbers. Why?Hi, I'm having some trouble with this practice problem from my study guide. If anyone can explain it it would be very helpful! Sometimes nondisjunction will occur in a parent that has normal chromosome numbers and result in an offspring that has abnormal number of chromosomes. The phenotype of the affected offspring will often allow geneticists to determine in which parent and during which division of meiosis the nondisjunction occurred. In each of the examples below, assume the parents have a normal diploid chromosome complement. A man with the X-linked dominant condition “brown tooth enamel” and a woman with normal tooth enamel produce a son with brown tooth enamel. Let’s call the allele for brown tooth enamel “XB” and normal tooth enamel “Xb”. EXAMPLE 1: The parents in the family above produce another son, this time with two Y chromosomes and normal tooth enamel. In which parent did the nondisjunction occur? Explain and/or illustrate. Did nondisjunction occur at meiosis I or II?…Hi, I'm having some trouble with this practice problem from my study guide. If anyone can explain it it would be very helpful!

- A sexually reproducing organism has the following phenotype DdEeAaTt: The D and E loci are on the same arm of a metacentric chromosome in cis configuration. The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. There are no other chromosomes. 1. What is the haploid number of this organism? 2. Using diagrams, show a cell at metaphase of mitosis and show the results of mitosis. Ensure you show the location of the gene loci on the different chromosomes.Diploid vs. Haploid: Given 2n = 30a. Haploid (n) number? b. This organism has a total of how many chromosomes? c. How many different pairs of chromosomes does this organismhave?In mammals, there are two sex chromosomes, X and Y, which behave like homologous chromosomes during meiosis. Normal males have one X chromosome and one Y chromosome, and normal females have two X chromosomes. Males with an extra Y chromosome (XYY) occasionally are found due to inappropriate segregation of the chromosomes (i.e. non-disjunction). Which of the following could give rise to such an XYY male? Answer Yes or No for each situation. nondisjunction in the first meiotic division of spermatogenesis; normal meiosis in the mother nondisjunction in the second meiotic division of spermatogenesis; normal meiosis in the mother nondisjunction in the first meiotic division of oogenesis; normal meiosis in the father nondisjunction in the second meiotic division of oogenesis; normal meiosis in the father
- In mice, 2n = 40. If a mouse cell divides by mitosis, it will produce two daughter cells that each have ________ chromosomes. If a mouse cell divides by meiosis, it will produce four daughter cells that each have ________ chromosomes. Type the appropriate number to fill in each blank (e.g., 40).An equational division of mitosis is occuring for a diploid organism that has three heterologous chromosomes. One acrocentric, one metacentric and one telocentric. The organism is tetrahybrid and heterozygous for dominant and recessive alleles at four different loci. The parental genotypes were AAbbCCDD and aaBBccdd. Locus A and B are on the telocentric chromosome. Locus C is on a metacentric chromosome. Locus D is on the acrocentric chromosome. Part A: How many chromosomes are observed during anaphase? Part B: For cells of this organism that undergo meiosis, how many tetrads are observed during metaphase I? Part C: What is the n value for this organism?An equational division of mitosis is occuring for a diploid organism that has three heterologous chromosomes.
