Kuliev and Verlinsky (2004) state that there was a relatively high number of separation errors at meiosis I. In these cases the centromere underwent a premature division, occurring at meiosis I rather than meiosis II. Regarding chromosome 21, what would you expect to be the chromosome 21 complement in the secondary oocyte in which you saw a single chromatid (monad) for chromosome 21 in the first polar body? If this secondary oocyte was involved in fertilization, what would be the expected consequences?
The kidney bean plant, Phaseolus vulgaris, is a diploid speciescontaining a total of 22 chromosomes in somatic cells. Howmany possible types of trisomic individuals could be producedin this species?
. With regards to the grasshopper testes experiment, diakinesis is an ideal stage to determine chromosome number due to the degree of condensation of the chromosomes? Count the chromosomes at this stage. Does it represent a diploid or a haploid number?
The dog Canis familiaris is a diploid organism with 39 pairs of homologous chromosomes. What is the 2n number for the dog? What is the n number for the dog?
The mouse haploid genome contains about 2.9 × 109 nucleotide pairs of DNA. Indicate how many nucleotide pairs of DNA are present in each of the following mouse cells: (a) somatic cell, (b) sperm cell, (c) fertilized egg,(d) primary oocyte, (e) first polar body, (f) secondary spermatocyte.
The normal sequence of nine genes on a certainDrosophila chromosome is 123 • 456789, where the dotrepresents the centromere. Some fruit flies were foundto have aberrant chromosomes with the followingstructures:a. 123 • 476589 c. 1654 • 32789b. 123 • 46789 d. 123 • 4566789Name each type of chromosomal rearrangement, anddraw diagrams to show how each would synapse withthe normal chromosome.
What is the approximate location of the centromereon human chromosome 7?
The human genome consists of 23 pairs of chro-mosomes (22 pairs of autosomes and one pair of sex chro-mosomes). During meiosis, the maternal and paternal setsof homologs pair, and then are separated into gametes, sothat each contains 23 chromosomes. If you assume thatthe chromosomes in the paired homologs are randomlyassorted to daughter cells, how many potential combina-tions of paternal and maternal homologs can be gener-ated during meiosis? (For the purposes of this calculation,assume that no recombination occurs.)
A wild-type chromosome has the following segments: A B C • D E F G H I Researchers have found individuals that are heterozygous for each of the following chromosome mutations. For each mutation, sketch how the wild-type and mutated chromosomes would pair in prophase I of meiosis, showing all chromosome strands. a. A B C • D E F D E F G H I b. A B C • D H I c. A B C • D G F E H I d. A B E D • C F G H I
A sperm cell from the fruit fly Drosophila melanogaster contains four chromosomes. How many chromosomes would be present in a spermatogonial cell about to enter meiosis? How many chromatids would be present in a spermatogo- nial cell at metaphase I of meiosis? How many would be present at metaphase II?
A heterozygous reciprocal translocation involving 2 non-homologous chromosomes resulted to a new sequence ABCDXYZ and TUVWEFG. Illustrate the chromosomes before and after translocation and the pachytene configuration of the chromosome after translocation.
On rare occasions, people are born with a condition known as uniparental disomy. It happens when an individual inherits both copies of achromosome from one parent and no copies from the other parent. Thisoccurs when two abnormal gametes happen to complement each otherto produce a diploid zygote. For example, an abnormal sperm thatlacks chromosome 15 could fertilize an egg that contains two copies ofchromosome 15. In this situation, the individual has maternal uniparental disomy 15 because both copies of chromosome 15 were inheritedfrom the mother. Alternatively, an abnormal sperm with two copies ofchromosome 15 could fertilize an egg with no copies. This is known aspaternal uniparental disomy 15. If a female is born with paternal uniparental disomy 15, would you expect her to be phenotypically normal,have Angelman syndrome (AS), or have Prader-Willi syndrome(PWS)? Explain. Would you expect her to produce normal offspring oroffspring affected with AS or PWS?
