Homework Answers
Answer: Option(e) is correct
Explanation: As we know that the X chromosome is shorter in length as compaired to Y chromosome. In the sex chromosome the X and Y chromosome there were present homologous chromosome at one point long million years ago. These X and Y chromosomes are the 23rd pair of autosomes. but ovr the last several million years the Y chromosome has began degenerating that is it is literally falling apart. So in the certain region of X and Y chromosome there is still homology or similar genes which is found in similar location which is known as Pseudo autosomal region(PAR) responsible for translocation.

Amounts of which of the components of cell cycle regulation vary with cell cycle phase? Cyclin-dependent kinases Cyclins Checkpoints Kinetochores The synaptonemal complex forms to facilitate pairing of homologous chromosomes during prophase of mitosis and meiosis. prophase of meiosis I and II. c. prophase of meiosis I only. d. all stages of meiosis. Mendel’s Second Law of Independent Assortment refers to the separation of two identical alleles of the same gene. two different alleles of the same gene. alleles...

In placental mammals, either the maternal or paternal X chromosome is inactivated, by chance. Each is equally likely to be inactivated. However, there is an evolutionary conflict. The chromosomes “compete” against each other. It would be in the evolutionary interests of each parent to inactivate the chromosome from the other parent. In placentals, the two sexes have evolved to a draw, and both chromosomes become inactivated (the idea of selfish genes and chromosomes is covered in more detail in Evolution)....

A. Organisms heterozygous for inversions and translocations are
viable and able to produce progeny but usually in fewer numbers.
Explain why this is so in general terms.
B. Also, explain how would you distinguish among pericentric
inversions, paracentric inverisons, reciprocal translocations and
non reciprocal translocations as sources of semi-sterility. You
need to consider meiotic figures.
C. How can these chromosome aberrations be used to map genes to
chromosomes or linkage groups. You may use a two-point mapping
system as an...

1 points Saved Robertsonian translocations are better described by which of the following? A. transfer of nuclear genes into mitochondria o B. the fusion of two small chromosomes end-to-end such that a double centromere occurs C, unequal crossing-over during meiosis D. a part of one chromosome becomes attached to a non-homologous chromosome E. breaks at or near the centromeres of two acrocentric chromosomes followed by the reciprocal exchange of broken parts

A cell undergoing meiosis has four pairs of homologous chromosomes. How many different combinations of maternal and paternal chromosomes are possible within the daughter cells that form? (Do not consider crossing over in your answer.) a.16 b. 8 c. 4 d. 2

Translocation mutations can happen to entire chromosomes – as happened in the ancestral species of the human lineage, giving us one less chromosome pair than our closest extant primate relatives (the chimps, gorillas, and orangutans). A far more extreme example of chromosome-number reduction due to translocations and fusions discussed in your textbook is ________. a. the seedless-watermelon cultivar b. the white Dutch rabbit species, whose members were entirely black before the occurrence of multiple translocation mutations c. the Indian muntjac...

An organism has a diploid chromosome number of 8. The paternal chromosomes differ from the maternal ones. If no crossing over occurs, how many different gametes are possible? If a couple has 4 boys, what is the probability that the fifth child will be a boy? You have performed some experiments, collected data, and calculated the chi-square values for 2 data sets. (The degrees of freedom = 1 for both data sets.) The calculated chi-square value for data set #1...
