Chromosome Number Test 3 - Quiz

Welcome back to the Electronic Frontier science classroom of the 21st Century. This test has been designed to test your knowledge on the haploid (n) and diploid (2n) number of chromosomes found various animal, plant, and prokaryotic cells. The actual number of chromosomes will vary with the individual species.
I hope you do well and earn high grades on learning about chromosomes and organisms. !

  • 4. 

    How many haploid chromosomes are found in black mulberry (Morus nigra) gametes?  (Please enter a number from 2 - 500.)

    Correct Answer
    154
    Explanation
    Black mulberry (Morus nigra) is a diploid plant species, meaning it has two sets of chromosomes. In gametes, which are reproductive cells, only one set of chromosomes is present. Therefore, the number of haploid chromosomes in black mulberry gametes is equal to the number of chromosomes in one set, which is 154.

    How many diploid chromosomes are found in the Camelus dromedarius skin cells?  (Please enter a number from 2 - 500.)

    Correct Answer
    70
    Explanation
    Camelus dromedarius, also known as the dromedary or Arabian camel, is a species of camel. Like most mammals, dromedaries have diploid cells, which means they have two sets of chromosomes. The diploid number of chromosomes in the skin cells of a Camelus dromedarius is 70.

    What is the chromosome number in sperm cells of a donkey (Equus asimus)?

    • A.

      31

    • B.

      11

    • C.

      62

    • D.

      124

    Correct Answer
    C. 62
    Explanation
    The correct answer is 62 because donkeys, like most mammals, have a diploid chromosome number of 62. This means that each somatic cell in a donkey's body contains 62 chromosomes, with half coming from the mother and half from the father. However, sperm cells are haploid, meaning they only contain half the number of chromosomes as somatic cells. Therefore, the chromosome number in sperm cells of a donkey is 62.

      Honey bee

    • E.

      Plum

    Correct Answer
    D. Honey bee
    Explanation
    The honey bee has more than 48 chromosomes. This is because the question states that all the species listed have a total of 48 chromosomes in their somatic cells, except for one. Therefore, the honey bee must have a higher number of chromosomes than 48.

    Hydra vulgaris has (lower, same, higher) number of diploid chromosome number as humans.

    Correct Answer
    lower
    Explanation
    Hydra vulgaris has a lower number of diploid chromosome number compared to humans. This means that Hydra vulgaris has fewer pairs of chromosomes in its cells compared to humans. Chromosomes carry genetic information and determine various traits and characteristics. The difference in chromosome number between Hydra vulgaris and humans suggests a variation in their genetic makeup and evolutionary history.

    How many chromosomes are found in the sex cells of a male Mus musculus?

    • A.

      10

    • B.

      20

    • C.

      40

    • D.

      80

    Correct Answer
    B. 20
    Explanation
    Male Mus musculus, commonly known as a mouse, has 20 chromosomes in its sex cells. Sex cells, also known as gametes, are sperm cells in males. These cells are responsible for carrying genetic information to the offspring during reproduction. In mice, like many other mammals, the sex cells contain half the number of chromosomes compared to other cells in the body. Since the question specifically asks about the sex cells of a male Mus musculus, the correct answer is 20 chromosomes.

    How many diploid chromosomes are found in these organisms; hyacinth, newt, common oak, and scarlet oak?  (Please enter a number from 1 to 100.)

    Correct Answer
    24
    Explanation
    The answer is 24 because diploid organisms have two sets of chromosomes, one from each parent. The number 24 suggests that each of the mentioned organisms has 12 pairs of chromosomes, totaling to 24 individual chromosomes.

      15

    Correct Answer
    D. 4
    Explanation
    The diploid number of chromosomes refers to the total number of chromosomes found in a cell nucleus, where each chromosome is present in pairs. The answer to this question is 4 because Sus scrofa, also known as the domestic pig, has a diploid number of 38 chromosomes. Therefore, when counting the pairs, there are a total of 4 different diploid numbers of chromosomes in Sus scrofa.
