Questions and Answers
  • 1. 

    Kromosom haploid merupakan kromosom yang…..

    • A.

      A. Jumlahnya setengah dari kromosom sel kelamin

    • B.

      B. Jumlahnya dua kali kromosom sel kelamin

    • C.

      C. Tidak berpasangan

    • D.

      D. Berpasang-pasangan

    Correct Answer
    A. A. Jumlahnya setengah dari kromosom sel kelamin
    Explanation
    Kromosom haploid merupakan kromosom yang jumlahnya setengah dari kromosom sel kelamin. Kromosom haploid hanya memiliki satu salinan dari setiap kromosom, sedangkan kromosom sel kelamin memiliki dua salinan dari setiap kromosom. Hal ini terjadi karena pada proses pembentukan sel kelamin, terjadi pemisahan kromosom sehingga setiap sel kelamin hanya memiliki setengah dari jumlah kromosom yang ada pada sel non-sel kelamin.

    Jika kromosom diploid suatu organisme   adalah 48,        jumlah kromosom haploidnya adalah…..

    • A.

      A. 48 pasang

    • B.

      B. 48 buah

    • C.

      C.24 pasang

    • D.

      D. 24 buah

    Correct Answer
    C. C.24 pasang
    Explanation
    The correct answer is c. 24 pasang. In a diploid organism, the total number of chromosomes is double the number of chromosomes in a haploid organism. Therefore, if the diploid organism has 48 chromosomes, the haploid organism would have half of that, which is 24 pairs of chromosomes.

    Jumlah kromosom diploid pada sel tubuh manusia       adalah…

    • A.

      A. 46 pasang

    • B.

      A. 46 buah

    • C.

      C.23 pasang

    • D.

      D. 23 buah

    Correct Answer
    C. C.23 pasang
    Explanation
    The correct answer is c. 23 pasang. This is because human body cells are diploid, meaning they contain two sets of chromosomes. Each set consists of 23 individual chromosomes, one from each parent, resulting in a total of 46 chromosomes. Therefore, the correct answer is 23 pairs of chromosomes.

    Sifat warna bunga merah dan bentuk biji  lonjong      merupakan contoh…

    • A.

      A. Genotipe

    • B.

      B. Gen

    • C.

      C. Kromosom

    • D.

      D. Fenotipe

    Correct Answer
    D. D. Fenotipe
    Explanation
    This question is asking for an example of a phenotype, which refers to the observable characteristics of an organism. In this case, the red color of the flower and the elongated shape of the seed are both visible traits, making them examples of phenotypes. Therefore, the correct answer is d. Fenotipe.

    Jika suatu individu bergenotipe AaBbCC, jumlah        gametnya adalah…

    • A.

      A. 1

    • B.

      B. 5

    • C.

      C. 6

    • D.

      C. 8

    Correct Answer
    B. B. 5
    Explanation
    An individual with the genotype AaBbCC will produce 5 different gametes. This can be determined by calculating the number of possible combinations of alleles for each gene. For the first gene, there are 2 possible alleles (A or a). For the second gene, there are also 2 possible alleles (B or b). And for the third gene, there is only 1 possible allele (C). By multiplying the number of possibilities for each gene, we get 2 x 2 x 1 = 4. However, since the individual is diploid, we need to account for the possibility of recombination during gamete formation, which can result in different combinations of alleles. Therefore, the individual will produce 5 different gametes.
