10th Class Biology – Short Questions & Answers

  • Explain the human female reproductive system.

    Explain the human female reproductive system.

    The female reproductive system includes the ovaries, fallopian tubes, uterus, cervix, and vagina. It is responsible for the production of eggs, fertilization, and gestation of the fetus.

  • Describe the process of human fertilization and development.

    Describe the process of human fertilization and development.

    Fertilization occurs when sperm meets the egg in the fallopian tube, forming a zygote. The zygote divides to form a blastocyst, which implants in the uterus. The embryo develops into a fetus, undergoing growth and differentiation, until birth.

  • Define heredity.

    Define heredity.

    Heredity is the transmission of genetic characteristics from parents to offspring, passing down traits through genes.

  • What is a gene?

    What is a gene?

    A gene is a segment of DNA that contains instructions for producing proteins, determining inherited traits.

  • Explain the term ‘allele’.

    Explain the term ‘allele’.

    An allele is a variant form of a gene that can exist in different forms (dominant or recessive) and determines specific traits.

  • What is a dominant trait?

    What is a dominant trait?

    A dominant trait is one that is expressed in the phenotype of an organism, even if only one copy of the allele is present.

  • Define recessive trait.

    Define recessive trait.

    A recessive trait is expressed in the phenotype only when two copies of the recessive allele are inherited, one from each parent.

  • What is a genotype?

    What is a genotype?

    Genotype refers to the genetic makeup of an organism, representing the specific alleles inherited for a particular gene or set of genes.

  • Define phenotype.

    Define phenotype.

    Phenotype refers to the observable physical characteristics of an organism, influenced by its genotype and environmental factors.

  • What is Mendel’s Law of Segregation?

    What is Mendel’s Law of Segregation?

    Mendel’s Law of Segregation states that each organism carries two alleles for each trait, and these alleles separate during gamete formation, with each gamete receiving one allele.
