Which of the following correctly describes the law of segregation? A) It states that the segregation of the dominant trait in the phenotype happens in the hybrid offspring. B) It states that all the genetic factors are present in the DNA. C)It states that allele pairs segregate during gametogenesis and reunite randomly during the fertilization process. D) It states that the hereditary factors segregate independently of one another during gametogenesis. - Correct Answer It states that allele pairs segregate during gametogenesis and reunite randomly during the fertilization process is the correct answer. The law of segregation states that each pair of alleles segregate randomly during gametogenesis (gamete formation). This means that each gamete (sex cell) receives one copy of a gene (an allele). They later reunite or combine randomly during fertilization. This way, the offspring acquires one allele from each of the parents. The law of ________ states that the offspring will always display the dominant trait in the phenotype by suppressing the recessive trait. A) independent assortment b) dominance C) segregation - Correct Answer dominance The law of ______assortment states that the traits inherited by the offspring are independent of each other. Two or more traits do not influence one another. A) independent assortment b) dominance C) segregation - Correct Answer independent assortment ionic bond - Correct Answer Formed when one or more electrons are transferred from one atom to another examples of ionic bonds - Correct Answer NaCl hydrogen bond - Correct Answer weak attraction between a hydrogen atom and another atom, a bond between a partial positive and a partial negative examples of hydrogen bond - Correct Answer DNA and proteins polar bond - Correct Answer a covalent bond in which electrons are shared unequally
