TEAS Exam 2023: Science with Correct Answers

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. - 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 - 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 - Answer-independent assortment ionic bond - Answer-Formed when one or more electrons are transferred from one atom to another examples of ionic bonds - Answer-NaCl hydrogen bond - Answer-weak attraction between a hydrogen atom and another atom, a bond between a partial positive and a partial negative examples of hydrogen bond - Answer-DNA and proteins polar bond - Answer-a covalent bond in which electrons are shared unequally example of polar bond - Answer-H2O
