True or false?
Codominance and complete dominance establish the same pattern of inheritance.
Two examples that show deviation or extensions of simple Mendelian genetics.
MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The Mendelian pattern of inheritance is a general term that refers to any pattern of inheritance in which traits do not segregate in accordance with Mendel’s lawsII. As an example, a characteristic may be controlled by one gene with two alleles, but the two alleles have a same relationship like the simple dominant-recessive relationship
a. The first statement (I) is correct and the second statement (II) is wrong
b. The first statement (I) is wrong and the second statement (II) is correct
c. Both statements are correct
d. Both statements are wrong
MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle.II. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce…

- MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The law of segregation states that the two alleles for a heritable character separate during gamete formation and end up in a same gamete.II.

Mary is a carrier of the allele for sickle cell anemia but has no sign of any neurodegenerative disorder in her family. She married Paul whose father died of Huntington’s disease.
