- In every beehive, there is one queen bee who lays all the eggs. If an egg is not fertilised, it hatches into a male bee, called drone. If an egg is fertilised, it hatches into a lady worker bee, which does not lay any eggs.a. Consider a drone. How many parents, grandparents, great grandparents, great-great grandparents, great-great-great grandparents, great-great-greatgreat grandparents does it have?b. Write a mathematical sentence which can be used to represent the number grandparents a drone has during a particular generation.Which of the following is the definition of the term named Homozygous? a.Refers to genes that have identical alleles b.Genetic constitution of an organism c.Alternative form of a gene d.Trait expressed in the F1 generation e.Fundamental physical and functional unit of heredity f.Physical expression of traits of an organismWhich of the following does not describe a gene?

What gametes does the mother produce? a. T b. t c. T and t d. Tt e. TT JIn humans, unattached earlobes (E) are dominant to attached earlobes (e). If a child is born with unattached earlobes, and a mother with attached earlobes, and a dad with unattached earlobes, what is genotype of the dad? O a. EE or Ee O b. ee O c. Ee O d. Ee or ee O e. EEIn a natural population it was noticed that some natural variants with different forms, behaviors or physical traits are better at getting through life and reproducing compared to other others. Look at the diagram below, decide which choice best explains why the natural occurring trait is passed on. 1 2 RRORS O Brown fur color in mice blends in with the environment better so the brown mice will survive and pass on their fur color traits O White fur color in mice blends in with the environment better so the white mice will survive and pass on their fur color traits O Both brown and white fur color in mice blend in with the environment well so both types of mice will survive and pass on their fur color traits
