1. Which of the following statements best describes heredity in organisms that reproduce sexually?
A. All four offspring received all of their genetic information only from Parent 1 and
are therefore identical to that parent
B. All four offspring received all of their genetic information only from Parent 2 and
are therefore identical to that parent.
C. All four offspring are genetically unique and did not receive any of their genetic
information from either parent.
D. Each of the offspring is genetically unique and received some of its genetic
information from each parent, so each has some traits in common with each
parent.

Explanation:

While reproducing sexually, The zygote receives half of the gametes of male organism while half of the gametes of female organism. This constitutes to the total number i.e. 46 chromosomes.

While the zygote receive half from male and half from female, This means that the offspring produced by the zygote will have both the characteristics in common of the male as well as female. Remember that, Chromosomes contain gene which are particularly responsible for characteristics.

So, Each of the offspring is genetically unique and received some of its genetic  information from each parent, so each has some traits in common with each

parent.

Hope this helped!

the binding of the substrate is dictated by the shape of each molecule. side chains on the enzyme interact with the substrate in a specific way, resulting in the making and breaking of bonds.

the answer would be knowledge about cars!
