Answer:

B. Thermal energy will move from the plate to the fruit pop.

Explanation:

If you leave a frozen fruit pop that has a lower degree than the object you place it on, the object with the higher temperature will transfer heat to the colder object, which leads the cold object to melt.

A maize plant with genotype Aa Bb produces the following gametes 100 Ab 45 AB 106 aB 50 ab This tells us that the two genes are
bogdanovich [222]

Answer:

True

Explanation:

The linkage relation of two genes can be determined on the basis of calculating recombination frequency.

If the recombination frequency value is greater than 50% then the genes are not linked and if the value is less than 50% then the genes are linked.

In the given question, the  crossover gametes formed will be Ab = 100

and aB= 106.

Therefore,

\dfrac{recombinant\ progenies}{ Total\ progeny}\times 100\\\\\dfrac{100 +106}{100+106+45+50}\times 100\\\\=\dfrac{206}{301}\times 100\\\\= 68.43\%

Since the recombinant frequency value is larger than 50% therefore the genes do not show linkage.

Thus, True is the correct answer.
