kati45 [8]

Answer:

The test cross is shown below

      T         T

t      Tt         Tt

t       Tt         Tt

The alleles shown in the vertical side (tt) are recessive and come from the male parent. The alleles TT are dominant and come from the female parent.

For the variety of offsprings to be 100% tall, the recessive parent had to be crossed with a homozygous dominant parent.  If the female was heterozygous with which the cross was done,then there would be small tomato plants in the offspring generation.

Based on the information in the graph, which blood type is most likely to be in shortest supply during an emergency?
Maksim231197 [3]
While there is no graph provided and I cannot find the graph online, I will base my answer through theory. 

In theory, the most common blood type is O+, followed by A+, then B+, then AB+. Rh negative blood is deemed to be rare. While the most common blood type is O+, the same blood type is also called the "universal donor" as a type O+ blood has no antigens attached in red blood cells therefore the probability of adverse reactions (i.e. hemolytic reactions) when transfused to other blood types are close to nil. In an emergency situation, wherein there is not enough time to do proper crossmatching, blood type O+ can be used therefore supplies of blood type O+ are easily depleted.
