In a certain plant, yellow leaves are dominant (y) and red leaves are recessive (y). a plant with genotype yy and a plant with yy are crossed. if they have four offspring, how many would you predict would have red leaves?
a=4
b=1
c=2
d=3

The correct answer is - B) = 1

As per the information given in the question, yellow leaves (Y) is a dominant trait over red leaves (y) that is it will mask the expression of red leaves whenever the allele for yellow is present with the allele for red leaves.

The possible genotype for yellow leaves is YY and Yy whereas for red leaves is yy.

The genotype of parents is - Yy and Yy.

When they are crossed with each other, they will produce one plant with red leaves out of four offspring.

Refer punnett square.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
