In a certain plant, yellow leaves are dominant (Y) and red leaves are recessive yA 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? (Hint. Draw a Punnett square to help you determine the answer) OA. 0 OB. 3 Oc. 1 OD. 2

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.

layer 3 is younger than layer 6.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
