A farmer crossed a yellow maize plant (Yy) with another yellow maize plant (YY). He planted 200 seeds from this cross. How many of the plants would be yellow?

Answers

Answer 1

Answer: 200 seeds will be yellow.

Explanation: In this crossing, one parent will produce half of its gametes carrying allele Y and the other half carrying allele y. The other parent will have gametes with allele Y. After fecundation, the offspring could phenotype YY or phenotype Yy.

In genetics, Y is related to the dominant allele and y to the recessive one. In this case, having the Y dominant allele determine the color yellow. Therefore, as all of the offspring has the dominant allele Y for yellow, all of the seeds will be yellow, i.e., 200 seeds will be yellow.

In which two ways will a dog contribute to the carbon cycle

Answers

Dogs tend to eat meat, after all, and meat production is a major contributor of greenhouse gas emissions. By one estimate, it's even the largest. And dogs tend to eat highly processed meat, so their carbon pawprint grows as their food is manufactured, and again as it is transported.
