In peas, yellow seed color (Y) is dominant to green seed color (y). A homozygous green pea plant is crossed with a heterozygous yellow pea plant. What is the predicted phenotypic ratio of the offspring? A.50 percent yellow, 50 percent green B.50 percent Yy, 50 percent yy C.100 percent yellow, 0 percent green D.100 percent Yy, 0 percent yy

Answers

Steps:
1. Do a pun-net square
y y
Y
y
2. Your offspring would be Yy, Yy, yy, yy
3. Your answer would be B

A homozygous green (yy) pea plant is crossed with a heterozygous yellow (Yy) pea plant. The phenotypic ratio of the offspring is 50 percent Yy and 50 percent yy.

Further Explanation:

Genotypes help in the genetic makeup of any individual. Phenotype describes as a physical characteristic of an individual. The genotype is responsible for the phenotypes of any individual. If two copies of the same alleles present in an organism, its genotype is called homozygous. If two copies of different alleles present in an organism, its genotype is called heterozygous.

When a homozygous dominant individual is crossed with the homozygous recessive individual the resultant offspring has the genotype which is heterozygous and phenotype which is dominant. All possible genotypes of the parent as well as offspring are graphically represented in a Punnett square.

In the given punnet square below, the parent homozygous green plant having a genotype yy is crossed with the parent heterozygous yellow plant having a genotype of Yy. The resultant offspring of filial generation tends to be 50 percent of Yy which means heterozygous and 50 percent yy which means homozygous.

Gerta finds a sedimentary rock with large clasts cemented together. Each clast is larger than 2 mm. Gerta has found _____.sandstone
an evaporite
limestone
a conglomerate

Answers

Gerta has found a conglomerate.

Conglomerate is a clastic sedimentary rock that contains large (greater than two millimeters in diameter) rounded particles. The space between the pebbles is generally filled with smaller particles and/or a chemical cement that binds the rock together.

The answer is the final choice; a conglomerate.

Most current theories about the eventual fate of the universe draw their conclusions based on the universe’sa. Density
b. Energy
c. Mass
d. Volume

Answers

The answer is (b.) Energy

Among the choices, energy is the closest to the answer. There are many theories about the universe and most of them draw their conclusions based on the energy in the universe. An Example is the theory of Big Freeze. It states that the universe has a fixed amount of energy and then when it runs out, the universe will slow down.

Correct answer is C.) mass. Just took the quiz
