Explanation:
all yellow
B.
all green
C.
three-fourths yellow and one-fourth green
D.
three-fourths green and one-fourth yellow
Answer:
The correct answer would be A. all yellow.
Let "Y" be the dominant allele and "y" be the recessive allele of the gene responsible for the color of the seeds.
Dominant allele "Y" codes for the yellow color of the seeds when present in homozygous as well as heterozygous condition whereas recessive allele "y" codes for the green color of the seeds only when present in homozygous condition.
Now, the genotype of a true-breeding plant with yellow seeds would be YY and that of a true-breeding plant with green seeds would be yy.
The gametes formed by yellow seed plant would be Y and gametes formed by green seed plant would be y.
The cross will result in the production of offspring each with genotype Yy.
Hence, all the offspring plants would produce yellow seeds as yellow is a dominant character.
carbonic acid freezing on rocks
b.
water and oxygen reacting
c.
water freezing and thawing
d.
rocks colliding with each other
Answer:
c. water freezing and thawing
Explanation:
Ice wedging is formed during the coldest days of the year, when we have winter, the water that reach the soil, starts to freeze. The water is a strange molecule, when is cold, and turns into a solid, we can observe that the volume increases, that is reason that the soil can split with an ice wedging.
