HELP ASAP<br> Punnett Squares

Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt

The phenotype ratio is that all offsprings will be tall.

The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.

Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.

Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.

The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.

The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.

Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.

The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.

See the attached punnet squares for details of the cross.

What stood atop a covered chemical waste dump at Love Canal, New York?
Dafna1 [17]
<h2><u>Answer:</u></h2>

Love Canal. In 1978, Love Canal situated close Niagara Falls in upstate New York, was a pleasant small average workers enclave with many houses and a school. It coincidentally sat on 21,000 tons of lethal modern waste that had been covered underground during the 1940s and '50s by a neighborhood company.

The waterway families didn't realize that they were being presented to harmful synthetic substances, nor were they mindful that concoction squanders were being dumped in our streams, soil, and air. Love Canal stirred a network to the disagreeableness and appalling acknowledgment of how lethal squanders influence our lives, and pulverize our condition.
