snapdragon is heterozygous and has the genotype Cc. Suppose that a gardener crosses two yellow snapdragons, and one-third of the offspring are green and two-thirds of the offspring are yellow.
What type of allele could be responsible for the 2:1 offspring ratio seen when two yellow snapdragons are crossed?

B. polymorphic allele
C. recessive lethal allele
D. codominant allele

What type of allele could be responsible for the 2:1 offspring ratio seen when two yellow snapdragons are crossed?

dominant allele

As a result of two yellow snapdragons crossed, the dominat yellow allele gives the reason why the reult reflects in such a way that there is yellow dominates over green and leads to why yellow has two-third while green has one-third

What means RNA and it shape in the biology
MaRussiya [10]

The Answer is ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.

RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds.

I hope this helps you:)

Mutagens such as pollutants and uv light can cause mutations in dna
Darina [25.2K]

Answer:

<u><em>They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.</em></u>

Explanation:

Many mutations can lead to the formation of cancer. Cancer can be described as an abnormal type of cell division of the cells of the body. As cancer cells are the cells of the body dividing abnormally, the immune cells fail to fight them. These cells keep on dividing and also disturb the functioning of the neighbouring cells and tissues. They even take up most of the nutrients required by normal body cells hence, being very toxic for the normal cells.
