The result of cross two squashes with yellow seeds is an offspring of squash with green seeds -dominant caracter- heterozygous and yellow seeds squashes in a genotype proportion 1:2:1 and phenotype proportion 3:1
Explanation:
The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.
For the characteristic "seed color" the green color would be G and yellow represented as g.
However there is no exact time limit to decomposing, it could take up to 6 months to 15 years. To decompose it really relies on the temperature and the state of the environment.
Answer: An emission nebula is a cloud of ionized gas. The most common source for ionizations are high energy photons emitted from a nearby star. These can be among some of the most colorful objects in the sky. Reflection Nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars.
