Answer: The Miller - Urey experiment is an experiment that was conducted by Stanley Miller and Harold Urey last 1950's. The hypothesis that they had tested and demonstrated was that several organic compounds could be formed by simulating the conditions of Earth's atmosphere.The Miller-Urey experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components. Some scientists support the RNA world hypothesis, which suggests that the first life was self-replicating RNA.

Answer:

12 : 3 : 1

Explanation:

According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and 1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.

<em>Dihybrid cross for heterozygous summer squash:</em>

WG Wg wG wg

WG WWGG WWGg WwGG WwGg

Wg WWGg WWgg WwGg Wwgg

wG WwGG WwGg wwGG wwGg

wg WwGg Wwgg wwGg wwgg

Genotypes:

W-G- and W- gg = white = 12

ww G- = yellow = 3

ww gg = green = 1
