What phenotypic ratio would you expect as a result of a test cross between a dihybrid organism and one that is homozygous recess
Artyom0805 [142]

Answer:

¼ or 25% will be dihybrid organisms, ¼ will be heterozygous at first locus and recessive homozygous at other locus , ¼ of them will be recessive homozygous at first locus and heterozygous at other locus, and ¼ of them will be homozygous recessive for alleles at two independent loci.

Explanation:

A dihybrid organism is one that is heterozygous at two different genetic loci. So if we name one gene with D and other gene with R, dihybrid organism will have genotype DdRr.

If we cross that organism with the one that is homozygous recessive for alleles at two independent loci ddrr:

P: DdRr  x ddrr

Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well as some
xz_007 [3.2K]
The best answer in this case is C, "the researchers applied creativity to solve a problem in running an experiment".

Distributing the computing load across the global community by sharing processing power is a creative response to tackle the challenge in simulating protein folding for the experiment. This does not change or reduce the scientific merits of the experiment, so we can discount the first two answers (a & b). Answer d talks about well established scientific techniques, although the question wasn't really centered around the specific techniques, so it's not as relevant an answer as C.
