In pea plants, flowers are either white or purple; the purple color is produced by pigments called anthocyanins. The production

of anthocyanins is a two-step process: the first is controlled by the C gene and the second by the P gene. Both genes must produce functional proteins for anthocyanin to be expressed. For each gene, the dominant (C and P) alleles produce functional proteins. You cross two pea plants, each with the genotype CcPp. What proportion of their offspring will have white flowers?

Answer:

7/16

Explanation:

<em>The proportion of the offspring from the cross that will have white flowers is 7/16.</em>

The presence of anthocyanin which determines purple coloration is conditioned by the C_ and P_ alleles. It means that the absence of one or both of C and P will result in white flowers.

Two plants, each with CcPp are crossed:

CcPp   x   CcPp

Offpring

1 CCPP - purple

2 CCPp - purple

2 CcPP - purple

4 CcPp - purple

2 Ccpp - white

1 CCpp - white

1 ccPP -  white

2 ccPp - white

1 ccpp -  white

Proportion of offspring with white flowers = 7/16

Proportion of offspring with purple flower = 9/16

<em>See the attached image for the Punnet's square analysis of the cross.</em>

Which best explains the evolution of gymnosperm plants?
grin007 [14]
The answer to this question about the evolution of the gymnosperm plants would be C. They evolved after the seedless vascular plants.

Gymnosperms, or sometimes termed as seed plants, are classified as vascular plants and has been thriving for centuries on earth through producing seeds. They are multicotyledonous and are the opposite of flowering plants. Conifers would be the most abundant group of gymnosperms while the cycads come in second. Gingko would place last with just having one species under its name.

astraxan [27]

The Griffith's experiment, the Avery-MacLeod-McCarty experiment, and the  Hershey–Chase experiments were the set of experiments that established DNA as the key hereditary molecule. The Avery-MacLeod-McCarty experiment was an extension to the Griffith's experiment. The heat killed virulent S strain cells of the Griffith's experiment were lysed to form a supernatant containing a mix of RNA, DNA, proteins and lipids from the cell. The supernatent was equally divided into 3 parts after the removal of the lipids. The 3 parts were respectively treated with an RNAase to degrade the RNA, DNAase to degrade the DNA and proteinase to degrade the proteins. The treated supernatant was then added into the culture containing the non-virulent R cells. In case of the supernatant treated with the DNAse, no transformation of R cells into S cells occurred. The transformation of R cells to S cells occurred in the proteinase and the RNAse cases. This indicated that DNA was the hereditary molecule and not protein or RNA.
