HELP !Mendel made crosses between pure-breeding tall pea plants with purple
flowers and pure-breeding short pea plants with white flowers. The alleles for
a tall height and purple flowers were dominant. This cross is written as
A. TtPpx TtPp
в. TTppx ttPP
с. Ttppx TtPP
D. TTPPx ttpp

Answers

Answer 1
Answer:

Answer:

The correct answer is - ttPP × TTpp

Explanation:
Answer 2
Answer:

Answer:

D

Explanation:

He bred two true-breeding strains initially. That means the alleles were homozygous for each gene.

Let's use Tt to represent the height allele: T means tall, t means short; the dominant allele gets the capital letter.

Let's use Pp to represent the flower color allele: P means purple, p means white.

A pure-breeding tall, purple plant would be TTPP.

A pure-breeding short, white plant would be ttpp.

So the cross is D. TTPP x ttpp.

I think C

Answers

Alleles are two different forms of single gene that are located in specific position on a specific chromosome. It can be classified into two allele pairs: homozygous and heterozygous. In homozygous, both alleles are the same whether they are both dominant or recessive; while in heterozygous, one allele is dominant and the other is recessive.

Bacterial blank are sites of metabolite storage?

Answers

Answer:

Bacterial inclusions are sites of metabolite storage.

Explanation:

Bacteria is a prokaryote which means that it lacks membrane bound structures.

Bacterial inclusions can be described as structures present in the bacterial cell which function as metabolic reserves or metabolic organelles. They are also called as elementary bodies. The bacterial inclusions are usually cytoplasmic aggregates of the bacterial cytoplasm. These inclusions are known for forming compartments in the bacterial cell. However, various inclusions can also be seen in the eukaryotic cells.
