Sweet yellow tomatoes with a pear shape bring a high price per basket to growers. Pear shape, yellow color, and terminal flower

position are recessive traits produced by alleles, f, r, and t, respectively.
The dominant phenotypes for each trait – full shape, red color, and axial flower position – are the product of dominant alleles F, R, and T. A farmer has two pure-breeding tomato lines. One is full, yellow, terminal and the other is pear, red, axial. Design a breeding experiment (crosses) that will produce a line with tomato that is pure-breeding for pear shape, yellow color, and axial flower position.

Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.

The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.

With an individual of F1 crosses with another individual of F1, the Punnet Square will be:

FfRrTt x FfRrTt

1) Dividing each characteristics, for simplicity:

          F         f

F       FF       Ff

f        Ff        ff

          R       r

R       RR     Rr

r        Rr      rr

         T      t

T       TT   Tt

t        Tt     tt

Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.

What is the compliment base of thymine
serious [3.7K]
The answer is adenine.

The nitrogenous base pairings are always adenine with thymine and cytosine with guanine.

I remember this as

    · the two round letters (C and G) pair together
    · the two straight-edged letters (A and T) pair together

Hopefully that helps.

In order for transcription to happen, DNA must
nalin [4]

Answer: <u>Unwind </u>

Explanation: Transcription is a process where a DNA strand is used to make a copy of mRNA. A complementary mRNA strand is made from the DNA strand. This mRNA is then later used to make proteins. In this process the junk information, present in DNA in form of introns is also spliced.

DNA is a double stranded structure, which is present in helical structure and both the strands are twisted together. In order to make the mRNA copy with the help of the enzyme RNA polymerase, DNA must open up. Then only RNA polymerase will be able to access the nucleotides of DNA.
