3. A TT (tall) plant is crossed with a tt (short plant). What percentage of the offspring will be tall
Evgesh-ka [11]

A heterozygous species contain one dominant and one recessive allele. A cross between a purebred tall and short plant will result in 100% tall offspring. Thus, option d is correct.

<h3>What is a genetic cross?</h3>

A genetic cross is a representation of the gametes produced by the two parent species that will undergo the process of fertilization to produce offspring. The crosses can include the heterozygous and purebred species.

The TT allele is a purebred allele that codes for tallness, whereas the tt allele is a purebred recessive allele that codes for shortness. The cross between TT and tt is attached to the image below.

From the cross, it can be said that all the offspring produced are heterozygous tall as there are no offspring with purebred dominant and recessive alleles.

Therefore, option D. 100% of offspring are tall.

According to the instruction manual analogy, how many new volumes would each new cell contain whenever a cell splits? Write your
lorasvet [3.4K]

Answer:

Same volume as the cell it is divided from.

Explanation:

The particular volume will be diverse for different sorts of cells. The best answer would be that the new cell will essentially have a similar volume as the one that it formed or divided from. This is valid for most eukaryotic cells except if different variables like mutations or epigenetics condition.

Increasing volume of the cell and now likewise associated with cell division would be during the two phases G1 and G2 in the cell cycle. This is the development period of the cell preparing for division. No matter what are the condition other than mention above if mitosis or division occurs, the cells will ordinarily end with a similar volume as when it began.
