Using two heterozygous tall pea plants, so Tt is the genotype.

       T        t    <---- alleles from parent one

T      TT    Tt

t       Tt      tt

^alleles from parent two on the left

Results:  TT, Tt, Tt, and tt

Genotype ratio:  1/4 TT, 1/2 Tt, 1/4 tt

Phenotype ratio: T is dominant over t, so 3/4 tall and 1/4 short pea plants

The cell continually produces carbon dioxide as a by-product of cellular respiration. How does the cell keep the carbon dioxide
ser-zykov [4K]

Answer:

Breathing out the carbon dioxide

Explanation:

Blood is the medium through which carbon dioxide is transported to the lungs from where it is exhaled out.

The Carbon dioxide produced in cells after respiration diffuses into the blood  in exchange of oxygen delivered to the cells for further respiration. Blood while flowing through the lungs passes carbon dioxide to its alveoli which is then exhaled out and oxygen is inhaled from outside.

Hence, cell keep the carbon dioxide from building up in the cytoplasm and poisoning the cell by exhaling CO2.

The following the DNA sequence is a small part of the coding (nontemplate) strand from the open reading frame of β-hemoglobin ge
sdas [7]

The reading frame of the sequence would shift, causing a change in the amino acid sequence after that point.

Explanation:

DNA sequencing is important to apply to the human genome. It allows scientists to sequence genes and genomes. Since there is a limit to how many bases can be sequenced in one experiment, larger DNA molecules - as mentioned - have to be 'broken' into smaller fragments before they can be sequenced and re assembled. The normal allelic variant is 1600 base pairs (bp) long and contains three exons. The order of the genes in the beta-globin cluster is 5' - epsilon – gamma-G – gamma-A – delta – beta - 3'.
