I’m pretty sure the answer is C
Answer:
Tt - 1/2
tt - 1/2
Explanation:
<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>
Tt x tt
Offspring = Tt Tt tt tt (50% tall and 50% short)
If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):
Tt x tt
Offspring = Tt Tt tt tt
Genotype ratio = 2Tt:2tt
Hence,
Tt = 1/2
tt = 1/2
Enzymes are converted into products by the reactions they catalyze. One enzyme can catalyze many different reactions. ... They are molecules made of amino acids that speed up chemical reactions by lowering the activation energy.
