which type of cell division (mitosis v meiosis) increases the likelihood of variation with a species? explain how it happens?

In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cro

Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)

Understanding wobble rules select all the anticodons that could bind to the codon for serine. choose all that apply. check all t

Kipish [7]

A codon is a tree letter nucleotide sequence in the mRNA. The tRNA anticodon attached to the corresponding amino acid recognizes the mRNA codon. A single amino acid can have more than one codon.

The serine codon can be one of the following:

TCT, TCC, TCA, TCG, AGT, AGC
