Answer:
9/16= tall and yellow offspring
Explanation:
Two dihybrid pea plants for color and height are crossed to obtain the progeny. The genotype of both the parents is "TtYy".
Each of the dihybrid parent will form four types of gametes in 1:1:1:1 ratio= TY, Ty, tY and ty. A random fusion of gametes from both the parents would give a progeny in following phenotype ratio=
9 tall and yellow: 3 tall and green: 3 dwarf and yellow: 1 dwarf and green
<span>The transmission of information from DNA to RNA is a critical process. We compared RNA sequences from human B cells of 27 individuals to the corresponding DNA sequences from the same individuals and uncovered more than 10,000 exonic sites where the RNA sequences do not match that of the DNA. All 12 possible categories of discordances were observed. </span>
