<span>Using a genetic cross, we can look at the following
A = brown a = White, B = Tall, b = small
With the capital letters being the dominant allele
A a
B AB aB
b Ab ab
The allele we are looking for is Ab which as 1/4 chance
To work out how many are in 2/6 also (1/3)
we do 1/4 x 1/4 x 1/4 = 1/64</span>
Answer:
The correct option is A. Matter is conserved during the burning of wood
Explanation:
One of the major theories of matter states that the amount of mass at the start of a reaction is equal to the amount of the mass at the end of the reaction.
As in Joan's study, he shows that the amount of carbon atoms remain 840 during each of the combustion reactions. The number of carbon atoms in wood at the start of the reaction was equal to the number of carbon atoms in carbon dioxide at the end of the reaction. Hence, Joan's model supports the theory that matter is conserved during the burning of the wood.
Answer: This told him that the allele for a green pod is dominant to the allele for yellow pods.
Explanation: Dominant traits will express themselves even if the allele for the other trait is there. If all of the offspring were green even though they carried the allele for a yellow pod, green must be dominant.
Answer:
The correct answer for the fill in the blank is - A sequence of bases on the DNA that codes for a trait.
Gene is described as a segment of DNA ( deoxyribonucleic acid) that codes for a particular protein, which in turn corresponds to a trait/ characteristic of the living organism.
Gene is first transcribed into mRNA ( messenger RNA) through a process called transcription. mRNA is then converted into protein through a process called translation.
The protein thus formed corresponds to a particular trait ( like eye color, hair color).
i hope this helps
