So I don’t see answer choices here, but your answer is 50% of the offspring will be homozygous dominant with RR, and 100% of them will carry a homozygous dominant gene of Rr
If you take the two sets and put them into a punnett square, it would look like this (image attached):
When the two sets of alleles are crossed, you would end up with half of your pairs being fully dominant (RR), and the other half being dominant while containing a recessive gene (Rr). Since there’s only one recessive gene in these pairs, it gets overridden and the pair itself is dominant.
So your answer is 50% will be homozygous dominant with RR!
NACL is the correct answer
The size and position of their centres are the same for homologous Chromosomes
Answer:
Less water.
Explanation:
If the plant is "drought-resistant" then that should mean less water is required for the plant to perform photosynthesis.
The answer would be - It untwists the double helix and separates the two DNA strands. A helicase is an enzyme used to separate strands of a DNA double helix by breaking hydrogen bonds between annealed nucleotide bases.
