in certain plant yellow leaves dominant (y) and red leaves are recessive (y). a plant with genotype Yy and a plant with yy are c
rossed. if they four offspring, how many would you predict would have red leaves
2 answers:
Answer:
Two offspring would have red leaves, while two offspring would have yellow leaves.
Explanation:
As you can see in the Punnet square shown below, a cross between a plant with the "Yy" genotype and a plant with the "yy" genotype, would result in two plants with the American leaves and two plants with red leaves.
This is possible to observe because, the genotype responsible for the amerela leaves is the dominant genotype, represented by the letter "Y", any plant that receives this allele will have yellow leaves. However, red leaves are a recessive characteristic, represented by the "y" allele, only plants that have two "y" alleles, without the presence of any dominant allele, may have red leaves.

Answer:
A reaction that joins the nuclei of two atoms into one
Explanation:
Think of the words "nuclear fusion".
Nuclear = "relating to a nucleus"
Fusion = "joining"
So, nuclear fusion is the joining of two nuclei into one.
A and B are wrong, because chemical reactions involve electrons.
D is wrong, because the splitting of a nucleus is fission.
