Answer:
1. law of Independent Assortment; metaphase I; independent of.
2. law of Segregation; meiosis I; in separate gametes.
Explanation:
Between 1856 and 1863, Gregor Mendel developed a series of mating experiments using pea plants, which enabled the discovery of some basic principles of inheritance. These principles/laws are stated as:
1) Law of segregation: this principle states that the inheritance pattern of phenotypic traits is characterized by the presence of a gene pair and each gamete carries only one allele for each gene pair so offspring inherit one gene variant (allele) from each parent
2) Law of independent assortment: this principle states that the genes responsible for the inheritance pattern of different traits are independently sorted from one another and thereby different traits are independent one from another.
3) Law of dominance: this principle states that the dominant allele will always be expressed in heterozygous individuals (this law is only applicable in cases of complete dominance).

If a protein will end up with 30 amino acids, how many codons, not including the STOP codon, were on the mRNA
transcript that produced it?
Answer:
30 codons
Explanation:
Translation is the second process of gene expression, which involves the synthesis of amino acid sequence from mRNA. This process occurs in the ribosome where the mRNA is read in a group of three nucleotide bases called CODON. Each codon specifies a particular amino acid.
Since one codon specifies or translates into one amino acid, a protein with 30 amino acids will contain 30 codons (exclusive of STOP CODONS) on the mRNA transcript.
