There is only 1 unique phenotype observed in the offspring. As all offspring produced would have the genotype of Aa. In which the characteristic for the dominant allele will be seen in all offspring. As all offspring are Aa. There is only 1 unique phenotype. Here based on the characteristic or phenotype expression of the dominant allele.

Which statements describe the inheritance of traits? Select three options.
liraira [26]

Answer:

<u><em>The correct options are:</em></u>

<u><em>All traits are inherited.</em></u>

<u><em>Offspring inherit one allele for a gene from each parent.</em></u>

<u><em>An offspring with two identical alleles for a trait is homozygous.</em></u>

Explanation:

  • In the biological world, a trait can be described as a genetic characteristic which makes up an organism. Every organism has a particular set of traits.

  • Traits are inherited from parents, however they can be influenced by the environment.

  • The alleles of a gene make up the genotype and the influencing phenotype. An organism acquires one allele for the gene pair from each parent.

  • When both the alleles of a gene pair are similar, the organism is said to be homozygous for the trait. If both the alleles of a gene pair are different, the organism is said to be heterozygous for the trait.

Kitty [74]

Answer:

For the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).

Explanation:

Transfer RNA or tRNA is responsible for driving the right amino acid into protein synthesis, once the mRNA codon has been translated by the ribosome. It is for that reason that each mRNA codon must have a complementary tRNA anticodon.

The RNA pairing rules is that each nitrogenous base has a complementary base, so:  

- Adenine is complementary with uracil A=U

- Cytosine is complementary with Guanine C=G

In this case, it can be seen that:

  • <em>For the anti-codon:  CCA</em>
  • <em>Codon:                      GGU</em>
  • <em>Aminoacid:               Gly</em>
