<em>2:4 homozygous recessive; 50% heterozygous.</em>
Explanation:
I will be using the letter B to represent dominant alleles and b to represent recessive alleles.
If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will <em>never </em>be both (BB) or (bb).
If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will <em>never </em>be (Bb). If the canary were homozygous dominant, it would be (BB).
I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...
<u>2:4</u> of the offspring will be potentially <u>homozygous recessive</u>.
<u>50%</u> of the offspring will be <u>heterozygous</u>.
The answer is; B
Mutations change the order of nucleotide and therefore affects codons that code for proteins. A different protein is thus produced from the wild type hence creating variations. Genetic shuffling in sexual reproduction, also called gene recombination occurs during meiosis and also when different organisms exchange genetic material such as in bacteria.
The expected e heterozygous phenotype would be orange.
Codominance is a type of non-Mendelian inheritance in which both alleles of one genotype are simultaneously expressed. So, in this example if allele A is responsible for red flower color and allele a for yellow flower color, Aa genotype (both alleles) will give both colors (red and yellow mixed together give orange).

Answer:
The correct answer is C
Explanation:
Codominance means that the result of two different genes will give separated characteristics of both. For example, if an animal has a gene of red skin and another gene of white skin, it will have red in some parts of the body and white skin in other parts. It can be confused with incomplete dominance, which combines the characteristics of the genes, in these case the skin would be pink, the combination of white and red. People who have one gene of it are carriers of the disease of course, because it can be passed to their sons.
