Ok, so if your father or mother is O type, can you be an AB type?

The answer is no, since O type have to be homozygous recessive, meaning that A person with O type blood cannot have the gene for type A or type B.
for you to be an AB type, you must receive an A from mother and B from father, or the other way round. However, since father does not contain A or B gene ( if he does, he would not be an O type), this can never happen

What is the relationship between DNA, chromosomes, genes, alleles, dominant, recessive, and trait?
larisa86 [58]
Chromosomes are made of condensed coils of DNA. Genes are segments on a chromosome that carry the code for a specific trait. Alleles are contrasting forms of a gene. Dominant means that a particular trait will be visible. Recessive means that a trait will be hidden (unless it is paired with another recessive gene). A trait is how the gene is seen. For example, eye color is a trait.

Based on the information in the table, which of the following changes is least likely to produce a phenotypic
yaroslaw [1]

GAU to GAC​ is least likely to change phenotype of an organism.

<h3><u>Explanation</u>:</h3>

Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.

Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.

Both the GAU and  GAC​ codes for aspartic acid. So the phenotype won't be affected much by this mutation
