Questão 5
Questão
What is homozygous dominant?
Responda
Where there is two dominant alleles
Where there is two recessive alleles
Questão 6
Questão
What is homozygous recessive?
Responda
Where there are two dominant alleles
Where there is a dominant and recessive allele
Where there is two recessive alleles
Questão 7
Questão
What is a codominant allele?
Responda
Where there is a dominant and recessive allele
Where two alleles both contribute to the phenotype so both features are represented
Where the recessive alleles are only present in the phenotype

Representing Genetic Crosses
1) Choose a single letter to represent each characteristic. This makes it [blank_start]easier as it is in short hand[blank_end].
2) Choose the first letter of one of the contrasting features. This makes it [blank_start]easier to identify which characteristic[blank_end] is being used.
3) Choose a letter which the higher and lower case differs in size and shape. This [blank_start]makes it hard to confuse the letters[blank_end].
4) Higher cases represent the [blank_start]dominant feature[blank_end], lower case letters represent the [blank_start]recessive feature[blank_end].
5) Represent the parents with appropriate pairs of letters and state their [blank_start]phenotypes[blank_end].
6) State the gametes produced and circle them. This [blank_start]reinforces that they are separate[blank_end].
7) Use a [blank_start]Punnett square[blank_end] to show the results of random crossing and label male and female. This makes it [blank_start]less likely to make an error.[blank_end]
8) State the phenotypes of each different genotype and always put the higher case first. This [blank_start]reduces error when reading[blank_end].
