What are alleles 7th grade?

the different types or forms of a gene. one whose trait always show up in the organism when the allele is present. They are written in capital letters. the masked, or covered up allele that does not show up when the dominant allele is present.

What is a genotype example?

An example of a characteristic determined by a genotype is the petal color in a pea plant. The collection of all genetic possibilities for a single trait are called alleles; two alleles for petal color are purple and white. The genotype is one of three factors that determine phenotype.

Can As marry as?

They refer to the hemoglobin gene constituents on the red blood cells. AC is rare whereas AS and AC are abnormal. Compatible genotypes for marriage are: AS and AS should not marry, there is every chance of having a child with SS.

What are phenotypes 7th grade?

Phenotype: The physical appearance or what the gene makes an organism look like. Genotype: The genetic makeup of an organism. We use letters for the genotype.

• A gene encodes eye color.
• In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father.
• The brown allele is dominant (B), and the blue allele is recessive (b).

AS and AS should not marry, there is every chance of having a child with SS. AS and SS shouldn’t think of marrying. And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.

Can AA and SS get married?

AA marries an AA. That’s the best compatible. That way you save your future children the worry about genotype compatibility. And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.
