Review Quizzizz: Patterns of Inheritance - Chromosomes

What are the two different type of traits that humans can either 1. Gain from their parents or 2. Learn from others or their environments?

• Inherited

• Acquired/Learned

• Gained

• Spontaneous

What best describes a dominant allele?

• Symbolized by a capital letter, its trait will always appears in an organism if the allele is present in the genotype.

• Symbolized by a lowercase letter, its trait will always appears in an organism if the allele is present in the genotype.

• Symbolized by a number, its trait will always sometimes in an organism if the allele is present in the genotype.

• Symbolized by a capital letter, its trait will always be masked in an organism if the allele is present in the genotype.

A ______ allele is hidden whenever the dominant allele is present. *Usually this type of allele can only be expressed in a homozygous pairing.

A homozygous pairings has.....

• two identical alleles in the genotype

• two different alleles in the genotype

• two identical alleles in the phenotype

• two different alleles in the phenotype

Patterns of Inheritance: What are the 3 types that we talked about besides "Complete Domination"?

• Incomplete Domination

• Co-domination

• Multiple Alleles

• Multiple Dominations

• Co-Alleles

Incomplete domination takes place when one allele is partially dominant in the genotype. True or False

• True

• False

Co-dominance occurs when...

• both alleles for a gene are expressed equally

• both alleles mix for a weird combination, adding to genetic variability

• when 3 or more alleles control the expression of your trait

• when one allele completely masks the other in the genotype.

This Punnett Square is an example of which kind of Pattern of Inheritance.

*Notice how there are no recessive alleles. We have worked with problems like these before.

• Incomplete Domination

• Multiple Alleles

• Polygenic Inheritance

• Co-domination

Coming back to this Punnett Square; what is going to be the genotype and phenotype of the resulting offspring?
