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 (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?
(a)
Name the two structures that make up a chromosome.
Centromere
Chromatids
Chromazoids
Chromatin
How many chromosomes does the adult human body cell have?
46 chromosomes
48 chromosomes
50 chromosomes
44 chromosomes
How many chromosomes do human sperm and egg cells have?
23 chromosomes
24 chromosomes
25 chromosomes
22 chromosomes
DNA is stored in the form of chromosomes. True or False?
True
False
This Punnett Square is an example of what kind Pattern of Inheritance.
*Notice the use of the letter C in the alleles. That should tell you something.
Co-dominance
Incomplete Domination
Complete Domination
Multiple Alleles
Free Earlobes or Attached Earlobes; Acquired or Inherited Trait
