Heredity
If a trait exhibits more than two possible phenotypes, which pattern of inheritance could be responsible?
Multiple alleles
Simple Mendelian inheritance
Epistasis
Pleiotropy
If genes exist in more than two allelic forms, this is called
x-linked
multiple alleles
incomplete dominance
codominance
A Punnett square that has sixteen squares is called a(n) _____.
Mendelian cross
Dihybrid cross
F1 generation
Monohybrid cross
In a certain species of plant, flower color is controlled by gene interactions where two genes affect pigment production; how might this result in a ratio that deviates from typical Mendelian ratios in an F2 generation?
No deviation from Mendelian ratios as gene interactions do not occur
A modified dihybrid ratio such as instead of
A classic Mendelian dihybrid ratio of
An incomplete dominance ratio such as
Which observation supports the concept that human skin color is an example of polygenic inheritance?
An albino individual inherits two recessive alleles at one gene locus controlling pigmentation
The presence of freckles as dominant over no freckles indicates single-gene inheritance
Crossing two medium-brown individuals sometimes results in very light- or very dark-skinned children
Skin color exhibits continuous variation across many different shades rather than discrete categories
How does a protein's tertiary structure influence its role in Mendelian genetic disorders?
Incorrect folding caused by a single amino acid change can result in nonfunctional proteins, leading to disorders like sickle cell disease.
A protein's primary sequence determines which genes will be turned off or on within a particular pathway influencing traits expression indiscriminately.
Proteins with quaternary structures bind DNA more tightly than those without, reducing mutation rates linked to genetic conditions.
Hydrophobic interactions among amino acids improve DNA polymerase fidelity during replication, preventing inherited diseases.
Which genetic mechanism can explain why humans have such genetic variation despite having a few number of genes?
Polgenic inheritance allows multiple genes to contribute collectively to various traits.
Pleiotropy indicates that single genes may produce multiple phenotypic effects, which reduce variation.
X-linked inheritance causes most genetic traits to be associated with the X chromosome, thus restricting diversity.
Mendelian ratios are always observed, suggesting limited genetic variation in humans.
