13. Mendelian Genetics

Genotype vs. Phenotype

One trait that is shared by the Lophotrochozoa and Ecdysozoa is                .

Genotype vs Phenotype | Understanding Alleles

An allele that exerts its effects whenever it is present is:

Genotype & Phenotype

GCSE Biology - DNA Part 2 - Alleles / Dominant / Heterozygous / Phenotypes and more!  #64

A team of 102 scientists spent a year surveying a small area of the San Lorenzo rain forest in Panama to count the number of species of arthropods living there. After collecting 129,494 specimens—using nets, traps, shovels, tree-climbing harnesses, helium balloons, and other creative gear—it took the team eight years to sort and identify the arthropods.

Which of the following nested groups best describes the taxonomic context for the San Lorenzo project?
a. Animalia > Bilateria > Arthropoda > Ecdysozoa
b. Protostomia > Lophotrochozoa > Ecdysozoa7 Arthropoda
c. Arthropoda > Protostomia > Ecdysozoa > Bilateria
d. Bilateria > Protostomia > Ecdysozoa > Arthropoda

Dominant vs. Recessive Alleles

The yellow allele masks the effects of the green allele in an individual heterozygous for pea color.

Both individuals who are heterozygous and homozygous dominant for pea color will have yellow peas.

Only individuals who are homozygous recessive for pea color will have green peas.

The green pea color allele can be found in some individuals but not expressed.

Mendel’s pea plants can have yellow peas or green peas. Mendel found the yellow pea color allele to be dominant over the green pea color allele. What does this mean?

If the two alleles for a particular gene are identical the gene pair is:

What is the relationship between genotype and phenotype?

Genotype vs Phenotype

Difference between Genotype and Phenotype | Genetics

 No. The genotype is homozygous recessive for colored squash. 

 No. This is a system of dominant/recessive alleles. There is no incomplete dominance or codominance. 

 No. The genotype is heterozygous for yellow, so the dominant color will be expressed. 

What is the definition of epistasis?

Color in squash is controlled by epistatic interactions in which color is recessive to no color. At the first locus, white squash (W) is dominant to colored squash (w). At the second locus, yellow (Y) is dominant to green (y). What is the phenotype of a squash with the genotype wwYy?

 No. This genotype expresses a phenotype that expresses only one dominant trait. 

 No. This genotype expresses a phenotype that is recessive for all three characters. 

 No. This genotype expresses a phenotype that is dominant for all three characters. 

 None of the listed responses is correct. 

 No. One of the listed responses is correct. 

Consider the meaning of the term completely dominant.

In a certain plant, the alleles A, B, and C are completely dominant to the alleles a, b, and c. A plant with the genotype AABbcc will have the same phenotype as a plant with the genotype __________.
