1. In the late 1800s, Mendel predicted the existence of units of hereditary information or factors. What do we call these units of hereditary information today?

chromosomes or genes im not sure

2. Which term describes the form of a gene that produces a specific trait, such as eye color?

allele

3. Which term describes a type of trait that is usually expressed only when an organism has two identical alleles for the trait?

homozygous

8. Refer to the following information to answer Questions 8 and 9.

A certain species of grasshopper can have red stripes, yellow stripes, or red and yellow stripes. An RR grasshopper has red stripes, an YY grasshopper has yellow stripes, and an RY grasshopper has red and yellow stripes.

Which type of inheritance is this an example of?

codominance

9. A grasshopper with red stripes mates with a grasshopper with yellow stripes. What ratio would you expect to see in the phenotypes of their offspring?

all with yellow and red stripes

10. Which of the following best describes the relationship between a gene and an allele?

An allele is a variant of a gene.

11. Which of the following is the best physical description of a gene?

A gene consists of all of the DNA on a chromosome.

12. Suppose you cross a true-breeding blue flower with a true-breeding yellow flower. In the next generation, all of the flowers are blue. What does this outcome tell you about the allele for blue flowers?

The blue allele is dominant to the yellow allele.

If the moon were to suddenly disappear, which of the following would be a likely result? (Select all that apply)

solniwko [45]

Answer:

A. Fishing for sea life that lives on or near the shore would be more difficult.

C. The California Grunion fish would have a hard time laying eggs.

Explanation:

The moon is an important aspect of Earth's existence. It influences the change of "ocean tides" (high tide and low tide). If the moon were to suddenly disappear it will present a number of problems.

Firstly, the tides would all remain the same (small tides). They would also be smaller than the usual tide in the world today. Since the tide will be lower than usual, the marine organisms will not survive living on or near the shore anymore. This will make fishing for sea life in these areas more difficult.

The "California Grunion fish" normally lays its eggs along the coastal areas, which is out of the water. If the tide will be lower than usual, then they will have a hard time going to the coastlines for laying eggs.

So, this explains the answers.

The cladogram shown below describes the evolutionary relationship among several species, labeled A to F. The five dots represent

max2010maxim [7]

(You will find the cladogram in the attaches files)

Answer:

C. The genomes of species C and D are nearly identical because neither species has a derived character.

Explanation:

A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.

The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.
The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.

So the cladogram represents the relationship between groups according to a derived character.

The derivated character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.

A cladogram provides an image of how new species keep characters that were inherited from older species.

So, in the exposed example, the five dots represent derived characters, representing traits 1 to 5. Branches A to F, represent groups. (See the cladogram in the attached files). Group A inherited trait 1, group B probably still carries trait 1, but also trait 2. Groups C and D equally inherited trait 3. Group E inherited character 4, and finally, group F inherited character 5.

Groups C and D inherited trait 3 and probably also still have traits 1 and 2. So they are very similar to each other. At a certain point, they diverged, probably due to a new mutation that was not passed to the rest of the group.

C. The genomes of species C and D are nearly identical because neither species has a derived character. Correct.

Using your knowledge of Punnett squares and hybridization, what is the probability that a purebred monohybrid, dihybrid, three-f

Nimfa-mama [501]

Answer:

100%

Explanation:

No matter how many factors are in the cross, if an 2 purebred (homozygous individuals) are crossed, (one dominant, one recessive) the dominant phenotype will always be displayed.

Imagine a cross with between two individuals true breeding for 6 traits. One shows all dominant genotypes, one shows all recessive genotypes. The only gametes those individuals can pass on will always produce heterozygotes.

AABBCCDDEEFFGG x aabbccddeeffgg

The first individual can only give ABCDEFG alleles. The second individual can only give abcdefg alleles. Therefore, all offspring will be AaBbCcDdEeFfGg, and will therefore express the dominant trait.
