An organism with two different alleles for a trait is said to be:
- A.
Recessive
- B.
Hybrid
- C.
Dominant
- D.
Purebred
Correct Answer
B. HybridExplanation
An organism with two different alleles for a trait is said to be a hybrid. This is because a hybrid organism inherits two different alleles, or versions, of a gene for a particular trait from its parents. These different alleles can result in a combination of traits that is different from either parent. In contrast, a purebred organism has two identical alleles for a trait, while a dominant allele is one that is expressed over a recessive allele in determining the phenotype of an organism.Rate this question:

An allele whose trait is masked in the presence of a dominant allele is:
- A.
Dominant
- B.
Recessive
- C.
Purebred
- D.
Hybrid
Correct Answer
B. RecessiveExplanation
A recessive allele is the correct answer because it refers to an allele that is not expressed when a dominant allele is present. In genetics, dominant alleles will always be expressed in the phenotype, while recessive alleles will only be expressed if there are no dominant alleles present. This means that the trait associated with the recessive allele will only be visible when an individual has two copies of the recessive allele, as it is masked or overridden by the dominant allele when present.Rate this question:

- A.
Hybrid
- B.
Purebred
- C.
Phenotype
- D.
Genotype
Correct Answer
A. HybridExplanation
Heterozygous alleles are considered to be hybrid because they contain two different versions of a gene, one inherited from each parent. This means that the individual carrying heterozygous alleles has a combination of traits from both parents, resulting in a hybrid genotype.Rate this question:

- A.
Pascal triangle
- B.
Punnett Square
- C.
Purebred Cross
- D.
Hybrid Cross
Correct Answer
B. Punnett SquareExplanation
A Punnett Square is a chart used to show all the possible combinations of alleles that can result from a genetic cross. It is commonly used in genetics to predict the probability of certain traits being passed on to offspring. It is a visual representation that helps to determine the genotypes and phenotypes of the offspring based on the alleles present in the parents. The Punnett Square is a valuable tool in understanding and studying inheritance patterns in genetics.Rate this question:

What would be the results of a genetic cross between parents that have a BB and a Bb? (Making a chart will help)
- A.
BB, BB, Bb, Bb
- B.
BB, BB, BB, BB
- C.
BB, bb, BB, BB
Correct Answer
A. BB, BB, Bb, BbExplanation
The given correct answer shows the possible outcomes of a genetic cross between parents with genotypes BB and Bb. The first parent has two dominant alleles (BB) while the second parent has one dominant and one recessive allele (Bb). The possible combinations of alleles in the offspring are BB (dominant), BB (dominant), Bb (dominant), and Bb (dominant). This is because the dominant allele (B) masks the expression of the recessive allele (b). Therefore, the offspring will have either two dominant alleles (BB) or one dominant and one recessive allele (Bb).Rate this question:

If the results of a genetic cross were TT, TT, Tt, tt What would be the probability of getting a homozygous short? Note that T is dominant (tall) and t is recessive (short)
- A.
100%
- B.
75%
- C.
50%
- D.
25%
Correct Answer
D. 25%Explanation
In this genetic cross, the genotype TT represents a homozygous tall individual, while the genotype tt represents a homozygous short individual. Since there is only one tt genotype out of the four possible genotypes (TT, TT, Tt, tt), the probability of getting a homozygous short individual is 1 out of 4, which is equivalent to 25%.Rate this question:

If the results of a genetic cross were TT, TT, Tt, tt What would be the probability of getting a purebred tall? Note that T is dominant (tall) and t is recessive (short)
- A.
100%
- B.
75%
- C.
50%
- D.
25%
Correct Answer
C. 50%Explanation
In this genetic cross, the genotype of the parents must be Tt and Tt. The uppercase T represents the dominant allele for tallness, while the lowercase t represents the recessive allele for shortness. When two Tt individuals are crossed, there is a 25% chance of obtaining a purebred tall (TT), a 50% chance of obtaining a hybrid tall (Tt), and a 25% chance of obtaining a purebred short (tt). Therefore, the probability of getting a purebred tall is 25%, not 50%.Rate this question:

Which of the following is considered to be heterozygous?
- A.
TT
- B.
Tt
- C.
Tt
Correct Answer
B. TtExplanation
Heterozygous refers to having two different alleles for a particular gene. In this case, the alleles being referred to are T and t. The genotype TT represents a homozygous condition, where both alleles are the same (T). The genotype tt also represents a homozygous condition, but with both alleles being t. However, the genotype Tt represents a heterozygous condition, as it has one T allele and one t allele. Therefore, Tt is considered to be heterozygous.Rate this question:

It is NOT possible for two hybrid black rabbits (both Bb) to produce a white rabbit.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because in the given scenario, both rabbits are hybrid black (Bb), which means they carry one dominant black allele (B) and one recessive white allele (b). When these two rabbits mate, there is a possibility for them to produce offspring with the genotype bb, which represents a homozygous recessive white rabbit. Therefore, it is possible for two hybrid black rabbits to produce a white rabbit.Rate this question:

- A.
Inherited
- B.
Influenced by your environment
- C.
Both A & B
- D.
None of the above
Correct Answer
C. Both A & BExplanation
Both body weight and skin color are traits that can be influenced by a combination of genetics (inherited) and environmental factors. While genetics play a significant role in determining these traits, factors such as diet, exercise, and exposure to sunlight can also impact body weight and skin color. Therefore, the correct answer is "Both A & B."Rate this question:

An inheritance pattern in which the alleles are neither dominant nor recessive is called:
- A.
Codominance
- B.
Codependant
- C.
Cooperative
Correct Answer
A. CodominanceExplanation
Codominance is the correct answer because it refers to an inheritance pattern where both alleles of a gene are expressed equally in the phenotype. In this pattern, neither allele is dominant or recessive over the other, resulting in a unique phenotype that shows traits from both alleles. This is different from dominant-recessive inheritance, where one allele is dominant and masks the expression of the recessive allele. Therefore, codominance accurately describes the inheritance pattern where alleles are neither dominant nor recessive.Rate this question:
