Amoeba Sisters: Monohybrid Crosses

The correct answer is "Homozygous" because it is the term used to describe a condition where an individual has two identical alleles for a specific gene. This means that both alleles inherited from the parents are the same, either both dominant or both recessive. In contrast, "Heterozygous" refers to the condition where an individual has two different alleles for a specific gene.

The question is asking for a preference between two options: "hair" and "no hair." The correct answer is "hair," indicating a preference for having hair.

The given options are different types of hair conditions. The correct answer is "hair" because it is a general term that refers to the presence of hair on the body. The other options, such as "no hair," "patchy hair," and "green hair," describe specific conditions or characteristics of hair.

Genevieve has the genotype "hh" because the answer states that she has the genotype "hh". The lowercase letters indicate that both alleles for the gene are recessive, meaning that she inherited the same recessive allele from both parents.

The genotype Hh would result in a 50% chance of the guineas being hairless. This is because the letter H represents the dominant allele for hairlessness, while the letter h represents the recessive allele for having hair. Since Hh is a heterozygous genotype, there is a 50% chance that the offspring will inherit the dominant allele and be hairless, and a 50% chance that they will inherit the recessive allele and have hair.

The correct answer is "Homozygous" because it means having two identical alleles for a particular gene. This means that both alleles inherited from the parents are the same.

The given options are different types or characteristics of hair. The answer "hair" indicates that the option represents the presence of hair.

The correct answer is "Hh" because it represents a heterozygous genotype, meaning that the individual carries two different alleles for the given trait. The uppercase "H" represents the dominant allele, while the lowercase "h" represents the recessive allele. This genotype indicates that the individual has inherited one dominant allele and one recessive allele for the trait in question.

The given statement suggests that if Fred has a genotype of GG, then all of the baby guineas would be hairless. However, this is not necessarily true. The genotype of an individual does not solely determine the phenotype or physical characteristics of their offspring. In this case, other factors such as the genotype of the other parent and the presence of any dominant or recessive alleles for hairlessness would also play a role in determining the phenotype of the baby guineas. Therefore, it is incorrect to claim that all of the baby guineas would be hairless if Fred's genotype was GG.

The correct answer is Hh, HH. This is because Fred's genotype could be either Hh or HH. The lowercase "h" represents the recessive allele for a particular trait, while the uppercase "H" represents the dominant allele. Since Fred's genotype could be either Hh or HH, it indicates that he has at least one dominant allele and may or may not have a recessive allele for the trait.

This statement is false because the physical appearance of a baby guinea pig does not necessarily indicate the number of alleles it has inherited from its mother. The inheritance of alleles is a random process, and a baby guinea pig can inherit a combination of alleles from both its mother and father. Therefore, the physical resemblance to the mother does not determine the number of alleles inherited.

The correct answer is "hh" because it is the only option that is written in lowercase letters. Both "HH" and "Hh" are written in uppercase or a combination of uppercase and lowercase letters, so they are not the correct choices.
