In a dihybrid cross, how many phenotypic ratios are possible? (9:3:3:1)

In a dihybrid cross, only one phenotypic ratio is possible which is the classic 9:3:3:1 ratio. This ratio represents the distribution of phenotypes resulting from the combination of two different gene pairs segregating independently in a cross.

What is the term used to describe the inheritance pattern where both alleles in a heterozygous individual are fully expressed? (Dominance)

The term used to describe the inheritance pattern where both alleles in a heterozygous individual are fully expressed is called codominance.

How is a genotype different from a phenotype? (Genotype refers to the genetic makeup of an organism, while phenotype refers to the physical appearance or traits exhibited)

A genotype refers to the genetic makeup of an organism, including the alleles and genetic information carried by an individual. On the other hand, a phenotype refers to the physical appearance or traits exhibited by an organism as a result of its genotype interacting with environmental factors. In simpler terms, genotype is the genetic blueprint of an organism, while phenotype is the actual physical expression of those genes.

What is the term used to describe a genetic trait that is controlled by multiple genes? (Polygenic trait)

Polygenic trait is the term used to describe a genetic trait that is controlled by multiple genes. These traits often exhibit a wide range of phenotypic variation due to the combined effects of different genetic factors working together.

What are the four possible blood types in humans? (A, B, AB, O)

The four possible blood types in humans are A, B, AB, and O.

What is the difference between homozygous and heterozygous alleles? (Homozygous alleles are identical, while heterozygous alleles are different)

Homozygous alleles are identical copies of a gene, meaning they carry the same version (allele) of the gene from each parent, while heterozygous alleles are different copies of a gene, meaning they carry different versions (alleles) of the gene from each parent.

What is the probability of rolling a six on a fair six-sided die? (1/6 or 16.67%)

The probability of rolling a six on a fair six-sided die is 1/6 or 16.67%.

What is the purpose of a Punnett square in genetics? (To predict the potential outcomes of a genetic cross between two individuals)

The purpose of a Punnett square in genetics is to predict the potential outcomes of a genetic cross between two individuals by organizing and visualizing the possible combinations of alleles from each parent, enabling the determination of the probability of certain traits or genetic disorders appearing in offspring.

What is meant by the term "carrier" in genetics? (An individual who has a recessive allele for a particular trait but does not show the trait themselves)

A carrier in genetics refers to an individual who possesses a recessive allele for a particular trait but does not display the trait themselves due to also having a dominant allele masking its effects. Carriers can pass on the recessive allele to their offspring, potentially leading to the expression of the trait in future generations if the other parent also contributes a recessive allele.

What is the principle of independent assortment? (Genes on different chromosomes are inherited independently of each other)

The principle of independent assortment states that genes located on different chromosomes are inherited independently of each other. This means that the alleles of one gene segregate into gametes independently of the alleles for other genes, allowing for a greater variety of genetic combinations to occur in offspring.
