a. It happens when two or more alleles control the inheritance of a character.

b. It refers to traits that are controlled by genes located on the same-sex chromosomes.

c. It occurs when two dominant alleles of a contrasting pair are fully expressed at the same time in a heterozygous individual.

d. It occurs when the phenotype of the offspring is somewhere in between the phenotype of both parents.

Circle the letter of each sentence that is true about alleles. a. Recessive alleles are never present when dominant alleles are present. b. Alleles are different forms of a gene. . c. Dominant alleles?

The true statements about alleles are: b. Alleles are different forms of a gene. Recessive alleles can be present alongside dominant alleles; they are simply masked by the dominant ones. The statement about dominant alleles is incomplete, so it cannot be evaluated as true or false.

True or false even if a gene has alleles a person cannot have more than three of those alleles?

True. A person can have at most two alleles for a given gene, one inherited from each parent. While a gene can have multiple alleles in the population (more than two), an individual can only possess a maximum of two alleles at any specific gene locus.


When more than two different alleles control a trait?

This phenomenon is known as multiple allelism, where there are more than two different variations of a gene (alleles) that can affect a single trait. In this case, individuals can inherit one of several possible alleles for the trait. Examples include the ABO blood group system in humans, where there are three alleles (IA, IB, i) that determine a person's blood type.


Is the following statement true or false only pea plants that have two recessive alleles for short stems will be short?

False. Pea plants can have short stems if they have two recessive alleles for short stems, but they can also have short stems if they have a combination of dominant and recessive alleles that result in a short stature.
