Alleles for a specific trait are found only on homologous chromosomes.Group of answer choicesFalseTrueNext

A ______ individual has two identical alleles for a gene.Multiple choice question.hemizygousheterozygoushaploidhomozygous

Alleles _____.Group of answer choicesaffect the same trait.are alternate forms of a gene.have the same position on a pair of chromosomes.Next

The ______ is the combination of alleles an individual has for a particular gene.Multiple choice question.phenotypeallelotypegenotypechromotype

Choose statements that correctly refer to components of Mendel's model of inheritance (please note that the answers use the modern term gene instead of factor).Multiple select question.Alternative forms of genes are called alleles.Parents transmit genes to offspring.The presence of an allele doesn't ensure that it will be expressed.The two alleles remain discrete.Each individual receives two copies of each gene from each parent.The two alleles are usually the same.
