Answer 1

Answer:

Answer 2

Answer:

A cell is said to be homozygous for a particular gene when identical alleles of the gene are present on both homologous chromosomes.[2] The cell or organism in question is called a homozygote. True breeding organisms are always homozygous for the traits that are to be held constant.

Heterozygous Edit

A diploid organism is heterozygous at a gene locus when its cells contain two different alleles (one wild-type allele and one mutant allele) of a gene.[3] The cell or organism is called a heterozygote specifically for the allele in question, and therefore, heterozygosity refers to a specific genotype
