Is a haploid homozygous ?
Very different between heterozygous and monozygous… Homozygous is the geneotype (combination of the pair of alleles) where both alleles are the same (recessive and recessive or dominant and dominant) Heterozygous is the genotype where both alleles are different (recessive and dominant). Monozygous is where the embryo divides to produce two identical diploid cells and thus produces identical twins. Diploid describes a cell with pairs of chromosomes (i.e. a body cell) Haploid describes a cell with one chromosome per ‘pair’ (i.e. sex cells) Remember – an allele is a form of a gene. Both chromosomes in a pair code for the same genes but each gene can be of a different form (allele) and still code for the same characteristic (but the combinations give different outcomes of the characteristics). Alleles are normally of two types – dominant and recessive – but sometimes there can be more than two possible alleles.
