Document Summary
Nuclei of all human cells except gametes contains diploid number of chromosomes (46), Two of the 46 chromosomes are sex chromosomes (x and y), determining genetic sex. Diploid genome, or genetic dna makeup, represents two sets of instructions one from the. The complete human karyotype is illustrated as follows: Matched genes, which are at the asme locus on homologous chromosomes, are called egg and one from the sperm alleles of each other. For genes within diploid cells: may code for the same or alternative forms of a given trait, both alleles are the same homozygous, alleles are different heterozygous. Sometimes, one protein product masks or suppresses the expression of its partner allele dominant allele, the allele being masked is said to be recessive. Dominant and recessive alleles do not interact at a genetic level: they each encode proteins, allele that encodes the protein that determines the phenotype is considered dominant.
