welcome to moomoomath and science in this video i'd like to talk about genotype first phenotype your genotype is your genetic code of your cells this genetic code is responsible for many of your traits the physical expression of your genotype is your phenotype your genetic information is stored in your chromosomes on sections called genes a gene is a portion of dna that codes for a tree the following picture illustrates this if you look at this drawing of a gene the different sections are your genes in genetics you'll encounter three types of genotypes homozygous dominant homozygous recessive and heterozygous you get some information from mom and some information from dad the different forms of the same traits are called alias take a look at the different hair texture these different forms are alias it is still hair just different forms a dominant allele will cover up or mask a recessive allele you will only get a recessive allele if both alleles are recessive your phenotype is the actual expression of the genotype for example this dog has a round nose this cat has black hair these are physical expressions of the genetic code hope this helps with genotype versus phenotype and moomoomath uploads a new math and science video every day thanks for watching please subscribe and share
