What is the difference fom heterozygous and homozygous recessive?
In genetics, you can either have a dominant allele (A) or a recessive allele (a). Being homozygous means that you have both of either a dominant or a recessive allele (ie you are either AA or aa). If the trait is a recessive trait, then you need to have it be homozygous recessive in order to express that trait. Hope this was helpful! :-)
How selective breeding using dominant principle can positively affect Belgian Blue Cow?
It depends on what trait is being selected for. Whatever that trait is, it has to be a trait that will improve the BB breed, not unimprove it. How that works is that purebred cattle are selected for a dominant desirable trait and bred together to produce more cattle with that trait. Any other cattle that have the recessive undesirable trait are culled.

Down syndrome is neither dominant nor recessive. Actually, it is considered to be an "autosomal" trait. This occurs when there is damage to the chromosome.
What is an autosomal dominant disorder?
Chromosomes can be divided into autosomes and sex chromosomes. The sex chromosomes (eg X and Y in humans) carry genes concerned with sex determination. The remaining chromosomes are called autosomes. They carry genes which are the same in males and females. Aberrations are changes or mutations in the chromosomes. So autosomal aberrations are mutations in the non-sex chromosomes.
