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! :-)
Autosomal recessive alleles ( both males and females) and X-linked alleles in females always express themselves in homozygous condition. On other hand, X -chromosome linked recessive allele express singly in males.
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.
This means that a trait which is expressed is between the dominant and recessive genes. This means both alleles are partially expressed.

recessive
A trait that masks another trait is called dominant, or a dominant trait.
It is a recessive trait
When two recessive genes are inherited, and the portion of recessive inheritance is 51% or greater in favor of the recessive trait.
A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
A recessive trait is a trait that is not dominant, and is not really seen in ones phenotype.
The recessive trait isn't present when the dominant form of the trait is there. Whenever a trait is dominant trait is present it ALWAYS takes over the recessive one. the law of Dominance

dominant
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
