All organisms are grouped into five kingdoms. Those are Monera, Protoctista, Fungi, Plantae and Animalia. The division is made based on 3 criteria. Those are cellular organization, arrangement of cells, and type of nutrition. Cellular organization is whether they are eukaryotic or prokaryotic. Cell arrangement is whether they are unicellular, multicellular, with or without true tissue differentiation etc. Type of nutrition is whether they are autotrophic or heterotrophic. Kingdom Protoctista includes algae, protozoans, oomycota and slime moulds.
<span>Roan is a combination of white hairs with red hairs. When we see cattle like this, they look pink because it resulted from a mix of white and red.
Red allele: A
White allele: a
</span>
<span>A heterozygotic animal has this genotype: Aa
Like i said previously this is the mixture of colors so the animal would be pink.
A red coat color has this genotype: AA
A white coat color has this genotype: aa
To get all the herd to be</span><span> roan-colored cattle the combination of parents should be: AA x aa. -> 100% roan
Another possible way to obtain would be</span><span>roan-colored cattle: Aa x Aa or aa x Aa (in this case there would be less probabable to obtain road).</span>
