Perhaps the bird’s calls could be less attracting and disorienting to predators and the ones with the said distinctive calls could have survived to repopulate and pass down the genes.
The answer is false <span>The reason why main heart failures and blood vessel clottage is mainly caused by the accumulation of lipids specifically bad cholesterol. </span>
<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>
Ants and bee's don't have a backbone, instead, in most cases, they have an exoskeleton.
Hope this helped:)
