A hypertrophied left ventricle is a echocardiographic sign that there is chronic stress put in the left ventricle, most commonly in overcoming high aortic pressures in patients with systemic hypertension.

In leghorn chickens colored feathers are produced by a dominant allele,
Gnesinka [82]
<span> Basically the male will have CC, the hen will have cc, and neither of them will have I. The key thing is that _all_ the chicks are coloured.

The male must have at least 1 C to be coloured, and cannot possess the dominant I. The hen has cc and/or an I to not be coloured.

That one chick is coloured would tell you little - only that the hen couldn't have 2 inhibitor alleles because otherwise the chick would have to have one and it doesn't.

However, for all of many chicks to be coloured, that means that the hen can't have any inhibitor alleles (otherwise around 50% would be white for that reason alone).

So to be colourless, the hen must be cc. However, if the male had only 1 colour allele (ie it was Cc) that would still mean that 50% of the chicks would be Cc (daddy's 'c' and one of mummy's 'c's). 

Hope this helps please award brainly :)
