It is called a Punnett Square
Yes and no. Everyone's heart works the same way, is made of the same type of tissue and is located in the same part of the body. However, there are people with diseases who have hearts that are in worse condition and may look different. For example, people with coronary artery disease experience plaque build up in their coronary arteries, which causes a reduction of blood flow to the heart, and in order to treat this they may get a bypass surgery in which another blood vessel from somewhere else in the body, would be used to bypass the blocked blood vessel. In this case the anatomy of that person's heart would be slightly different.
Answer: true..? idrk tbh srry!

If the sediments are being moved, it's erosion
Answer:
Let the "barred" allele be caller B and the "non-white" allele b. Since chickens use chromosomes and to determine sex, hens would have chromosomes , and roosters would have chromosomes . A Z-linked gene is represented as a superscript on the chromosome, for the dominant allele and for the ressesive allele.
A barred hen would have a copy of B on its Z chromosome, a non-barred rooster would have both copies of b on both Z chromosomes. Using Punnet squares to represent the crosses we get the following cases:
That is a ratio of two barred heterozygote roosters to two non-barred hens. Crossing them we get:
That is a ratio of one barred heterozygote rooster to one barred hen to one non-barred rooster to one non barred hen.
