Answer:
1/64
Explanation:
The following genotypes were crossed: AaBbCc X+Xr and AaBBcc X+Y
If we asume that the autosomal genes are in different chromosomes, then they will assort independently during meiosis and gametogenesis. In that case, we can use the Multiplication Rule of Probability to obtain the probability of having a specific genotype in the progeny.<u> This rule states that when two or more events are independent, the probability of all them happening at the same time will be the result of the multiplication of the individual probabilities of each event.</u>
<u />
We can separate each gene in the cross to determine the genotypic ratios in the offspring, and then multiply the probabilities of the aaBbCc X+X+ genotypes to obtain the overall probability of having progeny with that genotype.
<h3><u>Aa x Aa
</u></h3>
1/4 AA
2/4 Aa
1/4 aa
<h3><u>Bb x BB
</u></h3>
1/2 BB
1/2 Bb
<h3><u>Cc x cc
</u></h3>
1/2 Cc
1/2 cc
<h3><u>
X+Xr x X+Y</u></h3>
1/4 X+X+
1/4 X+Y
1/4 X+Xr
1/4 XrY
The probability of having offspring with the aaBbCc X+X+ genotype will be: 1/4 × 1/2 × 1/2 × 1/4 = 1/64
Multicellular organisms grow by producing more cells. As children, we get taller every year. That growth happens only because our bodies keep adding new cells. A sapling becomes a tree for the same reason.
But even after an organism grows up, its cells continue to divide. That's because cells wear out or get damaged.

I believe that most mature soils have three soil horizons. That is Horizon A, Horizon B, and Horizon C. Horizon A, also called the top soil contains a mixture of mineral matter and organic matter, as well as many insects, fungi, and microorganisms. Horizon B, also called the sub soil, contains fine clay particles washed out of horizon A. Horizon C contains partially weathered parent material.
Answer:
D.Moon's gravitational force.
Macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions , hope this helps :)
