Answer:
1. 128
2. 16,384
Explanation:
Imagine there were two pairs of chromosomes:
A paired with B
C paired with D
A gamete could have the following combinations:
A + C
A + D
B + C
B + D
Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities
With seven pairs of chromosomes, there are (2⁷) possibilities. 2⁷ = 128
For a zygote produced by two barley parents, there are two gametes fused. So we must multiply the number of combinations for each gamete. Therefore, number of possible genetic combinations is 128 x 128 = 16,384
Answer:
It began after the stock market crash of October 1929, which sent Wall Street into a panic and wiped out millions of investors. Over the next several years, consumer spending and investment dropped, causing steep declines in industrial output and employment as failing companies laid off workers
<span>When the phenotype of a heterozygous is intermediate between both homozygous, the pattern of inheritance is incomplete dominance.</span>
<span>The battery which Ryan kept in fridge, assuming it was well protected from any moisture or water, it would tend to play the CD longer than the one stored in a desk drawer. This is because storing batteries in a cool dry location while protected from any moisture or water, can help to prolong shelf life. This is due to the fact that low temperatures tends to slow down the electric current flow within the electrolyte fluid inside the battery, hence, the rate of power dissipation is reduced thus slowing down of the power drain from battery by the electric current flow .
Thus, the battery stored in the fridge tends to have lost less power, if any, compared to the one stored in a desk drawer.</span>
