Answer:
Explanation:
Let "XB
" represents the dominant allele for no baldness
and let "Xb
" represents the recessive premature male-pattern baldness
Genotype of affected male is Xb
Y
Genotype of heterozygous female XB Xb
Now when the above male and female are crossed, the following offspring are produced
Xb
Y * XB Xb
XB Xb, XB Y, Xb Xb, Xb
Y
Since, this Xb allele is only expressed in males, therefore females will not be affected by it
Hence, out of 4 offspring only one male offspring with "XbY" genotype will have premature baldness
You didn’t put any of the choices for the risks, but I believe something important to consider is making sure that the tourists return the umbrellas.
We should use wind and solar energy more because those are the two main renewable energy sources, the sun shines a lot so we can use the power from that to power are houses, but at night that would be a problem, so at night you could use water as a renewable energy to power your house at night so you can get light, wind would be good if you live in a windy place like Cheyenne WY.
The correct answer is: 2.5%
The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.
• Telomeres-ends of DNA with protective role (prevents shortening of DNA),
• Non-coding RNA genes-e.g. genes for tRNA,
• Gene regulatory sequences such as promoter, enhancers and silencers.
Eukayotic cells spend most of their cell cycle in the interphase
