Answer:
1. 2.8%
2. 97.1%
Explanation:
- If the birth rate of this disorder is 1 in every 5000 births it means that the frequency of the recessive homozygous genotype is 1/5000=0.0002
If we name the gene for the disorder with A, than the genotypes are aa (homozugous recessive), Aa (heterozygous, carrier), AA (dominant homozygous).
According to the Hardy-Weinberg equation:
frequency of AA is p2 (P)
frequency of Aa is 2pq
frequency of aa is q2 (Q) and
p2+2pq+q2=1 (P+Q=1)
Q=0.0002 P=1-0.0002=0.9998
q= 
0.0002=0.014
p=0.9998=0.999
2pq=0.028=2.8%
2. According to the Hardy-Weinberg equation:
frequency of AA is p2 (P)
frequency of Aa is 2pq
frequency of aa is q2 (Q) and
p2+2pq+q2=1 (P+Q=1)
The frequency of the recessive homozygous genotype (Q) is 1/5000=0.0002
Q=0.0002
q2=0.0002 2pq=0.028 p2=?
p2= 1-0.0002-0.028 =0.9718=97.1%
DNA is organized into chromosomes. The organisms genome is the DNA in all their chromosomes.
During meiosis, the process that creates eggs and sperms, homologous chromosomes line up and recombine, meaning their sequences get mixed up together to form new chromosomes. One of each of these new chromosomes is independently assorted into daughter cells, so that each egg and sperm contain only one chromosome necessary (1n). When the sperm combines with the egg, the zygote (new organism) contains a copy of a homologous chromosome from each parent (2n).
Answer:
Large bodies of water take more time to change temperature than land.
Explanation:
Large bodies of water take more time to change temperature than land because more energy is required by water to in order to make the water evaporate, therefore, water takes more time to change its temperature as compared to the land. Water also has a particular temperature which takes more time in order to be changes. Land is not transparent, therefore, heat or cold has no need to be get penetrated in it, whereas, water is a transparent medium where heat and cold is required to get absorbed till its deep end, so it takes more time for water to change its temperature as compared to land.
