Answer:
Each mutant would be mated to wild type and to every other mutant to create diploid strains. The diploids would be assayed for growth at permissive and restrictive temperature. Diploids formed by mating a mutant to a wild type that can grow at restrictive temperatures identify the mutation as recessive. Only recessive mutations can be studied using complementation analysis. Diploids formed by mating two recessive mutants identify mutations in the same gene if the diploid cannot grow at restrictive temperature (non-complementation), and they identify mutations in different genes if the diploids can grow at restrictive temperature (complementation).
Explanation:
Recessive mutations are those whose phenotypic effects are only visible in homo-zygous individuals. Moreover, a complementation test is a genetic technique used to determine if two different mutations associated with a phenotype colocalize in the same <em>locus</em> (i.e., they are alleles of the same gene) or affect two different <em>loci</em>. In diploid (2n) organisms, this test is performed by crossing two homo-zygous recessive mutants and then observing whether offspring have the wild-type phenotype. When two different recessive mutations localize in different <em>loci</em>, they can be considered as 'complementary' since the heterozygote condition may rescue the function lost in homo-zygous recessive mutants. In consequence, when two recessive mutations are combined in the same genetic background (i.e., in the same individual) and they produce the same phenotype, it is possible to determine that both mutations are alleles of the same gene/<em>locus</em>.
I believe its Uranus and Neptune, please tell me if I'm wrong.
Reason: an ice planet is made up of a semi icy surface like perhaps water, oxygen, or any other element stronger than hydrogen. Neptune and Uranus both meet this match, they are made up of elements that are actually stronger than hydrogen.
Answer:
Meat, fish and eggs.
Explanation:
Meat, fish and eggs are the foods that do not contain any or less carbohydrate, these foods are high in protein and fats. By looking on the nutrition label for the amounts per serving (in grams) of fiber and total carbohydrates, if there is no or less percentage of carbohydrates so by see the label we can say that whether the food has low or high amount of carbohydrates.
A population of frogs with
slightly different coloring is an example of microevolution. Microevolution is
the changes in the gene pool of a population that can be measured and observed in
short periods of time within a population. Microevolution can take place in
several ways such as gene flow, genetic drift, mutation and selection.
I would like to talk about a birthday celebration that I attended 2/3 months ago. It was one of my friends' birthday who turned 25 that day. My friend's name is Ryan and his parents wanted to celebrate his birthday just before his departure to United Kingdom. Ryan invited almost all of his close friends and 6-7 of us attended the birthday celebration together. Apart from us, there were as many as 100 other people present on the occasion. I did not know most of them but my guess is that they would be mostly Ryan's relatives, neighbors and his father's colleagues.
The party was celebrated at my friend's house at tohana. We went there together and bought a present for the Ryan. After reaching there, Ryan and his parents warmly welcomed us. Later Ryan introduced us to his relatives and to some of his neighbors. We were astonished when we saw the huge birthday cake. 25 candles of different colors were lit around the cake and the whole house was redecorated for the occasion. Anybody could say that some occasion was going on in this house without knowing anything.
We sang the birthday song when Ryan cut the cake. We congratulated him and wished him a prosperous life ahead. Then we ate cake and had a good feast. The foods were delicious and good. We, friends of our circle, went to visit a nearby place and sang different songs. In the evening we went to Ryan's house again and attended a raffle draw. That was a very exciting part of the birthday celebration. Then after few minutes we left the party and went our homes.
