Answer: Thermal energy refers to the energy contained within an object that changes its temperature. Heat is the energy of thermal energy. A chemical change happens when one substance and another substance form into two or more different substances.
Answer: 100% will be heterozygous green.
Explanation:
Since both parents (green and yellow) are homozygous and green is dominant, when they are crossed all the resultant offsprings will have both genes of green and yellow in their genotype but will appear as green( phenotype) because the green colour is dominant and has masked the yellow colour which is recessive.
Divide the amount in half for every 2 minutes
0 minutes = 20 grams
2 minutes = 20/2 = 10
4 minutes = 10/2 = 5
6 minutes = 5/2 = 2.5
8 minutes = 2.5/2 = 1.25 grams
Answer: When genes found on different chromosomes, said to be not linked.
When genes seen close together on the same chromosomes said to be linked.
Explanation:
(a)
According to Mendel’s law of independent assortment, when genes located more than 50 map units and found on different chromosomes as far apart on the same chromosome so they divide independently and obviously said as not linked.
(b)
It is found that when genes located and seen tightly close together on the same chromosome, known to called as Linked which means that alleles or genes look close together on the same chromosome can be inherited afterwards as a unit frequently than not. For instance, when two genes are linked and become tightly close together by using data from genetic crosses lead to calculate recombination frequency as well.
Similarly, when we finding recombination frequencies for more than one gene pairs, can make linkage maps among them that finally show the relative distance between them.
