Static friction this should help :)
Explanation:
When analyzing two linked genes there are 2 possibilities: either there is recombination between them during meiosis or there is no recombination. Crossing over happens during meiosis I, when each chromosome has two sister chromatids.
If no recombination happens, the 4 resulting gametes will be parental.
If recombination happens, 2 gametes will be parental and 2 gametes will be recombinant. For that reason, the maximum recombination frequency between two genes that can be calculated is 50% (recombination frequency = recombinants/total).
1. uracil (U) is dna and thymine T is mRNA
2 is an opinion
3 i think polymerases in rna
Their unique combination of genes
<span>The energy or chemical that impinges upon and activates a sensory receptor is known as a "stimulus".
A major part of sensory receptors is to enable us to find out about nature around us, or about the condition of our inner condition or environment. Stimuli from fluctuating sources, and of various sorts, are gotten and changed into the electrochemical signs of the nervous system. This happens when a stimulus changes the cell film capability of a sensory neuron.
