In gametes generated by F1 tri-hybrids and gametes produced by parents from true-breeding populations.
When non-sister chromatids of homologous chromosomes exchange genetic material during meiosis, novel allelic combinations are created in the daughter cells. The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. When F1 progeny are self-pollinated, a 3:1 ratio of F2 progeny are created.

Answer:
3:1
Explanation:
To find out the phenotypic ratio, we need to do a Punnet Square.
We know that R and I are the dominant alleles that produce red flowers, and r and i are the recessive traits.
<u> ║R ║ r</u>
<u>I ║RI║Ir</u>
<u>i ║Ri║ir</u>
The genotype ratio would be 3 because the dominant traits are present three times (RI, Ir, and Ri) and 1 for the recessive trait since it only appears once in the Punnet Square (ir). In conclusion, the phenotypic ratio form the roses are 3:1
You use the mRNA to make amino acids.
Hi there!
In order to do fossil comparative anatomy and branching diagrams to explain the evolution of organism, scientists use <u>radiocarbonation </u><u>method</u>.
Explanation:
Carbon-14 can combine with oxygen in the atmosphere to create carbon dioxide, which is then absorbed by plants and makes its way through the food chain. The amount of carbon-14 in living plants and animals matches the amount in the atmosphere, but when plants and animals die, they no longer absorb carbon-14.
Because radiocarbon has a known rate of decay, the scientists can now determine about how long it has been since the plant or animal was alive. <u>The lower the amount of radiocarbon, the older the object.</u>
(Sometimes, C-12 is also used)
