Believe it or not, 99.9% of the species on Earth have gone extinct. Now, not all of these were caused by Humans, some were caused by MAJOR cataclysmic events such as the extinction of dinosaurs or other prehistoric animals that make up a large amount of the species on Earth. And remember that all the prehistoric plants are also included, because every plant organism is ALSO a species.
Hope this helps, if not, comment below please!!!
The answer is <span>Conduct a test cross with a purebred recessive plant.
</span>
Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>
If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.
<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>
If D is dominant and d is recessive
1. Dd
2. DD
3. dd
Answer:
Plants
Explanation:
They are multicellular organisms. In plants there are two types of reproduction :- sexual and asexual. Sexual reproduction happens when androecium and gynoecium both fuses and in asexual reproduction when only androecium or gynoecium is present in a plant. Androecium us a male part off flower and gynoecium is the female part of flower. Plants can't move that we all know and they are autotrophs coz they can make their own food in presence of sunlight, water, air and chlorophyll.....
I hope u will understand it :-) :-)
