He used Selective Breeding
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>
<em>Cone-Bearing Plants</em> also known as <em>Conifers, </em>are classified as Gymnosperms
<span>They are considered accessory glands of the digestive system because they only send digestive juices and acids to the main digestive organs. Food does not actually enter any of the accessory organs.</span>
Yes indeed it is, I actually didn’t know that tho
