Gregor Mendel crossed homozygous tall plants (TT) with homozygous short plants (tt). All the resulting offspring were tall. From these results, what conclusion did Mendel draw? a)Tallness is a dominant trait. b)The word homozygous always means dominant. c)Only dominant alleles are passed on to offspring. d)The alleles of the offspring were recessive.
Answers
And all the plants would be heterozygous which means all of them will have Tt.
As we know that all offsprings were tall, We can conclude that tallness is a dominant trait
So the answer would be A).
Answer:
Explanation:
Definition of homozygous:
a gene region where there are two identical alleles present. Two alleles with the same variation or two alleles that are normal can both be present in a homozygous genotype.
Definition of heterozygous:
a gene region where there are two distinct alleles present. One normal allele and one mutated allele, or two distinct mutated alleles, can make up a heterozygous genotype.
Definition of homozygous dominant:
When an organism is homozygous, it contains two copies of the same allele for a gene. When two copies of the same dominant allele or two copies of the same recessive allele are present in an organism, it is said to be homozygous dominant or homozygous recessive.
Conclusion of Mendel draw:
As a result of having one "T" allele, each progeny is a tall plant. This is so that a plant with one "t" allele and one "T" allele will only exhibit the properties of the "T" allele, which in this case is a tall pea plant, since the "T" allele is dominant over the "t" allele.
Homozygous tall plants (TT) and homozygous short plants were crossed by Gregor Mendel (t t). The children that were produced were all tall. What inference did Mendel make in light of these findings? Tallness is a dominant characteristic.
