The trait for red hair is recessive, meaning that when a person expresses two copies of this allele they have red hair. what can
AlekseyPX
Let "r" stand for the recessive red hair trait. A person with red hair must have a genotype of "rr" ( one from each parent) in order to have red hair( red hair being the phenotype).

Let "B" stand for brown hair and "b" stand for not brown hair. A person with brown hair can have a genotype of "Bb" or "BB" and have a phenotype of Brown hair. This is becasue brown hair "B" is the dominant trait.

Mendel crossed plants that produced only round seeds to those that produced only wrinkled seeds. In the next generation, all the
Artist 52 [7]

Answer:

Dominance

Explanation:

Mendel discovered certain principles that governs heredity or inheritance when he conducted experiments. In his experiments, he discovered that an organism receives two copies of a gene called allele, from each parent.

He discovered that one allele of a gene has the ability to mask or suppress the expression of its allele variant in the same gene. He called the allele that masks or is expressed, DOMINANT allele, while the allele that is masked, RECESSIVE allele. Based on this observation, he named his first principle, LAW OF DOMINANCE.

In this case, he crossed a purebreeding round-seeded pea plant and a purebreeding wrinkled-seeded pea plant, he noticed that in the F1 generation, all the offsprings possessed round seeds. This led to the conclusion that the allele for round seeds masks the phenotypic expression of the wrinkled allele in a heterozygous state. Hence, the allele for round seeds is dominant while the allele for Wrinkled seeds is recessive.
