What is heterozygouz?
Many organisms contain two copies of each chromosome, and generally these two chromosomes are not identical. If a particular trait, such as the shape of a pea, is determined by one particular section of a chromosome, it is possible for the two copies of the chromosome to have different instructions for the trait. If the two sections of the two chromosomes have different instructions, this is called being heterozygous.Often if an organism is heterozygous for a trait, one of the sets of instructions (called an allele) will be dominant over the other. This means that if either of the chromosomes has that dominant version of the allele, that is the set of instructions that will be followed.Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r). A heterozygous plant would contain the following alleles for seed shape: (Rr).Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive. Using the previous example, round seed shape (R) is dominant and wrinkled seed shape (r) is recessive. Round: (RR) or (Rr), Wrinkled: (rr).
What adaptation is a physical trait that helps an organism to suvive or reproduce in its environment?
the adaption of life
Why do some bats have wrinkled lips?
my dear it is just the way they were made :l
What are the inherited traits of animals?
a inherited trait of a plant or animal is a trait (a characteristic or quality) that the plant or animal got from its parents! Same goes for humans! If you mom has blue eyes and you have blue eyes that is a inherited trait. Basically a characteristic passed down! Hope that heps! Good luck:)
What does ancestral trait mean?
a ancestral trait is a distinguishing feature that has been past on from a ancestor
Is round dominant over wrinkled?
Yes, in Mendelian genetics, the round seed shape trait is typically dominant over the wrinkled seed shape trait.
How did gregor mendel make sure that the plants with round seeds did not self pollinate?
He allowed plants whose seeds were round or wrinkled in shape to self pollinate. This trait has two variations-either round or wrinkled seeds.
What is the principle of dominance?
The Principle of Dominance states that some alleles are dominant and some alleles are recessive. The dominant trait dominates or presents the expression of the recessive trait. Thus, for round seed: (capital) R - round (small) r - wrinkled RR - pure round Rr - hybrid round rr - pure wrinkled
Two forms of the traits of seed shape in pea plants are?
Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.
How did Mendel make sure that the plant with round seeds did not self pollinate?
He allowed plants whose seeds were round or wrinkled in shape to self pollinate. This trait has two variations-either round or wrinkled seeds.
If a plant has round seed and the genotype Rr the ''r'' stands for what?
The little r stands for a recessive wrinkled trait.
How do you know that a pea plant with wrinkled seeds does not have one copy of the round seed allele?
The trait associated with the allele is not expressed in heterozygotes.
What is the genetic nature of wrinkled phenotype of pea seeds?
The wrinkled phenotype of pea seeds is due to a mutation in the gene that encodes for the starch-branching enzyme known as SBEI. This mutation causes a deficiency in the enzyme, resulting in the accumulation of unbranched starch in the seeds, which leads to the wrinkled appearance.
How did Gregor Mendel make sure that the plant with round seeds did not self pollinate?
He allowed plants whose seeds were round or wrinkled in shape to self pollinate. This trait has two variations-either round or wrinkled seeds.
What are the genes of a wrinkled pea plant seed?
The wrinkled seed is a round cell but has the ressivienie wrinkled seed in it.
What is the possibility that two heterozygous parents would have an offspring that produced round seeds?
In pea plants, the round seed trait (R) is dominant over the wrinkled seed trait (r). If both parents are heterozygous (Rr), the possible offspring genotypes are RR, Rr, and rr, with a 75% chance of producing round seeds (RR or Rr) and a 25% chance of producing wrinkled seeds (rr). Therefore, there is a 75% possibility that two heterozygous parents would have an offspring that produces round seeds.
Round seed shape in peas is an example of a trait controlled by a dominant allele beacause?
Round seed shape in peas is an example of a trait controlled by a dominant allele because the presence of even one copy of the dominant allele results in the expression of the round seed shape phenotype. This means that individuals with either two dominant alleles (RR) or one dominant and one recessive allele (Rr) will have round seeds, while individuals with two recessive alleles (rr) will have wrinkled seeds.
