natural selection
In a heterozygous offspring, the recessive allele is present but not expressed because the dominant allele masks its effects.
This is known as Mendelian inheritance, where each parent contributes one allele for a trait to their offspring. This process follows Mendel's principles of segregation and independent assortment.
A dominant allele is expressed when an individual carries one or two copies of that allele. A recessive allele is only expressed when an individual carries two copies of that allele. Dominant alleles are typically passed on to offspring if at least one parent carries the dominant allele.
Allele
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
If one parent is homozygous recessive for a trait, all of their offspring will inherit one copy of the recessive allele. Therefore, 100% of the offspring will inherit the recessive allele from a homozygous recessive parent.
The offspring will get the traits of Homozygous BB .
One copy of each allele, resulting in the offspring having one dominant allele and one recessive allele. This combination is known as heterozygous.
Let's see what combinations can be formed.HH, HH, Hh, Hh.So, yes their offspring can contain the recessive allele.(THe offspring can be a carrier of the recessive allele.)However, since it is impossible for the offspring to be homozygous recessive,the recessive trait/gene will not show in the offspring's phenotype.Hope that helps!
R represents the dominant round allele, and rrepresents the recessive wrinkled allele. :D
