Are Freckles are a physical trait that is transmitted by a recessive gene?
Freckles are a physical trait that is transmitted by a recessive gene?
Which term describes the example below- A child with no freckles has a mother who has freckles and is heterozygous and a father who has no freckles and is homozygous recessive?
We'llsay F is dominant for freckles and f is recessive for non-freckled. The father is ff The mother is Ff The child is ff. Probability of this cross producing a homozygous recessive child is 50%. There isn't a precise term for this cross.
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
Is vulcan dominant or recessive?
The Vulcan is the dominant expression.The earthling sign is recessive.
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
Are Freckles are a physical trait that is transmitted by a recessive gene?
Freckles are a physical trait that is transmitted by a recessive gene?
Having freckles is dominant (F) and not having freckles is recessive (f). A mother has Ff and a father has ff. If they have a child which genotype will make their child not have freckles?
ff (apex)
Can someone give you a List of dominant or recessive personality traits?

What One recessive and one dominate allele?
A dominant allele could be right handedness, or a straight hairline. A recessive allele could be freckles, a widows peak, clef chin, or left handedness.
What can be dominant or recessive?
Alleles can be dominant or recessive
Are freckles recessive genes?
Freckles are not determined by a single recessive gene. They are the result of a combination of genetics, particularly the presence of certain variations in the MC1R gene, and exposure to sunlight. The inheritance of freckles can vary depending on the specific genetic traits passed down from parents.
What is an example of recessive human trait?

Is melanoma dominant or recessive?
is malignant melanoma dominant or recessive
A man with freckles and a women without freckles with 3 kids with freckles and 1 without what is the genotypes of the parents and children?
The man must have a dominant gene for freckling and a recessive gene for no freckling. The woman has both recessive genes for no freckling. Therefore, there should be a 50% chance of getting the freckling gene and freckle in this family. If they had more children, chances are 50/50 that the baby will freckle.
