ff (apex)
What else can I help you with?
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)
What genotype is homozygous?
A homozygous genotype refers to having two identical alleles for a particular gene. It can be either homozygous dominant (two dominant alleles, such as AA) or homozygous recessive (two recessive alleles, such as aa).
Apply the term homozygous heterozygous dominant or recessive to describe plants with the genotypes PP and Pp?
== == ---- I don't get it... - pyroactive == == == == == == == == == == == ==
What prepesents a heterozygous genotype?
A heterozygous genotype represents having two different alleles for a particular gene, with one being dominant and the other recessive. This results in the individual expressing the dominant trait while also carrying the recessive allele.
Are Freckles are a physical trait that is transmitted by a recessive gene?
Yes, freckles are a physical trait that can be determined by genetic factors. The development of freckles is influenced by a combination of genetic predisposition and exposure to sunlight, rather than being solely determined by a single recessive gene.
What is it called having a dominate and recessive allele?
Having a dominant and recessive allele is known as Mendelian inheritance, named after Gregor Mendel, the scientist who first described it. In this type of inheritance, the dominant allele masks the expression of the recessive allele in heterozygous individuals.
What is the difference between homozygosity and heterozygosity?
Homozygosity refers to having two identical alleles for a particular gene (e.g., both alleles are dominant or both are recessive), while heterozygosity refers to having two different alleles for the same gene (one dominant and one recessive allele). In homozygosity, an individual's genotype is either homozygous dominant or homozygous recessive, whereas in heterozygosity, the genotype is a combination of both dominant and recessive alleles.
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 does pure dominant mean?
"Pure dominant" refers to a genetic trait that is consistently expressed when a specific allele is present in an individual's genotype. In inheritance patterns, a pure dominant trait will mask the presence of any recessive alleles in the same gene.
What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype
What is it when you have a gene pair that consist of two dominate alleles and two recessive alleles?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
