What is the scientific name for freckle?
The scientific name for freckles is ephelides. They are small, flat, tan or light brown spots that appear on the skin as a result of sun exposure.
How much DNA do humans share with cats?
Humans and cats share about 90% of their DNA. The genetic similarities are evident in various aspects, such as the structure and function of certain genes controlling traits like metabolism and immune response.
How do genes control variation within a species?
Genetic variation occurs through random gene mutation all the time and espescially during meiosis where different allele combinations occur through the formations of chiasma in prophase and as part of random separation in anaphasethis will create a unique arrangement of genetic variations in the genotype which will be presented, naturally, through the phenotype
What is it called when the genotype becomes expressed as phenotype?
This is called gene expression, where genes are transcribed and translated into proteins, leading to the manifestation of specific traits in an organism.
Which groups is the smallest level of classification?
The smallest level of classification is a species. It is the basic unit of classification and represents a group of organisms that are capable of interbreeding and producing fertile offspring.
Are freckles dominant recessive or dominant dominant?
Freckles are considered a dominant trait, as they are caused by a dominant allele. This means that individuals only need to inherit one copy of the allele from either parent in order to have freckles.
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.
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.
Do dominant genes affect recessive genes?
The dominant genes take over, and then the recessive genes hide away
Which genes are dominant and which are recessive?
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
Could A man and women with no freckles have a child with freckles?
Yes it depends on their genes
What genes does a homozygous short pea plant always have?
Recessive genes
What do you call oransim that posssses two dominant or two recessive genes for a single trait?
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
Can recessive genes become dominant?
Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
Can two parents who do not have freckles have a child with freckles?
Yes, if they both carry a recessive (hidden gene) for freckles, then yes their child would have a 25% chance of having freckles.
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)
If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?
The offspring will all have one dominant and one recessive gene for the trait, making them carriers of the recessive gene while displaying the dominant trait.
