What are some example of dominant and recessive traits in humans?
Dwarfism is a dominant trait in humans.
What are some patterns of humans inheritance?
Autosomal dominant Autosomal recessive X linked recessive.
What are some patterns of inheritance in humans?
Autosomal dominant Autosomal recessive X linked recessive.
Are ears that point outwards the result of dominant or recessive genes in humans?
Yes
What are the two different alleles for a gene?
I think it is Dominant and recessive.
Blood type in humans is determined by a single gene that has multiple alleles?
Each person has two alleles for their blood type, one dominant and one recessive. Except for type AB blood where the alleles are co-dominant. The allele for O blood is always recessive when paired with either an A or B allele.
Is green eye color a recessive trait?
Green and blue eyes are caused by the same gene. So neither would be dominant over the other.
Is there a relationship between the frequency of a trait in a population and whether that trait is dominant or recessive?
Some observable traits in humans are dimples, earlobes, tongue-rolling, cleft chin, hairline, and freckles. The relationship between the frequency of a trait in a population and whether the trait is dominant or recessive because in inherited human traits, the offspring can either have dimples or no dimples.
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?
Recessive allele is more common or dominant allele?
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.
Can both dominant and recessive traits be expressed?
If by "all dominant phenotypes" you mean the parents are homozygous, then no. AA x AA will never yield a gamete with AA But if you're talking about heterozygous chromosomes Aa x Aa, then yes
What are the differences between alleles and genes?
An allele is a form of a gene. Basically, in simple Mendelian genetics, there are two genes that can be expressed: the dominant form and the recessive form. A pea plant can be tall (dominant) or short (recessive). If a plant is tall, what controls that tallness is a gene. The fact that it is tall is due to the presence of the allele. ----------------------------------------- Simple improvement: The gene locus is the position on the chromosome that controls a specific trait (e.g. colorblindness). Alleles are different genetic sequences that can occur at that position to give a specific trait (colorblind, not colorblind). Since in humans there are two gene loci for each trait (one from mother and one from father), alleles can either be dominant-recessive (recessive only expressed when dominant is absent), codominant, or incompletely dominant, etc.
