Dominant Alleles
What do Dominant alleles do.
If a child inherits the gene, then it'll be the gene that shows.
What do recessive alleles do?
They can be considered hidden genes because they can lay dormant unless the other parent has the same gene.
What does an incomplete dominant allele do.
It partially masks the recessive alleles instead of fully masking it.
Is it possible for a female to have Y chromosome?
No
Is a person has two X chromosomes, what does this mean?
This means the person is biologically female.
How are dominant alleles represented on the Punnett square.
With capital letters.
What is the number of recessive alleles for a trait to be expressed?
Dos
How many incomplete dominant alleles are needed to express the trait.
Uno
Are Y chromosomes slower than X chromosomes?
Yes, since they are larger, Y chromosomes are slower.
What parent always gives the X chromosome?
The mother gives the X chromosome always.
Can dominant alleles produce a new, different, or poorly timed protein, overpowering the normal one?
Yes
Are recessive alleles crucial in finding inherited disorders with two faulty copies.
Yes bro
What is something useful dominant alleles do.
They allow organisms to express beneficial traits with only a single copy of the gene
What specific gene does the Y chromosome carry that the X chromosome rarely carries?
The SRY chromosome
Why do females have two X chromosomes?
They are necessary for development in females.
What happens when an allele is dominant
It produces a dominant phenotype in individuals who have one copy of the allele.
The trait hidden for recessive alleles
True
What is incomplete dominance in alleles?
It is a genetic pattern where neither allele for a trait completely masks the other in a heterozygote
Does the Y chromosome have fewer genes than the X chromosome?
The Y chromosome has significantly fewer genes than the X chromosome or other autosomes.
Is the X chromosome more dense?
Yes
A dominant disease, is it considered common or uncommon?
Uncommon, because there are unlikely percentages for dominant diseases to happen.
What is the term for someone who has a recessive allele but doesn't show the trait?
Why does incomplete dominance occur?
It occurs when there is a blending between two homozygous phenotypes.
Is the Y chromosome useful for studying male-specific health?
Yes it is, this is because its unique direct father-to-son inheritance.
Why is one of the two X chromosomes in females largely silenced?
Gene balance.
