Is it true that if you have a male baby it means the mothers genes were stronger and more dominant?

No this doesn't necessarily mean that the fathers genes were dominant. Although the father does determine the sex of the baby this doesn't mean that he genes would be more prominant. yes, because a woman has two little y's and a man can have too big Y's to make a girl or two big X's or a big X and a little Y to make a boy. The male sperm contains the genetic code for sex.

What does the notaion Dd mean to genetics?
The notation Dd means that out of an allelic pair on gene D is dominant and the other d is recessive. The organism containing such configuration of genes are called heterozygote.
If both parents have blond hair and blue eyes will ther baby have the same?
Each person have 2 genes for almost all characters we own. Blond hair and blue eyes are traits that are determined genetically by recessive gene variants. Such genes can express only in the absence of the dominant genes (in this case the genes for black/red hair or dark/green eyes). The dominant gene always suppresses the recessive ones. So If both parents have blond hair and blue eye, thus none of them posses dominant genes, it means that their offspring cannot show a dominant character, and yes he/she will also have blond hair and probably blue eyes. Probably blue, as for eyes the grey color is more recessive then blue, and parents might carry its gene as well.
Why are recessive genes more common?
Sometimes there are more dominant genes than other genes so you will notice them earlier, but generally not more common. Genetic mutations are passed on by the parents so that the child can continue it. It more common that the parent can obtain the mutation and it is very common that the mutation will be passed on to the Evolution, Spontaneous Generation, Biogenesis, Sexual Reproduction?
How do you use recessive allele in a sentence?
The building blocks of our genes (that make us what we are) are called alleles and these can be either dominant, recessive or codominant - which means they are equally dominant. Now for your sentence: "A typical example of codominance can be found in blood types, where the existence of A as well as B alleles in a person will lead to blood type AB".
What are examples of recessive traits and dominant traits?
That's strictly a human view point. In fact there is no such difference, you just have two different proteins (one from each gene) which have behaviors relative to each other. How we (us, people) interpret the somatic result of the competition between them is labeled "dominant or recessive". For example - assume one form is totally non functional, then the somatic result would be classed as recessive.
What does pure dominant mean?
Pure dominant = two dominant genes that make a "pure dominant" trait. Pure Recessive = two recessive genes that make a "pure recessive" trait.
Why liger and tigon have these name?
Liger means that the lion genes are more dominant because the lion part of the name comes first (li), While tigon means the tiger genes are more dominant, as the tiger part comes first (tig).
What makes dominant alleles different from recessive alleles?
It's in the word! Dominant means bigger or stronger or greater. So the dominant allele is the stronger gene that is going to show whereas the recessive allele is still in you, but is overshadowed by the dominant allele.
What does incomplete dominan ces mean?
This means that a trait which is expressed is between the dominant and recessive genes. This means both alleles are partially expressed.
What is the difference between dominant and recessive gene?
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
Is the genotypeAA a homozygous dominant or heterzygous dominant?
The two AA genes are the same uppercase letter, so they are homozygous. 'Homo' means 'same'. If the genotype was Aa, it would be heterozygous, because 'hetero' means 'different'.
What does it mean to be homozygous dominant heterozygous or homozygous recessive?
Homozygous means "same" so a homozygous recessive trait would be a same [with parents] trait that is not the stronger trait which is dominant. Dominant is stronger showing trait, recessive is weaker trait. If you are dealing with Punnett squares then tt is homozygous recessive and TT is homozygous dominant. Hope this helped...
Father with homozygous genes for dominant trait?
This means that the father has two copies of the dominant allele for a particular trait. As a result, all of his offspring will inherit at least one copy of the dominant allele from him. This implies that all his offspring will either express the dominant trait or be carriers of the dominant allele.
Genes that always show themselves are called?
There's not exactly a clear-cut way to answer this. If someone is homozygous dominant, that means they have two dominant genes, AA for example, and, of course, the dominant phenotype (phenotype just means the physical expression of a trait/gene) will be expressed. If someone is homozygous recessive, meaning they have two recessive genes, aa, they would then express the recessive gene. Now, in cases of complete dominance and a person with a heterozygous genotype (Aa), the dominant gene will always show itself, which is probably the answer you were looking for. Be careful not to generalize too much, it's an easy way to get tripped up on tests.
What are different recessive traits and dominant traits?
I think you mean to ask what is the difference between RECESSIVE and dominant traits. Simply put, recessive means weaker, dominant means stronger. Every person has 23 pairs of chromosomes. We get 23 chromosomes from our mother and 23 chromosomes from our father. The chromosomes contain genes, which code for our traits - hair colour, eye colour, nose, height etc etc. When the chromosomes join, there can be 3 results: 1). two recessive traits, e.g two genes for blue eye colour 2). one recessive and one dominant traits, e.g one gene for blue eyes, one gene for brown eyes 3). two dominant traits, e.g two genes for brown eye colour. If 1). occurs, the recessive trait will be expressed. ---> blue eyes If 2). occurs, the dominant trait will be expressed. ---> brown eyes If 3). occurs, the dominant trait will be expressed. ---> brown eyes.
If a pattern of inheritance for a trait is complete dominance then an organism heterozygous for the trait would normally express?
If a trait is dominant, then an organisms heterozygous (hybrid) for that trait would normally show: A) The recessive trait only B) The dominant trait only C) A blend of the recessive and dominant traits D) A phenotype unlike that of either parent B) The dominant trait only! Reason being because heterozygous means the pair of genes are different. When this occurs, only the dominant trait is expressed.
Can full sized dogs have miniature offspring?
yes because if it is heterozygous dog that means that it has a dominant gene ( big ) and a recessive gene ( small ) and that means the dog is Tt capital t is dominant and if they breed with another homozygous recessive dog that means that out of every 4 puppies 2 will be big and 2 will be small ( p.s homozygous means that you have all dominant or recessive genes )
