Autosomal recessive alleles ( both males and females) and X-linked alleles in females always express themselves in homozygous condition. On other hand, X -chromosome linked recessive allele express singly in males.

∙ 14y agoAn individual that is homozygous recessive for a particular trait carries two copies of the allele that codes for the recessive trait. This allele, often called the "recessive allele" is usually represented by the lowercase form of the letter used for the corresponding dominant trait . The genotype of an organism that is homozygous recessive for a particular trait is represented by a doubling of the appropriate letter, such as "pp".

∙ 13y agoWhen writing dominant and recessive paired traits, the letter representing the trait is capitalized when the allele is the dominant form and lower case when the allele is the recessive form. For instance, to show a hybrid for some trait "A", the genotype would be Aa - one dominant allele (A) and one recessive allele (a). However, this only holds with a completely dominant/completely recessive single gene pair. For straight vs curly hair in humans, both the straight allele (S) and the curly allele (C) are incompletely dominant over each other. A person with straight hair has the genotype SS, a person with curly hair has the genotype CC and a person with wavy hair (intermediate between straight and curly) has the genotype SC. Polymorphic genes (such as for eye color in humans) and multigenetic traits get more complicated in the denomination.

∙ 13y agoIf G is for the gene (allele ) then G is dominant and g, small case letter, is representative of recessives.

Is webbed feet dominant or recessive?
recessive.
The weaker of two genes is called what?
dominant
What are alleles and what are the two forms?
They are traits that are passed on from parent to offspring. There are also two types of alleles; Dominant and recessive.
Are dominant traits more likely to be inheritd then recessive traits?
Yes. When looking at Gregor Mendel's laws of inheritance, the Dominant allele will always be inherited by the offspring, as it is more potent than the 'weaker' recessive allele (unless the recessive allele is present in both parents; this can be in the form of Aa or aa, but it must be present in both for the recessive allele to be present in the offspring). There are other cases, though, such as co-dominance, in which recessive alleles are more likely to be present in the offspring, but speaking in general terms, it is the Dominant (ex. AA / Aa) alleles that show up more commonly in offspring than the recessive (ex. aa) alleles.
Explain how the inheritance of traits is controlled in organisms?
The inheritance of traits is controlled in organisms by genes. These genes come from either one or two parents. The alleles determine what traits are dominant or recessive in the new organism.
Dominant traits are represented by a lower case letter and recessive traits are represented by an upper case letter?
No. Dominant traits are uppercase and recessive traits are lowercase.
What are dominant traits represented?
Recessive
What is the difference dominant and recessive trait?
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
How is a dominant trait represented in a punnett square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
True or false dominant traits are represented by a lower case letter and recessive traits are represented by an upper case letter?
False
How are traits dominant?
Dominant traits are represented as capital letters (D, R, H, J, etc) and recessive traits are represented as lower case letters (d, r, h, j, etc)
What do organisms pass to their offspring?
They pass on traits. There are recessive traits and dominant traits. The dominant trait is normally the one that overpowers recessive
Do dominate traits have capital letters?
No, dominate traits do not have capital letters. The term "dominant traits" refers to the phenotype that is expressed when an individual has one dominant allele for a particular trait. It is not capitalized unless at the start of a sentence.
How dominant and recessive alleles are represented in a Punnett Square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
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.
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
