What are the letters for alleles?

The letters in a Punnett square represent the alleles that may be inherited from each parent. Capital letters represent dominant alleles. Lower-case letters represent recessive alleles.

You record dominant alleles with capital letters and recessives with lower case letters.

recessive alleles are the ones with small letters, for example in Rr, the recessive is the r.

the dominant alleles are represented by uppercase letters and the recessive in lowercase letters.

A punnet square uses letters to represent dominant and recessive alleles.

Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.

Recessive alleles are represented by lowercase letters

capital letters, such as PP equals two dominant alleles, pp equals two recessive alleles.

Most of the time a recessive allele is expressed using lower case letters in comparision to the upper case dominant alleles.

The alleles of the parents. The two letters on each side are the two alleles of one parent. Dr. Claire DNA Diva

If it's not a heterozygous, the alleles would either be two capital letters (TT) or two lowercase letters (tt). This is because the organism has either both two dominant alleles or two recessive alleles.

homozygous dominant means two alleles that are the same that are capital letters, heterozygous recessive means that to alleles are different BUT the same letters in lower case. (alleles for gender) EX: TT, Tt is homozygous dominant tt, tt is heterozgous recessive

Actually, there aren't specific letters. The letters depend on the alleles. For example, if the alleles are A and a, then Aa would be heterozygous, since hetero means different. Homozygous, however, would be two of the same alleles, since homo means same. The homozygous would be AA or AA in this example. hope this helped!

They stand for the parents alleles

(T,T) if t is the letter used for that allele capital letters are used for dominant alleles and lowercase is for recessive.

The letters on the outside of the Punnett square stand for the alleles of each parent. One parent's alleles are written across the top of the square, and the other parent's alleles are written along the left side of the square. The pairs of alleles inside the square represent all the possible genotypes for their offspring.

Lower case letters in a Punnett square represent recessive alleles.

Yes, recessive alleles are represented by lowercase letters.

Recessive alleles are represented in biology as lower case letters.

well it depends on the letters that you are given, recessive alleles are ALWAYS lower case. An example answer would be: ss, where s would represent the recessive allele.

The letters outside (above and usually to the left) of the punnett square represent the alleles (genotypes) of the parents.

Because a genotype is symbology for the actual alleles of a particular gene. Since all genes come in pairs (on the 22 pairs of body chromosomes), one from each chromosome. Examples: BB Bb or bb . Usually capital letters are used to describe dominant alleles and lower case for recessive alleles.

Dominant alleles carry traits or characteristics that will show no matter what. Recessive alleles carry traits where you must be homozygous for the recessive trait in order for it to show. Dominant alleles are represented by capital letters (EX: R or M) Recessive alleles are represented by lower case letters (EX: r or m) In order for a dominant allele to show, you can have either RR or Rr, since it is dominant. However, in…

Dominant alleles are expressed regardless of any other alleles. Recessive alleles are not expressed if a dominant allele is present. Dominant alleles are written with capital letters (eg. B or T), recessive with lower case letters (eg. b or t). Dominant - if B codes for black fur - BB and Bb will both end up with black fur. Recessive - if b codes for white fur, only bb will result in white fur.

Question # 1. The letters on the outside of a Punnett square stand for the parent alleles. The alleles are represented by upper case letters and lower case letters, depending on the dominance or recessiveness of a trait. Punnett squares can be as simple as four boxes or as complex as thirty-six boxes. When filling in a Punnett square one should place the parent the two parents at the top and the left side and…
