Compared to the amount of genetic information
miskamm [114]

Answer:

c. One half as much.

Explanation:

The amount of genetic information contained in a normal human sperm cell (23 chromosomes) is one-half as much the information contained in a normal human body cell (46 chromosomes). Sperm cells are produced during meiosis, a specialized division process that <u>reduces the number of chromosomes in half</u>, generating haploid daughter cells.

Which is a benefit of this type of social group structure
MatroZZZ [7]

a social group can be defined as two or more people who interact with one another, share similar characteristics, and collectively have a sense of unity. Other theorists disagree however, and are wary of definitions which stress the importance of interdependence or objective similarity. Instead, researchers within the social identity tradition generally define it as "a group is defined in terms of those who identify themselves as members of the group."[3] Regardless, social groups come in a myriad of sizes and varieties. For example, a society can be viewed as a large social group.

Suppose the two possible alleles for the height gene are tall and short. If short is recessive to tall, provide the symbol repre
navik [9.2K]

Phenotype - short , Tall

Genotype - tt (short) , TT or Tt (tall)

<u>Explanation:</u>

In Mendelian Genetics, <em>Dominant traits</em> are represented by capital letters and <em>Recessive traits</em> are represented by small letters.

So if height is the character considered, then the traits would be short and tall.

Tall is the dominant phenotype and short is the recessive phenotype.

The alleles of the gene for height are T and t.

The genotype for Tall trait is TT or Tt.

The genotype for short trait is tt.

Therefore, the symbol representation of phenotype (Tall) is TT or Tt and for phenotype (short) is tt.
