Cricket Karyotype Evolution and Genetics Review

Vocabulary flashcards covering karyotype analysis, chromosome pairing, somatic vs. gamete counts, and parentage testing based on cricket genetics notes.

Cricket A Sex Determination

Identified as female based on having $\text{XX}$ chromosomes.

Cricket B Chromosome Count

Has a total of $18$ chromosomes in its karyotype, where $9$ originated from mom and $9$ from dad.

Chromosome Pairs in Karyotypes

Chromosomes are arranged in pairs because one was inherited from the mother and one from the father.

Cricket D Karyotype Composition

Contains $10$ autosomes and $2$ sex chromosomes in its karyotype.

Somatic Cell Karyotype Identification

Identified as body (somatic) cells rather than sex cells (gametes) because there are $2$ chromosomes together in pairs.

Cricket D Egg Cell Chromosome Content

An egg cell of Cricket D contains $6$ total chromosomes and $1$ sex chromosome.

Parentage Determination

Cannot be determined by looking at karyotypes; it can only be determined by analyzing nitrogen sequences or alleles (DNA).
