Cats masu launi
A Cats masu launi, wanda kuma aka sani da kulawa, ana nuna su ta hanyar gabatar da ƙirar launi ta musamman a cikin rigar. Furfinta yana da tabarau na orange, baki da fari. Rabon kowane launi yana canzawa.
A cikin kyanwa akwai launuka uku na asali, baki, orange da fari. Sauran launuka sune sakamakon gradients da gauraye na waɗanda suka gabata.
Kwayoyin halittar dabbobin suna da alhakin tsarin gashi, tsintsiya, madaidaiciya, ko mottled, kazalika da launi da daidaita launi na fur.
Menene ke ƙayyade launin gashi?
Launin fur a cikin kuliyoyi shine fasalin jima'i. Wannan yana nufin cewa ana samun bayanai don launin gashi a cikin chromosomes na jima'i.
Chromosomes su ne tsarukan da ake samu a tsakiya na sel kuma sun ƙunshi dukkan kwayoyin halittar dabba. Cats suna da chromosomes 38: 19 daga uwa da 19 daga uba. Jima'i shine waɗancan chromosomes waɗanda ke ƙayyade jima'i kuma kowannensu iyaye ne ke ba su.
Cats, kamar duk dabbobi masu shayarwa, suna da chromosomes na jima'i biyu: X da Y. Uwar tana ba da X chromosome kuma uban na iya ba da X ko Y.
- XX: Mace
- XY: Namiji
A launin baki da lemu suna kan chromosome X. Ma'ana, don su bayyana kansu, dole ne chromosome X ya kasance. Namiji yana da X ɗaya kawai, don haka zai kasance baki ko orange. Mace masu X guda biyu na iya samun kwayoyin halittar baƙar fata da lemu.
A gefe guda, da Farin launi ba a shiga cikin jima'i na dabba ba. Yana gabatar da kansa ba tare da la'akari da jinsi ba. A saboda wannan dalili cat zai iya samun dukkan launuka uku. Domin suna da chromosomes x biyu kuma fararen shima ya bayyana.
haɗuwa
Dangane da kyautar chromosomal da mutum ya karɓa, ɗaya ko wani launi zai bayyana. Baƙi da lemu ana rikodin su akan chromosome iri ɗaya, idan X0 allele yana nan cat zai zama orange idan Xo zai kasance baki. A cikin shari'ar X0Xo, lokacin da ɗayan kwayoyin halitta ba ya aiki, yana da alhakin bayyanar tricolor.
Mace na iya gadon haɗuwa uku:
