gametic การใช้

• :Are gametic disequilibrium and linkage disequilibrium synonymous?
• Most often other processes occurring in plants and animals maintain gametic isolation and species distinction.
• The sporic life cycle can be considered a fusion of the gametic and zygotic life cycles.
• The triploid individual reproduces by gynogenesis, a process triggered by the presence of sperm but not involving gametic fusion.
• MHC-mediated mate choice may also occur after copulation at the gametic level, through sperm competition or female cryptic choice.
• If a female is injected with 11-ketotestosterone, it will cause a precocious change in gonadal, gametic and behavioural sex.
• Several asexual species of whiptail lizards have been observed to engage in mating and pair-bonding despite the lack of gametic fusion.
• For individuals heterozygous at both loci, the gametic phase is ambiguous-in these cases, you don't know which haplotype you have, e . g ., TA vs AT.
• As a first step, Robertson said, he would allow cloning for the small number of couples who suffer " gametic infertility, " such as a man who can produce no sperm.
• In the " gametic life cycle " or " diplontic life cycle ", of which humans are a part, the organism is diploid, grown from a diploid cell called the zygote.
• The two possible arrangements, cis and trans, of alleles in a double heterozygote are referred to as gametic phases, and " phasing " is the process of determining which of the two is present in a given individual.
• In "'gametic meiosis "', instead of immediately dividing " meiotically " to produce haploid cells, the zygote divides " mitotically " to produce a multicellular diploid individual or a group of more unicellular diploid cells.
• The cycles differ in when mitosis ( growth ) occurs . "'Zygotic meiosis "'and "'gametic meiosis "'have one mitotic stage : mitosis occurs during the " n " phase in zygotic meiosis and during the 2 " n " phase in gametic meiosis.
• The cycles differ in when mitosis ( growth ) occurs . "'Zygotic meiosis "'and "'gametic meiosis "'have one mitotic stage : mitosis occurs during the " n " phase in zygotic meiosis and during the 2 " n " phase in gametic meiosis.
• Therefore, zygotic and gametic meiosis are collectively termed "'haplobiontic "'( single mitotic phase, not to be confused with haplontic ) . "'Sporic meiosis "', on the other hand, has mitosis in two stages, both the diploid and haploid stages, termed "'diplobiontic "'( not to be confused with diplontic ).
• In summary then, under random fertilization, the zygote ( genotype ) frequencies are the quadratic expansion of the gametic ( allelic ) frequencies : ( p + q ) ^ 2 = p ^ 2 + 2pq + q ^ 2 = 1 . ( The " = 1 " states that the frequencies are in fraction form, not percentages; and that there are no omissions within the framework proposed .)
• For example, if testing sperm from a crime scene, how does one prove it matches to a suspect if the sperm is meiotic / haploid / gametic, while presumably a DNA sample obtained from a suspect is mitotic / diploid / somatic . ( Pardon all the slashes there, but I'm not 100 % on which is the best terminology . ) Thanks in advance, talk ) 00 : 47, 4 March 2014 ( UTC)
