Answer:
Translocation
Explanation:
Changes in chromosome include deletions, duplications, inversions, and translocations.
- Deletion occurs when an end of a chromosome breaks off.
- Duplication is the presence of a chromosome segment more than once in the same chromosome.
- Translocation is when a fragment of chromosomal breakage join a nonhomologous chromosome.
- Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes.
- Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" together.
Answer:
Epistasis
Explanation:
In epistasis, the interaction between genes is inimical, such that one gene masks or interferes with the expression of another. “Epistasis” is a word coined of Greek roots that mean “standing upon.” The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking. The cause of the biochemical basis of epistasis is a genetic pathway in which the expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway.
The example of epistasis given is the pigmentation of mice. we were told that "if a mouse has two recessive alleles for coat color, it is always albino no matter what the genotype of other genes involved in coat color"
Let say recessive allele (rr), it is always albino irrespective of other type of other genes, this is true in the stance that epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same genotype.
Methane is the gas that is strongly correlated with Earth's heating and cooling patterns. Did you know that cow's flatulence is methane gas?! Interesting fact!
The probability of producing a transgender = None ( D ) when the father is gay
The probability of producing male gamete is not affected by the sexual orientation of the Father because the production of the male gamete is carried by the spermatogonia found in the testes of a male. and every male specie regardless of your sexual orientation have testicles where the spermatogonia undergoes mitotic divisions to produce the male gametes.
Hence the probability of producing a transgender given that the father is gay is non-existent i.e.0%
