What are two source of genetic diversity in meiosis? Choose the correct answer: Whether it is eggs or sperm being produced through meiosis, under normal circumstances, each gamete ends up with A) equal amounts of cytoplasm. B) exactly two copies of each chromosome. C) the same alleles. D...
Alleles are two or more alternative forms of a gene that arise by mutation and are located at the same place on a chromosome. It is of various types like lethal alleles, multiple alleles, etc. Answer and Explanation: When there are more than two al...
The ancestral Y-linked genes are close to partial ARR17-like duplicates23–25, and two ancestral X-Y homologous gene pairs diverged in the progenitor of the Vetrix-clade25. To understand how different parental sex chromosome systems affect allopolyploidization, we assemble a haplotype-resolved ...
In autopolyploid lineages, where both genome copies arise from the same species7, polyploid progeny could inherit the sex chromosomes from the diploid ancestor8. However, allopolyploidy, where hybridization between species combines one duplicated copy of each ancestral genome, could lead to diverse sex...
Alleles a different form of a gene that may be dominant or recessive Homozygous An organism with two of the same copies of an allele Heterozygous An organism with two different copies of an allele Genotype Combination of Alleles Phenotype how alleles appear on the outside Hugo De Vries coined ...
Deletion of either system (∆kaiAB1C1 or ∆kaiA3B3C3) alters the period of the cellular backscattering rhythm. Furthermore, both oscillators are required to maintain high-amplitude, self-sustained backscatter oscillations with a period of approximately 24 h, indicating their interconnected ...
If two parents with free earlobes have a child with attached earlobes, both parents must have the genotype of heterozygous (Ee) for earlobe shape. Free earlobes (E) is dominant over attached earlobes (e), so the presence of attac...
This is due to the sex-bias in the transmission pattern of these chromosomes, where one sex carries two copies and the other sex only one copy. The uneven dose of X and Z chromosomes between the sexes should lead to an accumulation of sexually antagonistic genes on these chromosomes, i.e...
Individuals with different alleles for a single trait are called ___ Alleles are: a. recessive traits b. dominant traits c. exact copies of the same trait d. alternate versions of the same trait If someone is said to be heterozygous for a trait, it means that: a...
Can two populations have the same allele frequencies, but different genotype frequencies? Hardy-Weinberg Principle: Hardy-Weinberg principle describes the stability of the frequency of genotypes and alleles in the absence of extraneous variables like mutations, genetic drift, or gene...
