Cuanto pesa y mide el hueso frontal-> How much does the frontal bone weigh and measure?
This depends on whose frontal bone you are weighing and measuring. Please include a picture for reference next time if you want specific answers.
Answer:
It is a trait highly influenced by environmental factors (i.e., it has low heritability)
Explanation:
In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.
Answer:
Spore/sporophyte
Explanation:
The sporophyte is the generation of plants that bear spores. Sporophytes are formed by a division in the zygote and are mostly diploid in nature. The specific structures present on the sporophyte are called sporangia. Spore mother cells present inside the sporangia undergo meiosis to produce haploid spores. For example, the diploid microspore mother cells present in the microsporangia in the anther of flowering plants divide by meiosis to produce haploid microspores.
Answer:
be genotypically different
Explanation:
- Widow's peak is an example of a dominantly inherited trait, this means that any individual who receives even a single copy of the dominant allele would have a widow's peak present in the phenotype.
- In the given question, the cross is made between a homozygous dominant individual (let the genotype be WW) and a heterozygote (Genotype Ww).
- The cross can be represented as follows :
WW X Ww ----> WW Ww Ww WW
From the cross it can be seen that the<em> offsprings will have the genotype of either WW or Ww</em>, however, since W is dominant over w, the phenotype will always be the presence of widow's peak.
