Answer:
A.a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair
Explanation:
a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair
using C as the allele for hair curl:
Cc x Cc will produce the following genotypes: CC, Cc, Cc, cc
25% will be homozygous dominant (curly hair)
50% will be heterozygous (curly hair)
25% will be homozygous recessive (straight hair)
combine the curly hair genotypes since the question asked about phenotypes which results in 75% curly and 25% straight.
Answer:
Dead plant matter
Explanation:
Saprotrophs feed by a process known as absorptive nutrition, in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph.
They grow much faster and they grow to be larger than normal crops.
Darwin reasoned that natural selection organisms had adapted to new environments, giving rise to new species. It is a principle of speciation.
<h3>Speciation, natural selection and environment</h3>
Different environmental pressures (e.g. the type of food) lead to different evolutionary pathways in genetically related organisms.
The organisms subject to different environments evolve as a consequence of natural selection in order to adapt (adjust) to their corresponding environments.
In consequence, this process may eventually lead to speciation due to the emergence of reproductive isolation barriers.
