Answer:
25% of the offsprings will be BBCC
Explanation:
This is a typical dihybrid cross involving two distinct genes. One coding for fur colour and the other for claw sharpness. The allele for brown fur (B) is dominant over the allele for black fur (b) in the first gene while the allele for sharp claws (C) is dominant over the allele for dull claws (c) in the second gene.
In a cross between parents with genotypes: BbCc x BBCC , each parent will produce four possible allelic combinations of gametes as follows:
BbCc: BC, Bc, bC, bc
BBCC: BC, BC, BC, BC
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced with four distinct genotypes:
BBCC (4)
BBCc (4)
BbCC (4)
BbCc (4)
According to the question, an offspring that is homozygous dominant for both traits will possess a genotype: BBCC
N.B: Homozygous dominant means contains same alleles for the dominant trait.
Hence, offsprings with genotype, BBCC, from this cross are expected to be 4 out of the 16 possible offsprings. Hence, the percentage is 4/16 × 100 = 25%.
The secondary level of consumers will be affected trace amounts of pesticides, like DDT, that run off into lakes, streams and ponds.
<h3>What are Producers</h3>
Producers are mainly plants that undergo photosynthesis to produce carbohydrates and oxygen.
<h3>Consumers</h3>
Consumers are herbivores or canivores or omnivores that feed on primary producers like plans and others.
- Consumers can be primary which feed on plants examples are goats.
- Secondary consumer are canivores that feed on meat of other animals, they feed on primary consumer.
- Tertiary consumers feed on both plants and meat of other plants.
Therefore, The secondary level of consumers such as fish will be affected trace amounts of pesticides, like DDT, that run off into lakes, streams and ponds because they live in water and their food is in water. Once the substances are in their water, it will become toxic and can lead to their deaths.
