Dihybrid crosses can be used to predict two independent alleles in the future generation. In echidnas, the allele for brown fur
Mrac [35]

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%.

What are some characteristics of polyploidy organisms<br>​
ruslelena [56]
Polyploidy is the state of a cell or organism having more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent.

A) a moth has two alleles for spots. it can have brown or white spots. the brown spot allele frequency is 0.26. what is the whit
Rufina [12.5K]

<span>The answer is 0.74.</span>

This is derived using the Hardy Weinburg principle of allelic frequency at equilibrium.

p + q = 1

Therefore if q = 0.26; then 1- 0.26  = 0.74

<span>In most occasions, the allele with the higher frequency is usually the dominant one (but not always). </span>

Which of these would be considered a structural adaptation? Answer options with 5 options A. a butterfly migrating south for the
Kruka [31]

Answer: The correct option is

E. a woodpecker using his sharp beak

Explanation:

This is because a structural adaptations refer to characteristics or traits that animals possess and they use in order to adapt or survive in their environment. These refer to the physical characteristics of the animals.

From the question, a wood pecker using a sharp beak is an example of structural because the beak is the characteristics the wood pecker is using to survive in it's environment.
