8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the
Eddi Din [679]

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

                R                   B

R                RR               RB

R                RR               RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Focus on the evolution of horn size in the Bighorn sheep population from 1950 to present. What would you predict would happen if
dalvyx [7]

Answer:

The correct answer is option e) "Over time, we could see an increase in the H1 allele frequency".

Explanation:

The bighorn sheep (Ovis canadensis) is a species that is a very attractive for hunters because of its long horns. This negative human influence has make that bighorn sheep with long horns struggle to survive and reproduce. Horn size in bighorn sheep is determined primarly by a gene called HRN, which has two alleles H1 (for long horns) and H2 (for smaller horns). if hunting were discontinued for bighorn sheep in a large population we can predict that over time, we could see an increase in the H1 allele frequency, because in this population bighorn sheep with long horns will have better chances of surviving.

What affects algal growth with increasing depth in the ocean?
andrew-mc [135]
The answer is light.

One of the factors that affect photosynthesis is light. Without light, the photosynthetic rate is reduced or even stopped which consequently affect algal growth. With increasing depth in the ocean, there is less sunlight present. Still, a<span>lgae have accessory photosynthetic plastids other than the chloroplasts</span><span> that can absorb different light in greater ocean depths. This helps them to maximum use sunlight in such conditions. But, in the end, at some particular depth, they would not be able to survive.</span>
