Answer:
1. DNA sequence
Since DNA is passed from parents to offspring, it is the most accurate way of
determining evolutionary relationships between species.
2. eukaryotic
3. protists and plants
4. species F/6
If we talk about guinea pigs, the trait of hair length is controlled by a gene with two alleles.
Allele for short hair (S) is dominant on the allele for the long hair (s).
The texture of hair texture is controlled by a gene with two alleles. It can be rough or smooth, and the allele for rough hair (R) is dominant on allele for smooth hair (r).
Now coming towards the question:
- A female guinea pig is heterozygous for hair texture and homozygous recessive for hair length.
Phenotype of the female will be Rough and long hair.
- A male guinea pig is homozygous dominant for hair texture and hair length.
Phenotype of the male will be Rough and short hair.
Hope it help!
Ansa million. once you're staring at in ordinary terms one technology, it relatively is, all those fruit flies have been produced via 2 mum and dad, then the only plausible parental genotype that provide you a 50/50 ratio is that if the mummy is XwXw and the father is Xry... this gene is carried on the X chromosome, and w represents white eyes and r represents purple eyes. you are able to bypass forward and draw this out in case you like, even yet it provides 50% heterozygous women individuals (with purple eyes, provided that purple is dominant), and 50% white eyed men, who can in ordinary terms inherit Xw from their mom. The Y that they could inherit from the father could have not any effect on their eye shade. it relatively is comparable for women individuals, they are in a position to in ordinary terms inherit Xw from their mom and an Xr from their father, meaning they'll continually be heterozygous for the attention shade gene. 2. returned, set us the genotypes so which you will visualize it; we are going to say that this disease is carried on the X chrmsm (thats whats usually assumed), and the gene for customary creative and prescient is XB, yet for colorblindness its Xb. those are dominant/recessive to boot. So, if the girl is a provider, her genotype is XBXb, and if the male is colorblind, his genotype is XbY. in case you draw this out in a punett sq., you will get 25% heterozygous woman, 25% colorblind woman, 25% well-known male, and 25% colorblind male. so, there's a 50% risk that any baby they have would be colorblind, 50% risk if its a woman, or 50% risk if it relatively is male.wer:
Explanation:
Answer:
<u><em>Genetic variation</em></u> occurs because beneficial traits exist in a collection of genes, and <u><em>gene flow</em></u> makes these traits more prevalent in populations.
Explanation:
In biology, genetic variation can be described as the different genotypes which occur in species of the same kind. This genetic variation allows those organisms to survive on Earth which are better adapted to survive to the environmental changes.
The organisms which are better adapted to live in an environment will reproduce and pass their traits to the offsprings. Over time, these traits will become more prevalent in a population.
