Answer:
Genotype of the parental plant that produced round, yellow seeds is RRgg
Explanation:
Let us say that allele for round shape (R) is dominant over allele for wrinkled shape(r)
and allele for green color (G) is dominant over allele for yellow color of seed.
So a wrinkled green seed will have genotype either "rrGG" or "rrGg"
Like wise a round, yellow seeds will have genotype either "RRgg" or "Rrgg"
It is given that In the F1 generation, half of the plants produced round, yellow seeds and the other half produced round, green seeds.
So if a cross is carried between rrGg and RRgg, the following offspring will be produces
rG rG rg rg
Rg RrGg RrGg Rrgg Rrgg
Rg RrGg RrGg Rrgg Rrgg
Rg RrGg RrGg Rrgg Rrgg
Rg RrGg RrGg Rrgg Rrgg
So genotype “RrGg” gives round and green seeds
And genotype “Rrgg” gives round and green seed
Thus, genotype of the parental plant that produced round, yellow seeds is RRgg
The answer is 0 percent.
If we represent dominant trait (wrinkled seeds) with A and recessive trait (non-wrinkled seeds) with a, then genotypes are AA (dominant homozygous), Aa (heterozygous), and aa (recessive homozygous). The phenotype of wrinkled seed is determined by genotypes either Aa or AA. Since the cross of a plant with wrinkled seed with a plant with non-wrinkled sees gives only wrinkled-seeded offspring, the plant with wrinkled seeds must be dominant heterozygous.
Let's look at both examples.
If wrinked-seeded parent contains one non-wrinkled allele, it must be heterozygous (Aa):
Parents: Aa x aa
Offspring: Aa Aa aa aa
So, the 50% of offspring has wrinkled seeds and 50% has <span>non-wrinkled seeds.
If </span><span>the wrinkled-seeded parent does not contain any non-wrinkled allele:
</span>Parents: AA x aa
Offspring: Aa<span> Aa Aa Aa
</span><span>
Thus, al</span><span>l of the offspring are heterozygous and all of them have wrinkled seeds.</span>
Crossing over can lead to an abnormal genome if the exchange is not done equally, which can lead to an in-utero death or congenital diseases.
Answer:
Genes are made up of DNA.. DNA is the molecule that is the hereditary material in all living cells. The color of your hair,skin,eyes etc,, are all controlled in part by your genetic information
