Male has sex chromosomes: One X + one Y
Female has sex chromosomes: Two X
So, Female must contribute by one X chromosome, but male can contribute either by X or Y, if he sends, X chromosome, then Female (Girl) will form, but if he sends Y chromosome, then Male (Boy) will form
Hope this helps!
I think it is carbohydrates
Answer:
D
Explanation:
The acids in your stomach break down the food you eat
I believe it’s true, since Competition will occur between organisms in an ecosystem when both try to use the same resource and the resource is in limited supply. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.
The answers would be:
Genotype Phenotype
Tt Tall stemmed
tt Short stemmed
Genotypic ratio : 2:2 or 1:1
Phenotypic ratio: 2:2 or 1:1

<u>You can read on to see how this was done:</u>
Tall stems (T) are dominant to short stems (t).
First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.
For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.
Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.
Now we can make our Punnett Square.
tt x Tt
<u> t t </u>
<u>T | Tt | Tt</u>
<u>t | tt | tt</u>
Let's list down the genotypes and phenotypic results.
Genotype no. Phenotype
Tt 2 Tall stemmed
tt 2 Short stemmed
So from that we can answer the other questions:
Genotypic ratio : 2:2 or 1:1
Phenotypic ratio: 2:2 or 1:1
