I’m confused on the question what are you trying to find out there equation or anything
In the sentence "The F2 generation phenotypes resulting from the
monohybrid cross of purebreds display a ratio of _____" the word that
correctly completes the sentence is 3:1. In the monohybrid cross of
purebreds, F1 generation will consist of heterozygotes with dominant
phenotype. When F1 generation cross, the F2 generation phenotypes will
be as following: 3 dominant phenotypes (1 dominant homozygote and 2
heterozygotes) and 1 recessive phenotype (1 recessive homozygote).
Answer:
False
Explanation:
Since it's a recessive disorder that means the presence of the dominant allele will overshadow the recessive if it's present. Two recessive alleles have to be present in order for the person to have the disorder.
Which of the following species reproduces by internal fertilization?
a) cats
(b) Toads
(c) The fish
(d) alternative b and c
Answer:
(a) Los gatos
Explanation:
Only cats are capable of internal fertilization from the given choices above.
Internal fertilization is the fusion of gametes within an organism. This process occurs during sexual reproduction within the female.
- Toads and fishes exhibit external fertilization.
- External fertilization occurs where the male sperm externally fertilizes the eggs of the female.
- This usually takes place in a moist or wet place especially water bodies. The liquid medium will transport the sperm to the egg.
In cats, the female specie takes in reproductive cells from the male during coitus and it fertilizes the her eggs to produce a zygote.
Rice Plants need to stand in a lot of water for growth. The Borders (bunds) of a rice field have to be Strong to hold the Water. The Farmer Planted Grass Plants on the Borders because, Grass has Fibrous roots which bind the soil of the bund and hold it together.
<u>Explanation</u> : The Answer itself Explains us well about why the farmer planted those grass plants (i.e.) to increase the strength of the soil. We know that Unity and Teamwork are Strong Words. The Soil and Fibrous Roots show us How Strong those Words are!
