During meiosis one cell? divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our sex cells or gametes? (eggs in females and sperm in males).
B- black allele;
b- brown allele;
The parental cross is true-breeding because both the male and the female are homo zygotes, so: BBx bb
The F1 generation will be all black heterozygote: Bb
The F2 generation will be between mice of the F1 generation and they all have the same genotype:Bb xBb
In this cross it would result in:
1/4 of the plants being black homozygote-BB 25%
2/4 of the plants being black heterozygote- Bb- 50%
1/4 of the plants being brown homozygote- bb- 25%
answer: 25%+25%=50% are homozygotes
Answer:
It is the 2nd one
Explanation:
For example when you grow your cells multiply or divide into more cells. So that's just in general, but it works for this two.
Answer:
Human polygenic inheritance are height, skin color, eye color and weight.
Explanation:
Polygenic inheritance is the set responsible for many characters that appear simple from the surface. Many characters such as weight, shape, height, color, and metabolism are governed by the cumulative effect of many genes.
Polygenic inheritance is not expressed at all as discrete characters, as in the case of Mendelian characters. Instead, polygenic characters are recognized by being expressed as graduations of small differences (a continuous variation). The result forms a curve with an average value at the peak and extreme values in both directions.
