What else can I help you with?
How many combinations of alleles could there be in zygotes produced by crossing the following parents TT x Tt?
When crossing the parents TT (homozygous dominant) and Tt (heterozygous), the possible combinations of alleles in the zygotes can be determined. The TT parent can only contribute a T allele, while the Tt parent can contribute either a T or a t allele. Therefore, the possible combinations of alleles in the zygotes are TT and Tt, resulting in two distinct combinations.
How many chromosomes will zygotes have?
if it is a human chromosome it will have 32 chromosomes
How many chromosome do normal mice zygotes contain?
40.
What happens when zygotes have serious chromosomal problems?
Most zygotes with serious chromosomal problems are born with severe mental and physical disabilities; many die before being born or shortly thereafter.
How many time a couple can perform sex in a day?
Depends on the couple. Everyone is different. There is no number on this.
What percent of zygotes become successfully implanted?
Approximately 25-30% of zygotes become successfully implanted in the uterus. Many factors can affect successful implantation, such as the health of the embryo and the receptivity of the uterine lining.
How many chromosomes does an organism reproductive cells and zygotes have?
It has half of whatever the organism's regular cells have.

The answer is 40
Why do ferns produce so many spores and why don't flowering seeds produce as many seeds?
Because fern spores germinate to produce gametophytes on which male and female reproductive organs are produced for sexual reproduction. Likewise in flowering plants large number of pollen grains are produced to ensure gametic union. Once the fertilization is achieved the sporophytic generation begins and there is surity of survival in diploid phase. Hence gametes are produced in plenty and zygotes and seeds in limited ammount.
